Applied Micro X-Gene (64-bit ARM) vs Intel Xeon (64-bit x86) Performance and Power Usage

October 26th, 2014 5 comments

A group of researcher at CERN have evaluated Applied Micro X-Gene 1 64-bit ARM XC-1 development board against Intel Xeon E5-2650 and Xeon Phi SE10/7120 systems, and one of them, David Abdurachmanov, presented their findings at ACAT’ 14 conference (Advanced Computing and Analysis Techniques) by listing some of the issues they had to port their software to 64-bit ARM, and performance efficiency of the three systems for data processing of High Energy Physics (HEP) experiments like those at the Large Hadron Collider (LHC), where performance-per-watt is important, as computing systems may scale to several hundred thousands cores.

HEP_Test_Systems_X-Gene_Intel_Xeon
Intel Xeon Phi platform based on Many Integrated Cores (MIC) computer architecture was launched the HPC market, and contrary to the table above features 61 physical cores. Applied X-Gene 1 (40nm process) was used instead of X-Gene 2 built on 28-nm process which was not available at the time. The ARM platform ran Fedora 19, whereas the Intel processor used Scientific Linux CERN 6.5.

The researchers run the CERN’s CMSSW applications for testing. Let’s jump to the results.

AOM_X-Gene_1_vs_Intel_XeonAs expected Intel Xeon processor and Phi coprocessor both have more performance than X-Gene 1 ARM SoC.

X-Gene_Intel_Xeon_Phi_Performance_Per_WattHowever, when it comes to performance-per-watt, APM X-Gene 1 is clearly ahead of Intel Xeon E5-2650 and there’s no comparison against Xeon Phi systems.

The conclusion of the report reads as follows:

We have built the software used by the CMS experiment at CERN, as well as portions of the OSG software stack, for ARMv8 64-bit. It has been made available in the official CMS software package repository and via the CVMFS distributed file system used by Grid sites.

Our initial validation has demonstrated that APM X-Gene 1 Server-on-Chip ARMv8 64-bit solution is a relevant and potentially interesting platform for heterogeneous high-density computing. In the absence of platform specific optimizations in the ARMv8 64-bit GCC compiler used, APM X-Gene 1 shows excellent promise that the APM X-Gene hardware will be a valid competitor to Intel Xeon in term of power efficiency as the software evolves. However, Intel Xeon Phi is a completely different category of product. As APM X-Gene 2 is being sampled right now, built on the TMSC 28nm process, we look forward to extending our work to include it into our comparison.

You can read the full report “Heterogeneous High Throughput Scientific Computing with APM X-Gene and Intel Xeon Phi” for details.

October 25th, 2014 5 comments

LG has been making mobile devices since 1997, has entered the smartphone market in 2010, and they’ve now decided to foray into mobile SoC, with their very first SoC being an octa-core Cortex A15/A7 processor called NUCLUN, and found in their latest G3 Screen smartphone running Android 4.4.4.

LG_G3_Screen_NUCLUN_Processor

Details about NUCLUN processor are sparse, but the company did provide some specifications for LG G3 Screen smartphone:

  • SoC – LG NUCLUN (LG7111) Octa-Core big.LITTLE processor with four ARM Cortex A15 cores @ 1.5GHz, four ARM Cortex A7 cores @ 1.2GHz.
  • System Memory – 2GB RAM
  • Storage – 32GB  eMMC + MicroSD slot
  • Display – 5.9″ Full HD IPS touchscreen
  • Camera – 13MP OIS+ rear camera, 2.1MP front-facing camera
  • Network – LTE-A Cat.6 for up to 225Mbps download speed.
  • Battery – 3,000mAh
  • Dimensions – 157.8x 81.8x 9.5mm
  • Weight – 182g

The phone,  also codenamed as LG Liger F490L, F490K or F490S (depending on carrier) , runs Android 4.4.4 KitKat on top of Linux 3.10.40+. The GPU was not listed, but based on some CPU-Z screenshots a PowerVR GPU (Series 6?) is used in NUCLUN. The firmware may not be optimized for performance just yet, as Antutu 5.1.5 score is just 25,460 points.

MXQ S85 Android TV Box (Amlogic S805) Review

October 11th, 2014 20 comments

MXQ S85 and EM6Q-MXQ are two main Full HD H.265 Android media players based on Amlogic S805 currently selling on Chinese online stores. I’m lucky enough to have received both, and I’ve already completed the review for EM6Q-MXQ, so today I’ll complete MXQ S85 review and compare both devices. I’ve already taken picture of the device, accessories, and checked out the board’s components in my unboxing post, so in this post, I’ll focus on the user interface, evaluate performance, and test most hardware features of this media player.

First Boot, Settings and First Impressions

I’ve started by a quick test of the IR remote control, and it works as expected after inserting two AAA batteries, before switching to Mele F10 Deluxe air mouse for convenience. I’ve connected all ports of the device except the S/PDIF output: Ethernet cable, HDMI and AV cables, micro SD card, USB hard drive, USB webcam, and a USB hub with two RF dongles for my air mouse and gamepad.  I’ve connected the power, pressed the power button opn the top of the box, a Blue LED turns off, “Google TV” icon appears on TV and in a little more than 40 seconds the boot completes. It’s not quite as fast as higher RK3288 TV boxes (20s), but it’s much better than the boot time on EM6Q-MXQ (1m 50s), so the flash must be faster.

Home Screen (Click for Original Size)

Home Screen (Click for Original Size)

The user interface is the Android Home screen, but you can also switch the MediaBox launcher with a Metro-style user interface found in many Amlogic S80X TV boxes, by going to the “Home” section in Android settings. The box automatically selected 1080p60 Hz video output, and the user interface resolution is 1920×1080 as you can infer from the screenshot above. I’ve noticed that switching to 720p still keep the user interface to 1920×1080 resolution, so there’s no performance gain doing so.

The “Setting” menu is based on the same Metro-style interface as EM6Q-MXQ with four sub menus: Network, Display, Advanced and Other. I’ve highlighted difference in bold.

  • Network – Enable and configure Wi-Fi or Ethernet
  • Display:
    • Automatic or manual HDMI resolution: 480p/i @ 60 Hz, 576p/i @ 50 Hz, 720p @ 50/60 Hz, 1080i @ 50/60 Hz, or 1080p @ 24/50/60 Hz
    • CVBS Mode Setting: 480 CVBS or 576 CVBS (if Composite output selected on TV).
    • Hide or Show status bar
    • Display Position
    • Screen Save (Never, 4, 8 or 12 minutes)
  • Advanced:
    • Miracast
    • Remote Control (app)
    • CEC Control
    • Location for weather (Chinese cities only)
    • Screen Orientation settings
    • Digital Audio Output (Auto, PCM, S/PDIF pass-through, or HDMI pass-through)
  • Other – System Update: Local file or OTA (not working), Backup, and “More Settings” for standard Android Settings.

So it’s exactly the same as EM6Q-MXQ, except the current firmware also supports 1080p @ 24 Hz.

I’ve also tested composite output, and both 480 CVBS and 576 CVBS settings worked fine. There’s no component (YPbPr) output in this box.

I have not made a video for MXQ S85, because it’s very similar to EM6Q-MXQ, except you have the option to switch between the Android home screen or MediaBox launcher, 1080p24 is supported, and S85 is a little more responsive. But you can watch the video I shot for EM6Q-MXQ if you haven’t already where I walk through the user interface and settings, XBMC user interface (1920×1080 UI rendered at 30 fps), and show H.265 video playback in MX Player.

About_MXQ_S85MXQ-S85 comes with an 8GB NAND flash with a single partition (8.00 GB – black magic again…), and at the end of the review I still had 4.01 GB free. Looking into “About MediaBox” section, we can find out that the model number is “S85″, and the system runs Android 4.4.2 on top of Linux kernel 3.10.33. The firmware is rooted, and after I started the review I found firmware 106k4 (an updated to version 105k4 used for the review), which you can probably flash with Amlogic USB flash tool, but I have not tried.

All apps I needed for the review could be installed with Google Play Store including Antutu, 3D Mark, ES File Explorer, MX Player, Beach Buggy Blitz, A1SD benchmark, Sixaxis Controller, etc… However, as I scrolled through the list of apps installed on other Android devices, there were a few incompatible apps notably some messaging apps (Facebook Messenger, Whatsapp), Instagram, Google Translate, and a few others. But you can usually work around these issues by spoofing your device name with an app (paid), or changing build.prop. I’ve also downloaded and installed Amazon AppStore, in order to play Riptide GP2.

Albeit the box features a power button, power handling is not perfect, as a clean power off is not possible. You can either use the remote control power button to enter and exit standby, and the power button on the unit, can be used to achieve real power off, and to turn the device on, but it’s and hardware power off which powers off the device immediately, Android does not cleanly shuts down. The device temperature is pretty cool: 40°C and 46°C measured with an infrared thermometer respectively on the top and bottom of the box, right after running Android 5 benchmark. And after playing Riptide GP2 for about 10 minutes (at which stage the game froze), the maximum temperature on top and bottom reached 42°C and 46°C…

The system very pretty stable, but just like with EM6Q-MXQ, attempting to play a 4K video in XBMC will freeze the system requiring a hard reboot. However, the flash is fast enough no to experience various slowdowns, or making apps randomly exit. Android did pop up the “app not responding” windows at load time for some games, so it’s not perfect, but answering “wait” will start the games normally. Nevertheless, although it’s clearly not as snappy as the latest Amlogic S802 or Rockchip RK3288 based mini PCs, I did not find MXQ S85 frustrating to use, unlike EM6Q-MXQ.

Video Playback

Videos were playing from SAMBA share in Ubuntu 14.04 over Ethernet using XBMC 13.1 pre-installed in the system, switching to MX Player for videos that failed to play. I had no problems connect to SAMBA with XBMC and ES File Explorer.

I started with videos from samplemedia.linaro.org, H.265/HEVC videos by Elecard, as well as a (low resolution) VP9 video:

  • H.264 codec / MP4 container (Big Buck Bunny), 480p/720p/1080p – OK
  • MPEG2 codec / MPG container, 480p/720p/1080p – OK
  • MPEG4 codec, AVI container 480p/720p/1080p – OK
  • VC1 codec (WMV), 480p/720p/1080p – OK
  • Real Media (RMVB) – RV8, RV9, and RV10 – OK but not that smooth (S/W decode)
  • WebM / VP8 – 480p OK, 720p some rare parts in slowmo, 1080p plays in slow motion all the time.
  • H.265 codec / MPEG TS container
    • XBMC – Audio only
    • MX Player – OK (H/W decode), but seeking does not work properly. It will switch to S/W decode, and the video becomes unwatchable.
  • WebM / VP9 (no audio in video)
    • XBMC – Won’t even start
    • MX Player – OK (H/W decode).

Then I played some higher bitrate videos:

  • ED_HD.avi – XBMC: audio only; MX Player: black screen only, no audio.
  • big_buck_bunny_1080p_surround.avi (1080p H.264 – 12 Mbps) – OK.
  • h264_1080p_hp_4.1_40mbps_birds.mkv (40 Mbps) – OK
  • hddvd_demo_17.5Mbps_1080p_VC1.mkv (17.5Mbps) – OK, but could be smoother, and XBMC reports skipped frames regularly.
  • Jellyfish-120-Mbps.mkv (120 Mbps video without audio) – OK (Played from USB hard drive)

Videos with high definition audio codec could be played in XBMC (with performance issues), but not in MX Player (except AC3):

  • AC3 – OK
  • Dolby Digital 5.1 / 7.1 – OK
  • TrueHD 5.1 & 7.1 – OK
  • DTS-MA – OK
  • DTS-HR – SAMBA: Audio completely cuts after a few seconds. USB: No problem with audio, but video feels slow.

A Blu-ray ISO video (Sintel-Bluray.iso) played perfectly in XBMC.

I tested over a dozen other videos from my library (AVI, MKV, FLV, VOB/IFO, and MP4 containers), and they could all play with any A/V sync issues. I also watched a complete 1080p video (1h50 / MKV / 3GB), so no problem with stability either.

Links to various video samples used in this review and be found in “Where to get video, audio and images samples” post and comments.

Network Performance (Wi-Fi and Ethernet)

A 278 MB file between a SAMBA share (Ubuntu 14.04) and the internal flash, and vice versa, repeating the test three times with ES File Explorer. Wi-Fi transfer speed is still pretty good @ 2.95 MB/s on average, although not quite as fast as EM6Q-MXQ media player.

Wi-Fi Transfer Rate in MB/s

Ethernet worked at 100 Mbps connected to my Gigabit Ethernet switch, with performance similar its competitor. Tronsmart Orion R28 Meta is way ahead, simply because it’s the only box I have that actually supports Gigabit Ethernet.

Ethernet Transfer Rate in MB/s

Ethernet Transfer Rate in MB/s

For a raw benchmark of Ethernet performance, I ran iPerf app using “iperf -t 60 -c 192.168.0.104 -d” command line. It does not quite maxes out Fast Ethernet bandwidth like Rockchip RK3288, but results are similar to EM6Q-MXQ just like with the test above.

Miscellaneous Tests

Bluetooth

Contrary to the version of EM6Q-MXQ I reviewed, MXQ S85 comes with Bluetooth.

I could transfer pictures from my Android phone to the box over Bluetooth, Sixaxis Compatibility Checker appeared to support PS3 wireless gamepads, but my controller was not recognized.

Bluetooth LE (Smart) was tested with Vidonn X5 activity tracker, but unfortunately the app could not locate the device over BLE.

Storage

FAT32 formatted micro SD card and USB flash drive could be recognized and properly mounted by the system
Only NTFS and FAT32 partition on my USB 3.0 hard drive could be mounted and accessed. That’s common to all Android mini PCs I tested, except A80 OptimusBoard which could mount the EXT-4 partition too (but in read-only mode).

File System Read Write
NTFS OK OK
EXT-4 Not mounted Not mounted
FAT32 OK OK
BTRFS Not mounted Not mounted

A1 SD Bench was used to benchmark USB hard drive and internal flash performance. The read speed was 16.92 MB/s, and the write speed of 21.87MB/s fore NTFS partition in /storage/external_storage/sda1, both results being weak.

MXQ_S85_USB_NTFS_Benchmark

USB HDD (NTFS) Read and Write Speeds

The NAND flash speed is clearly not outstanding at 15.8 MB/s (read) and 6.83 MB/s (write), but still better than EM6Q-MXQ, and apparently good enough for a smooth operation of the device most of the time.

MXQ_S85_NAND_Flash_BenchmarkUSB Webcam

I had troubles with both Skype and Google Hangouts with my USB webcam. I did manage to see the image in Skype once, but never long enough to make a phone call. The camera is not detected at all in Hangouts.

Gaming

Candy Crush Saga, Beach Buggy Blitz, and Riptide GP2 could run on the box. I played Candy Crush Saga with my air mouse, and switched to Tronsmart Mars G01 wireless gamepad for Beach Buggy Blitz and Riptide GP2. For each game, the system showed up pop up with “App XXX is not responding. Do you want to close it?”, but selecting “Wait” could load the games just fine. Beach Buggy Blitz framerate felt good using the default settings (low res), but I did notice some very short freezes (<1s) from time to time. Riptide GP2 is not really enjoyable with default settings (high resolution), but lowering the resolution makes it relatively enjoyable to play. Riptide GP2 freezing I encountered on other Amlogic s802/S805 devices, and Allwinner A80 development board occurred yet again, after just around 10 minutes of play time. I’m not sure if the game itself is buggy, or the GPU drivers/libraries are. I checked the maximum temperature on the top and bottom of the device at that time, and I got 42°C and 46°C.

Even if games can run, the gaming experience is not great, and you should really consider spending more to get a Rockchip RK3288, or not as good, Amlogic S802 devices if you are really interested in playing games. Nvidia Tegra K1 devices should even be better but in a completely different price category.

MXQ S85 Benchmarks

CPU-Z shows the device is indeed powered a quad ARM Cortex A5 processor clocked between 24 MHz and 1.49 GHz, but instead of using a performance governor, MXQ S85 is using a hotplug (on-demand). The board is m201, which can be a useful thing to know in case you download firmware files. FYR, EM6Q-MXQ is based on hd18t board.

Amlogic_S805_CPU-Z_MXQ_S85

The devices gets 16,448 points in Antutu 5.1 which is consistent with the score I got with EM6Q-MXQ (16,647).

MXQ_S85_Antutu_5.1

There are some differences in Vellamo 3 however, with a lower Browser score (812 vs 1061), a higher multicore score (1319 vs 1139). The metal score is about the same.

Vellamo_3_MXQ_S85

Ice Storm Extreme test in 3DMark is about the same with 2,308 points (vs 2,325 for EM6Q-MXQ), and clearly shows the relatively low performance of the quad core Mali-450MP GPU used in S805 compared to high-end SoC with better GPUs.

S85_3D_Mark_Ice_Storm_Extreme

Conclusion

MXQ S85 is actually a pretty good device and performance considering the price (<$50). Wi-Fi and Ethernet are pretty decent, video codecs/containers is quite good in XBMC, and H.265 can be played in MX Player, but not yet in XBMC. The firmware is pretty stable, and I did not come across massive slowdowns like in EM6Q-MXQ.

PRO:

  • The firmware is stable, relatively smooth to operate, and only hung when trying to play 4K videos
  • Good XBMC support.
  • HEVC/H.265 hardware video decoding support. Working in MX Player, but not with XBMC (yet)
  • Very good price/performance ratio.
  • Good Wi-Fi, and decent Ethernet performance
  • Video Output – Supports 1080p24/50/60 (but no 25/30 Hz), and composite output (NTSC/PAL).

CONS:

  • Despite having a power button, power off is not perfect (no clean power off)
  • Bluetooth Low Energy (mostly used for wearables) is not currently supported.
  • OTA firmware upgrade is not working
  • USB / NTFS storage performance is disappointing.
  • USB webcam did not work reliably for me in either Skype and Hangouts.
  • “App xxx not responding” message may appear while loading large apps such as games.

Gearbest provided the sample for review, so if you are interested in purchasing you could do so on their site for $47.99 (with MXQBCM coupon), or for $45.99 (with MXQCM coupon) for the version without Bluetooth. Coupons are valid until November 30, 2014. MXQ-S85 can also be found on other stores including DealExtreme, Amazon US, Dealsmachines, and Aliexpress.

Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board

October 4th, 2014 6 comments

Sine A80 OptimusBoard is the first ARM hardware that supports both USB 3.0 and Gigabit that I’ve ever owned, so I though it might be interesting to see what performance I could get with a USB 3.0 hard drive through the USB 3.0 OTG port of the board. For testing purpose, I bought a USB 3.0 OTG adapter on Ebay, but I did not look closely enough as it turned out to be only a USB 3.0 OTG to USB 2.0 female adapter capable of USB 2.0 speeds… Kind of useless item since you can plug a standard USB 2.0 OTG adapter into a USB 3.0 OTG receptacle. But I tried my hard drive anyway, and quickly realized write performance was very poor at 3 MB/s on the NTFS partition, whereas most other devices can handle at least15 MB/s, and usually over 25 MB/s. So I contacted Allwinner with this issue, and they were kind enough to look into it, and provided an updated firmware.

Today, I tried it, and it seems they’ve selected a more aggressive scheduler for the board, as some benchmarks results are much higher. For example, Vellamo Browser score was over 3,000 today, where as during my initial benchmarks, it only achieved 2,300 points. So quite a boost. Unfortunately, this also introduced so stability issues (possibly resolvable with a heatsink and a fan), and did not improve NTFS performance in a major way:

  1. Multicore benchmarks will make the system reboot. Reproducible with Antutu Multi-thread and Vellamo Multicore tests.
  2. Riptide GP2 game will freeze after a short while. Very similar to what I’ve experienced with some Amlogic S802 TV boxes, except it happens much earlier (after one race).
  3. NTFS write speed is now 4.6MB/s, so it’s still an issue. FAT32 write speed is 29 MB/s, which is fine.

I’ve recorded these three issues in the video below.

So if you are wondering why there aren’t any Allwinner A80 mini PCs just yet, why Cubieboard8 is nowhere to be seen, and why no SDK has been provided for OptimiusBoard and pcDuino8, this could be could the explanation, and more work is needed at this stage of development. The first two issues were not present in the first firmware, but a more aggressive scheduler may have introduced the reboot/freeze issues. I don’t have a spare heatsink/fan, so I haven’t tried to work around these with passive/active cooling. Another possibility for the reboot could be the 5V/3A power adapter does not provide enough power to the board.

Review of Tronsmart Orion R28 Meta 4K/H.265 Android TV Box

October 3rd, 2014 4 comments

It’s been a little while since I unboxed Tronsmart Orion R28 Meta Android TV box, but since the product was still consider “beta” by GeekBuying, I wanted to wait for a OTA firmware update (109k4), which was released at the beginning of the week. Since I’ve already listed the technical specifications, and showed pictures of the board and device, I’ll focus on feature tests and benchmarks results in the review.

First Boot, Settings and First Impressions

I quickly tried the basic infrared remote control, inserting two AAA batteries, and it does the job, but for Android, you really need a pointing device, so I switched to Mele F10 Deluxe air mouse during testing. I’ve connected a whole bunch of cable, and peripherals to the box including an HDMI cable, a USB hard drive, an Ethernet cable, a USB webcam, and a USB hub with RF dongles for my air mouse and gamepad, and USB flash drive. When you connect the power, it won’t start immediately, and just need to press the power button on the device to boot it up. The remote can not turn the box on. Boot time is about 35 seconds, a bit longer than the 20 seconds boot time I experienced in some other Rockchip RK3288 powered media player.

Home Screen (Click for Original Size)

Home Screen (Click for Original Size)

Orion R28 TV boxes only coem with the standard Android home screen, so if you prefer a TV friendly launcher, you’d have to install one from Google Play. The task bar can be shown or hidden with the double arrows icon on the right. The user interface resolution is set to 1920×1080.

The Android settings are pretty standard. Wi-Fi, Bluetooth, Ethernet, and Data Usage menus, as well as a “More” section with VPN, Portable Hotspot, etc… can be accessed in Wireless and Networks section. Display settings include font size adjustment, overscan compensation menu, video output selection (HDMI /  YPbPr / TV), and resolution: “auto”, 1080p 24/25/30/50/60Hz, 720p 50/60, 720×576 or 720×480. If you own a 4K UHD TV, you should also get some extra options up to 4K 60Hz. “TV” mode is composite output, and you can select PAL or NTSC, whereas YPbPr will only support 480p and 720p (no 1080p). “Default Output” (PCM), “Spdif Passthough”, and “HDMI Bitstream” (HDMI pass-through) options are available in the Sound settings (pass-though not tested). The review was done using HDMI output, but I’ve also tried composite and component (YPbPr). Composite output works for PAL and NTSC, but there was the usual green bar at the bottom with NTSC. For once, I managed to make YPbPr work, but only in greyscale (Luminance Y), with the Chrominance signals apparently not outputted..

There are three version for Orion R28: Pro with 8GB flash, Meta for 16GB flash, and the upcoming Telos with 32GB flash. My model is R28 Meta with a 16GB eMMC partitioned into a 1.91GB “Internal Storage” partition for apps, and a 16 GB (black magic alert!) “NAND FLASH” partition for data, with about 11.6 GB available space. I have not checked the free space in the “Internal Storage” partition before thr review, but after installing the applications required for the review, I had just 564 MB available, so some people will want to install custom ROMs to tweak the partition allocation.

The “About device” section includes to OTA updates option: “system updates”, and “wireless update”. You’ll need to click on Wireless Update to install new firmware updated. I’ve done so with upgrading 108k4 firmware to 109k4 firmware. The OTA update did not delete my existing apps and account settings.

Other information include the model number: Tronsmart Orion R28, the Android version: 4.4.2, the kernel version: 3.10.0, and the vendor software version: 109k4. The firmware is already rooted.

I’ll skip the user interface / settings video here, because it’s just the same as other RK3288 TV boxes, minus a custom launcher.

I managed to install most apps via Google Play such as ES File Explorer, MX Player, Antutu, Beach Buggy Blitz, CPU-Z, etc…  Some incompatible apps include Vidonn, Fruit Ninja, and a few others. I’ll also installed Riptide GP2 through Amazon AppStore.

Power Off/standby handling is mostly OK. A short press on the remote/box power button will put the device into standby mode, and by pressing the power button again will make it active. A long press on the power button (remote/box) will pop-up the Android menu with Power Off/Silent Mode, for a proper power off. One annoyance is that you can’t power the device with the remote control, and you need to press the power button on the box itself. If you use Mele F10 Deluxe the power button is the same, and power off work, but I could not go into standby, as the screen would just turn off for one or two seconds before becoming active again. Tronsmart Meta R28 becomes pretty hot, but it’s a common “feature” for all RK3288 boxes. The maximum temperatures measured with an infrared thermometer on the top and bottom of the box were respectively 52°C and 59°C after Antutu, and 57°C and 67°C after playing Riptide GP2 for over 20 minutes.

The firmware is stable and smooth, and I only had one freeze while playing an FLV video in XBMC. I never experienced slowdowns, but boot time, and to a lesser extend app loading is not quite as fast as on HPH NT-V6 or Kingnovel R6, because the eMMC flash read throughput is not quite as high on R28, as we’ll see below.

Video Playback

All other RK3288 devices I tested came either without XBMC, or with XBMC 13 (custom version) pre-install, but Kodi 14-alpha4 came with 109k4 firmware, so it’s interested to see if there are any improvements. The test environment includes an Ubuntu 14.04 server with a SAMBA from which I play videos from Kodi/XBMC, or MX Player in case of issues, over Ethernet.

Let’s start with some videos samples from samplemedia.linaro.org, to which I added H.265/HEVC and VP9 videos:

  • H.264 codec / MP4 container (Big Buck Bunny), 480p/720p/1080p – OK
  • MPEG2 codec / MPG container, 480p/720p/1080p – OK. Some hardly noticeable blinking effect in scenes with grass/trees, but it also happens on my PC, so it could be the original video.
  • MPEG4 codec, AVI container 480p/720p/1080p – OK
  • VC1 codec (WMV), 480p/720p/1080p
    • XBMC – Audio only
    • MX Player – OK (H/W decode)
  • Real Media (RMVB) – RV8, RV9, and RV10 – OK and relatively smooth, but not as perfect as on PC (VideoLAN)
  • WebM / VP8 – OK
  • H.265 codec / MPEG TS container
    • XBMC – 360p and 720p – OK, except seeking does not work. 1080p – many scenes are not smooth, and all 4 CPU cores are maxed out due to software decode.
    • MX Player – OK (H/W decode)
  • VP9 (low resolution) – OK.

This version of Kodi can handle H.265 decode by software up to 720p, MPEG-2 playback seems better, but VC1 videos are still not supported.

Next are some higher bitrate videos:

  • ED_HD.avi – OK, no problem even in fast moving scenes
  • big_buck_bunny_1080p_surround.avi (1080p H.264 – 12 Mbps) – OK.
  • h264_1080p_hp_4.1_40mbps_birds.mkv (40 Mbps) – OK
  • hddvd_demo_17.5Mbps_1080p_VC1.mkv (17.5Mbps) – Audio only (That’s the VC1 codec issue in Kodi).
  • Jellyfish-120-Mbps.mkv (120 Mbps video without audio) – OK

I usually play Jeelyfish-120-Mbps.mkv from a USB hard drive because of the high bitrate, but since Gigabit Ethernet is working fine, that’s the first device that can play it over SAMBA.

High definition audio codec could play (downsampled) in XBMC and MX Player:

  • AC3 – OK (but aspect ratio set to 1:1 is Kodi)
  • Dolby Digital 5.1 / Dolby Digital 7.1 – OK
  • TrueHD 5.1 & 7.1 – OK
  • DTS-MA and DTS-HR – OK

Kodi handled a Blu-ray ISO file (Sintel-Bluray.iso) properly.

Yet again none of my 4K video samples could play successfully in Kodi, with somewhat better results in MX Player:

  • HD.Club-4K-Chimei-inn-60mbps.mp4

    • Kodi – OK most of the time, but skips about 60 frames at the end of the video (The image will freeze before the end of the video).
    • MX Player – Not so smooth, and audio stops well before the video is complete (audio/sync issue?)
  • sintel-2010-4k.mkv
    • Kodi – Many frames dropped.
    • MX Player – Severe decoding issues. Like I see the garbled video in five small screens.
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265)
    • Kodi – Slow motion
    • MX Player – OK (H/W decode)
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265)
    • Kodi – Slow motion
    • MX Player – OK (H/W decode)
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts (H.265)
    • Kodi – Slow motion.
    • MX Player – Plays with S/W decode in slow motion.
  • phfx_4KHD_VP9TestFootage.webm (VP9)
    • Kodi – Won’t start.
    • MX Player – Slow motion (maybe 1 to 3 fps)

Finally, I went through my video library with AVI, MKV, FLV, VOB and MP4 videos. Some FLV video would make the system freeze, requiring an hard reset. At least one video suffered from audio/video sync issues. I could play a  complete 1080p video (1h50) in Kodi, so at least the system appear to be stable, even if many videos can’t be played smoothly. This is not unique to Tronsmart Orion R28 by the way, as other RK3288 boxes are also pretty poor when it comes to video playback.

Network Performance (Wi-Fi and Ethernet)

I’ve now testing both 2.4Ghz Wi-Fi with TP-Link TL-WR940N router, and 5GHz (802.11n/ac) with TP-Link TL-WDR7500 (Archer C7) router. The test consists in transferring a 278 MB file between a SAMBA share and the internal flash, and vice versa. ES File Explorer is used for this purpose, and the test is repeated three times. But before going through the test results, here’s an interesting image…

Tronsmart_Orion_R28_Meta_WiFi_SignalWhereas I get about -49 dB on my phone, the Wi-Fi signal strength in Orion R28 is much lower (-68 dB). As an experiment, I’ve also removed the Wi-Fi antenna in case it was just a bad contact, but it drops to about -82 dB, so there’s another problem somewhere else. That means in Android I only get a “fair” signal, instead of the “excellent” I normally get with other devices in my office, behind just 6 meters (+wall) from the router.

Wi-Fi Throughput in MB/s

Wi-Fi Throughput in MB/s

The weak signal did not seem to affect 802.11n transfer rate, bt may have impacted 802.11ac which ended up being slower than 802.11n… However, I’d expect it to affect range quite a bit, as normally I get signal that weak when I’m in the garden about 15 meters from the router.

At last! An Android mini PC where Gigabit Ethernet works for me! I could transfer a 885 MB file between the internal flash and SAMBA @ about 14 MB/s on average.

Ethernet Throughput in MB/s

Ethernet Throughput in MB/s

Although this test usually works well with Fast Ethernet, the internal storage’s read/write speed will be the bottleneck with Gigabit Ethernet transfer, so transferring from SAMBA to flash is significantly slower (11.8MB/s) than from flash to SAMBA (19.66 MB/s), and even more so from USB HDD to SAMBA (28.5 MB/s), yet it gives an idea of actual file transfer performance between the network on the device.

In order to  get a true estimate of Gigabit Ethernet performance,  I used iPerf app and iperf in my Ubuntu PC, using “iperf -t 60 -c 192.168.0.104 -d” command line in Android. Gigabit Ethernet first, followed by Fast Ethernet:

Client connecting to 192.168.0.110, TCP port 5001
 TCP window size:  425 KByte (default)
 ------------------------------------------------------------
 [  6] local 192.168.0.104 port 58157 connected with 192.168.0.110 port 5001
 [ ID] Interval       Transfer     Bandwidth
 [  6]  0.0-60.0 sec  5.22 GBytes   747 Mbits/sec
 [  4]  0.0-60.0 sec  5.74 GBytes   822 Mbits/sec
 [  5] local 192.168.0.104 port 5001 connected with 192.168.0.110 port 37834
 ------------------------------------------------------------
 Client connecting to 192.168.0.110, TCP port 5001

 [  6]  0.0-60.0 sec   655 MBytes  91.6 Mbits/sec
 [  5]  0.0-60.1 sec   661 MBytes  92.4 Mbits/sec

Fast Ethernet performance is excellent, very close to the theoretical 100 Mbps achievable, and I’d assume Gigabit Ethernet performance will please most people with 747 Mbps and 822 Mbps.

Miscellaneous Tests

Bluetooth

Bluetooth transfer from phone to Android media player is working fine.

The device is rooted, and I could confirm my PS3 Bluetooth gamepad clone is properly recognized with Sixazis Compatibility Checker.

However, I failed to connect to my Vidonn X5 activity tracker, so it could mean Bluetooth Low Energy (Smart) is not working.

Storage

Both a micro SD card and USB flash drive formatted with FAT32 could be automatically mounted and accessed by the systems.
For once, I could see four partitions in ES File Explorer (/mnt/usb_storage/USB_DISK2 directory), but as usual only the FAT32 and NTFS partitions on my USB 3.0 hard drive could be mounted.

File System Read Write
NTFS OK OK
EXT-4 Not mounted Not mounted
FAT32 OK OK
BTRFS Not mounted Not mounted

I benchmarked the NTFS partition (/mnt/usb_storage/USB_DISK2/USB3_NTFS) with A1 SD Bench. Read transfer rate: 27.50 MB/s, write transfer rate: 22.68 MB/s. Both numbers are not that great, but I suppose still acceptable. Orion R28 is on the right on the chart.

Orion_R28_USB_Harddrive

The eMMC flash has a decent write speed (13.58 MB/s), but the read speed (20.19 MB/s) is over half of other competing products based on Rockchip RK3288. The latter will mostly affect boot time, and app loading time during normal use.

Tronsmart_Orion_R28_eMMC_Performance

USB Webcam

I could make a video call with my UVC USB webcam in Skype with both audio and video working, but I had to make a few tries, and Skype hung a few times with Android asking me to kill or wait for Skype to respond.

Google Hangout recognized my webcam, and could make a video call, unfortunately all I got was a black screen. Audio worked however.

Gaming

I played Candy Crush Saga, Beach Buggy Blitz, and Riptide GP2. As usual ran very nicely on RK3288 thanks to the Mali-T764 GPU. I played Candy Crush Saga with Mele F10 Deluxe, and the two racing games with Tronsmart Mars G01 wireless gamepad. Both Beach Buggy Blitz and Riptide GP2 were smooth with maxed out graphics settings, although the latter would benefit from an even faster GPU at times. Temperature measurements after playing Riptide GP2 for over 20 minutes: 57°C (top) and 67°C (bottom).

Tronsmart Orion R28 Meta Benchmark

No surprise here with 36,865 points in Antutu 5.1. It’s slightly faster than NT-V6 because the processor is clocked at 1.8 GHz instead of just 1.6 GHz.

Orion_R28_Meta_Anutut_5.1

Vellamo 3.x scores are just as expected, and comparable to other Rockchip RK3288 mini PCs.

Orion_R28_Meta_Vellamo

Ice Storm Extreme benchmark score (7,513) is about the same as other RK3288 TV boxes, even in the higher range, as these report scores between 7,000 and 7,500+.

Conclusion

Tronsmart Orion R28 Meta comes with a fast processor, excellent 3D graphics performance, and a decent, although not outstanding eMMC. The firmware feels smooth, and I only experience one system freeze in XBMC/Kodi while playing an unsupported video file. It’s also the only Android mini PC where Gigabit Ethernet actually works for me, so this is a big plus, although issue with other models maybe only be due to interoperability problems with my   Gigabit switch. There are also some downside like weak Wi-Fi signal, yet with above average Wi-Fi performance, and video playback needs improvement, especially in XBMC/Kodi, but other Rockchip RK3288 media players have the exact same issues.

PRO:

  • Fast new processor
  • Good platform for games with excellent 3D graphics performance, and support for RF and Bluetooth (PS3) gamepads.
  • Stable and fast firmware.
  • First and only box with working Gigabit Ethernet so far (for me).
  • Video Output – 1080p support 24, 25 ,30 , 50 and 60 Hz output. 4K @ 60Hz should be supported (not tested). Composite is working.
  • Support for OTA update
  • Support forums
  • Proper power off/standby handling.

CONS:

  • Kodi/XBMC has too many issues: VC1 not supported, H.265 only supported by software, audio/video sync issue, few 4K videos could play properly, may hang system, etc…
  • Weak Wi-Fi signal, although performance is OK.
  • Video output – Component does not fully work  (grayscale only)
  • Webcam not working properly (black screen) in Google Hangouts. OK in Skype but the app does not seem very stable.
  • Bluetooth Low Energy may not be working

Tronsmart Orion R28 Meta can be purchased for $119.99 on GeekBuying or Aliexpress, You can also get a cheaper model without 802.11ac support (just 802.11 n/g/n) and only 8GB eMMC, called Orion R28 Pro, for $99.99 on GeekBuying or Aliexpress.

STMicro STM32F4 (Cortex M4) vs STM32F7 (Cortex M7) Graphics Demo

October 2nd, 2014 No comments

STMicro announced their latest STM32F7 micro-controller family based on ARM Cortex M7 last week. As ARM Techcon 2014 is now taking place, the company has uploaded an infomercial on their YouTube account, where STMicro and ARM representatives are interviewed about the new family, and talk about its performance, power consumption, target applications, business prospects, and so on. But there’s also an a short demo with two development kits one with a STM32F4 cortex M4 micro-controller, and the other with a STM32F7 micro-controllers. Since both MCU families are pin-to-pin compatible, the hardware is identical except for the MCU.

Both kits are pre-loaded with a 3D graphics demo (ray tracer), and the board with STM32F7 completes the demo in about half the time of the one with STM32F439, allegedly with about the same power consumption (7 coremarks / mW). The video is about 8 minutes long, and the demo starts at 1:25.

STMicro is only working with selected partners for now, and full mass production is scheduled for early Q2 2015.

Review of Nagrace HPH NT-V6 Android Mini PC Powered by RK3288 with 4GB RAM, 32GB Internal Storage

September 30th, 2014 8 comments

Last week-end, I finally received TP-Link TL-WDR7500 router (Chinese variant of Arched C7) router, so I could complete my review of Nagrace HPH NT-V6 including 802.11ac Wi-Fi. I’ve already listed the specifications, and taken a few pictures of the device and the board, and today I’ll focus on the test results. I’ll start by giving my first impressions, going through the user interface and settings, before testing video playback, as well as benchmarking networking, storage and overall system performance, playing some games, and testing most hardware features of this mini PC.

First Boot, Settings and First Impressions

A simple infrared remote control is provided with the device, and I’ve quickly tried it by inserting two AAA batteries, and it works fine, but for the rest of testing I switched to Mele F10 Deluxe air mouse to control the device, as it’s much more user friendly than any IR remote. Before booting up the device, I’ve connected an HDMI cable, a USB hard drive, an Ethernet cable, a USB webcam, and a USB hub with RF dongles for my air mouse and gamepad, and USB flash drive. Finally connect the power supply to boot the device in about 20 seconds.

NT-V6 User Interface (Click to Enlarge)

NT-V6 User Interface (Click to Enlarge)

The company has made their user interface, but in a similar style than the one common found in Amlogic S802 devices. On the top right, you’ve network status (Wi-Fi, Ethernet, and Bluetooth). The status bar won’t show in the main menu, but in some other apps and settings, you’ll be able to access it. A large section with 9 folders can be found on the left with Movie (Videoplayer), XBMC (yes a folder too containing XBMC, so you have to click twice), Music, Game, Browser, Stream (Youtube and Netflix), Screencast, Social and Market. On the right, you’ve got the time, and weather (that does not work), and four more icons: “My Device” (Actually a file manager), “All Apps”, “Settings”, and “All Tasks Killer”. The user interface resolution is set to 1920×1080.

The Android settings are very similar to other RK3288 TV box. The Wireless and Networks menu comes with Wi-Fi, Bluetooth, Ethernet, and Data Usage sections, as well as a “More” section with VPN, Portable Hotspot, etc… Display settings let you set the font size, adjust the screen size, select between HDMI, YPbPr (Component), and “TV” (Composite) video outputs, and the resolution: “auto”, 1080p 24/25/30/50/60Hz, 720p 50/60, 720×576 or 720×480. I don’t own a 4K UHD TV, but if I did, there should also be some 4K options. You can choose between “Default Output” (PCM), “Spdif Passthough”, and “HDMI Bitstream” (HDMI pass-through) in the Sound settings. HDMI video output is working, but composite and component (YPbPr) video outputs failed to work. An AV cable was not included, so I used some other cables, and I could only see a black screen. Audio (L/R) works fine.

What about HDMI In? I’ve connected Orino R28 meta to the HDMI input port of the NT-V6, clicked on HDMI IN app, and I could see R28 user interface, but apart from that I could not do much. Things like Android notifications of the “host” won’t show up, as as it stands the HDMI In function is just like a cheap HDMI switcher. To go back to main user interface, simply press the back key on the remote.

The version of HPH NT-V6 I got comes with a 32GB eMMC, other options includes 8, 16 or 64 GB, which is partitioned into a 1.91GB “Internal Storage” partition for apps, and a 25.99 GB “NAND FLASH” partition for data. After I installed all applications I needed for this review, I was left with 568 MB available. It would have been preferable to design the system with a single flash partition, or make the “Internal Storage” a bit bigger. Nevertheless with 26 GB for data, there’s plenty of data, even to download and place movies directly from eMMC flash.

The “About device” section only lists the model number (HPH-F0-N6) and the Android version (4.4.2). It’s running on top of Linux kernel 3.10.0, but it’s not indicated in this section. The firmware is not rooted, and NT-V6 is another device with a USB A receptacle, instead of a micro USB port, and I could not root it via the OTG port since I don’t have a proper cable. There’s a System Update app for OTA firmware upgrades, and the firmware version is currently 1.1.9 in my device. I’m not 100% sure it works, because I have not received a firmware upgrade yet.

In the video below, I boot the device, and go though the user interface, and system settings.

Google Play Store mostly works. I could install most apps, install a paid app, such as ES File Explorer, MX Player, Antutu, Beach Buggy Blitz, CPU-Z, etc…  Vidonn activity tracker app was reported as “incompatible with your device”. I discover an easy way to quickly scan through compatible apps that you’ve installed in other devices previously with the same account. Go to My Apps->All in the Play Store, and you can scroll down to see which apps are already installed, or incompatible. You can also select multiple apps, and click Install for bulk installation. Since I got Riptide GP2 as a “free app of the day”, I installed Amazon AppStore to install the game.

Power control work as it should. A short press on the remote will put the device in standby mode, and you start it again but pressing the remote button again. A long press on the power button will pop-up the Android menu with Power Off/Airplane Mode/Silent Mode, in order to achieve true power off. A press on the box button will have the same effect. When the device is powered off, you can press the remote power button, or the power button on the media player, although I’ve found the latter does not always work… It takes 3 to 4 second for power LED to run blue after pressing the power button, so it’s a bit confusing at times. and you need to wait 4 seconds to make sure you’ve really powered the device on. Both the included remote control and Mele F10 Deluxe could power on/off NT-V6. As with other RK3288 devices, the case may become hot. After Antutu benchmark, the maximum temperatures measured with an infrared thermometer on the top and bottom of the box were respectively 58°C and 64°C, and 58°C and 66°C after playing Riptide GP2 for over 20 minutes.

HPH NT-V6 mini PC is very stable, and I never had a reboot and hang up during my 6-8 hours testing. Boot time (20s) and XBMC load time (2s) are very similar to Kingnovel R6 as both integrate a fast eMMC flash.

Video Playback

Video playback results are the same as Kingnovel R6 (previously known as K-R68), so I invite you to visit R6 review for video testing. To summarize, a version of XMBC 13 alpha12 is pre-installed, and suffers from not-so-smooth MPEG2 playback (in some files), lack of support for VC1, some 4K videos are not smooth at all, as well as audio/sync issues.

What’s different however is that I could play some HEVC/H.265 videos in XBMC:

  • H.265 codec / MPEG TS container (Elecard 360p / 720p / 1080p) – Audio only
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 – OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 – OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts – Won’t start to play

I’ve also test some VP9 videos. They can’t be played in XBMC, but can in MX Player:

  • out9.webm (low resolution) – OK. H/W decode according to MX Player.
  • phfx_4KHD_VP9TestFootage.webm (3840×2160) – Maybe 1 or 2 frames per second, still with H/W decode according to MX Player, but internally it’s certainly using S/W decode.

I also played a complete FullHD video (1h50) with XBMC to test stability. I had the same slow XBMC exit as with other boxes, which does not happen all the time, and apparently only during scanning or other background tasks.

Links to various video samples used in this review and be found in “Where to get video, audio and images samples” post and comments.

Network Performance (Wi-Fi and Ethernet)

To evaluate network performance, I transfer a 278 MB file between a SAMBA share and the internal flash, and vice versa, using ES File Explorer, and repeating the test three times. I now have two routers, but I’ll keep testing 2.4GHz Wi-Fi with my old TP-Link TL-WR940N router, and test 5GHz Wi-Fi with TP-Link TL-WDR7500 (Archer C7) which also support 802.11ac. I already tested NT-V6 in TL-WDR7500 review, and found the connected with NT-V6 to be unstable, and not that fast. That was on Sunday… But on Monday I tested it again, and the performance and stability was much better. I have no idea why. The only differences are: it was raining on Monday, and I was the only  one using Wi-Fi, whereas on week-ends, TL-WR940N may get 4 to 5 connected clients. So it went from 1.92 MB/s to 3.91 MB/s average speed with 802.11n, and 3.02MB/s  to 4.85 MB/s with 802.11ac, the best performance I ever got with Wi-Fi.

Throughput in MB/s

Throughput in MB/s

The top line is with 802.11ac, and the second line with 802.11n @ 2.4GHz. But as I said this chart may overestimate the actual Wi-Fi capabilities of NT-V6, and performance seem irregular… Using “sunday” results, 802.11ac would have been in third position in the chart, and 802.11n between Vega S89 and VidOn.me AV200.

And now Ethernet…. I had rather disappointing performance with Fast Ethernet, and still more problems with Gigabit Ethernet… I should really buy another Gigabit switch to make sure that’s not the root cause.

Fast Ethernet Performance in MB/s

Fast Ethernet Performance in MB/s

I could actually get a Gigabit Ethernet connection, but I got a transfer rate of 250 KB/s from network to flash, and 1.8MB/s from flash to network…

In order to get a “pure” network test, I also used iPerf app and iperf in my Ubuntu PC, using “iperf -t 60 -c 192.168.0.104 -d” command line in Android. It clearly show some issues with both Fast and Gigabit Ethernet, and whereas one direction has good performance, the other is problematic (100Mbps first, then Gigabit):

Miscellaneous Tests

Bluetooth

File transfer over Bluetooth works fine. I use ThL W200 Android smartphone to send a picture to NT-V6.

I skipped Sixaxis test for PS3 Bluetooth Gamepad support, because the firmware is not rooted, and I’m not sure how to root it without OTG cable.

Vidonn X5 activity tracker was used to test Bluetooth 4.0 LE. I could not install Vidonn app from Google Play (incompatible), so I instead installed vidonn.apk, and successfully connected to my wristband to get the data. Note-to-self: make sure to set the time on the mini PC before making the connection to the wristband, or it will mess with the data…

Storage

The system could detect and mounted a micro SD card and USB flash drive formatted with FAT32.
It seems nobody is interested in having EXT-3/4 working for external storage in Android, and as usual only the NTFS and FAT32 partitions on my USB 3.0 hard drive could be mounted.

File System Read Write
NTFS OK OK
EXT-4 Not mounted Not mounted
FAT32 OK OK
BTRFS Not mounted Not mounted

I benchmarked the eMMC and the NTFS partition on my hard drive with A1 SD Bench. There does not seem to be a standard for mount points in Android, and firmware from various (SoC) vendors, have different mount points. In this firmware, the NTFS partition is located in /mnt/usb_storage/USB_DISK2/USB3_NTFS. The read speed was 35.62MB/s, and the write speed of 15.08MB/s, so NT-V6 gets both the best read speed, and the worst write speed of all devices I tested.

USB NTFS Performance in MB/s

Hopefully, the only solution is some optimization for NTFS writing speed.

The Samsung eMMC found on the board has very good performance, reading at 55 MB/s, and writing at 18 MB/s.

Beside fast loading times, a product with a fast eMMC is much less likely to experience slowdowns.

USB Webcam

I could test audio successfully with the Echo service in Skype, but unfortunately although my webcam appeared to be detected in both Skype and Google Hangouts, I could only see a black screen during video calls.

Gaming

Candy Crush Saga, Beach Buggy Blitz, and Riptide GP2 all worked pretty well. I played Candy Crush Saga with Mele F10 Deluxe, and the two racing games with Tronsmart Mars G01 wireless gamepad. Beach Buggy Blitz is super smooth all the time, even after maxing out graphics settings. Riptide GP2 is very playable as well, but not optimal all the time, but clearly mini PCs based on Rockchip RK3288, and much better than the rest of Chinese Android mini PCs thanks to its Mali T-764 GPU. I played the latter game for over 20 minutes to test stability, and I did not encounter any specific issues. Temperature measurements after game: 58°C (top) and 66°C (bottom).

Nagrace HPH NT-V6 Benchmark

CPU-Z app returns similar data as other TV boxes with Rockchip RK3288 processor being a four Cortex A12r0p1 core processor with a Mali-T764 GPU, except this time, the CPU frequency is between 312 MHz and 1.61 GHz, instead of topping at 1.8GHz for other devices.. I could also check there’s indeed 4GB RAM installed with over 2700 MB free.HPH_NT-V6_CPU-Z

NT-V6 could achieve G1H got 35,321 points in Antutu 5.1, a bit lower than Kingnovel R6 score (37,428), most probably because of the lower CPU frequency.

I had not run Vellamo 3.x  test in R6 media player, but the scores in NT-V6 are better than the ones for Uyesee G1H.

Ice Storm Extreme benchmark score (7,056) in 3DMark is however a bit lower than the two other RK3288 box I tested (7,278 and 7,531).

Conclusion

Nagrace HPH NT-V6 is a pretty good hardware with a fast processor, excellent 3D and eMMC storage performance. The firmware is stable, and provides a smooth user experience, without slowdowns. Wi-Fi can be excellent too, but stability may be an issue. As with other Rockchip RK3288 devices I’ve tested,  video playback in XBMC is rather disappointing, but at least there’s partial HEVC/H.265 codec support. partial, nbecause only some caontainers appear to be supported.

PRO:

  • Fast new processor
  • Excellent 3D graphics performance for games
  • Stable and fast firmware.
  • Memory and Storage capacity (4GB / 32GB)
  • Excellent Wi-Fi performance, when it works
  • Fast eMMC, both for reading and writing speeds.
  • Both 720p and 1080p user interfaces are supported
  • Video Output – 1080p support 24, 25 ,30 , 50 and 60 Hz output. 4K @ 60Hz should be supported (not tested).
  • Partial HEVC/H.265 video decoding support in XBMC.
  • OTA update appear to be support
  • Proper power off/standby handling.
  • HDMI In

CONS:

  • XBMC has too many issues: VC1 not supported, H.265 support only partial, audio/video sync issue, some MPEG-2 and XVID videos are skipping frames, some of the 4K videos I used could play properly, etc…
  • Some MPEG-2 file won’t play smooth in either XBMC or MX Player
  • Potential Ethernet issues, confirmed with my Gigabit switch (D-Link DSG-1005A) and 10/100Mbps D-Link router (configured as a switch).
  • Video output – Component and composite do not work atall (black screen)
  • Webcam not working properly (black screen) in Skype and Hangouts
  • Relatively slow write speed on NTFS/USB partition.
  • Wi-Fi may be unstable at times
  • HDMI In support is quite basic (only as HDMI switcher)

HPH NT-V6 with 4 GB RAM and 32 GB eMMC (as reviewed in this post) purchased for $189 including shipping by DHL or EMS, but there’s also a 2GB RAM/16GB eMMC available on Aliexpress for $129 + shipping. I’ve also been told Ugoos UT3 is based on the same board (TRN6A), but should have a different firmware. It is listed on Chinavasion for $149.99, and DealsPrime for $134.99 (bot 2GB/16GB versions). Resellers and distributors can check out Nagrace NT-V6 product page to order in quantities.
