Nvidia Tegra X1 Gets About 75,000 Points in Antutu

February 19th, 2015 5 comments

Nvidia Tegra X1 was expected to outperform the competition, but based on Antutu results provided by Mydrivers, the performance leap might be greater than expected, as Nvidia Tegra X1 reference tablet gets 74,997 points in Antutu 5.6.1.
Tegra_X1_AntutuAs usual caution is warranted with Antutu results, as the benchmark is easily cheated, which explains why Allwinner A80T devices can get over 140,000 points. But let’s assume Tegra X1 result is representative and compare it to its predecessor the Tegra K1. Surprisingly I struggled to find a detailed Antutu 5.x score for the Nexus 9, and I had to get the scores from that video with Antutu 5.2.0.

Nexus 9
(Tegra K1 64-bit)

Tegra X1
Reference Platform

Ratio
Antutu 57040 74977 1.31x
Multitask 11817 9217 0.78x
Runtime 4146 4758 1.15x
CPU integer 3038 11295 3.72x
CPU float-point 1939 7274 3.75x
Single-thread integer 2920 3206 1.10x
Single-thread float-point 2831 2878 1.02x
RAM operations 1424 4353 3.06x
RAM speed 4926 5920 1.20x
2D graphics 702 1705 2.43x
3D graphics* 20032 21093 1.05x
Storage I/O 2500 2586 1.03x
Database I/O 735 712 0.97x

* Resolution for Nexus 9: 2048×1536; resolutions for X1 reference platform: 3840×2160.

After completing this table, I’ve just noticed some other people got 34,000 points on the Nexus 9, still with Antutu 5.2.0. Let’s us just hope Antutu gets obsoleted very soon. Having said that the results don’t see so unrealistic with 30% improvement over Tegra K1 64-bit. Multicore tests provide a much higher score thanks to the eight ARMv8 cores in X1 vs the two ARMv8 cores in K1. CPU clock is unknown for X1since Antutu stopped reporting it. RAM “operations” are three times faster on X1 too, whatever that means, which the speed is about 20% faster. 3D graphics should be much better on X1 thanks to its 256-core Maxwell GPU, but the difference is not that great, because of the higher resolution used for X1 hardware, so the total score would certainly be higher if X1 was connected to a 2048×1536 display.

Winbook TW700 Windows 8.1 Tablet with micro HDMI, Full Size USB Port Sells for $60

February 5th, 2015 12 comments

MeegoPad T01, Pipo X7, MeLE PCG03, MINIX NEO Z64, etc.. you could name a pretty long list of Intel Bay Trail-T Z3735 mini PCs running Windows 8.1… They all cost above $100, but the ones that include a valid Windows 8.1 license usually cost closer to $150. That’s because contrary to the Windows 8.1 with Bing on small tablets that comes free and with a one-year subscription to office 365, Windows 8.1 with Bing on mini PCs adds about $30 to the price, and it does not even include a one-year subscription. So using a tablet as a mini PC should be cheaper, even with the extra touchscreen display and battery. And as I checked out Liliputing’s list of cheap Windows tablets, Winbook TW700 stood out as it sells for just $60 on Micro-center (US only) or $70 on Amazon US, and features a mini HDMI port, a full-sized USB port, meaning it can easily be connected to an HDMI TV, and be used as mini PC for over half the price of actual Windows 8.1 mini PCs.

Winbook_TW700Winbook TW700 specifications:

  • SoC – Intel Atom Z3735G “Bay Trail” quad core processor @ 1.33 GHz (Bust freq: 1.83 GHz) with Intel HD graphics (2.2W TDP)
  • System Memory – 1 GB DDR3
  • Storage – 16 GB eMMC + micro SD card slot (up to 64 GB)
  • Display – 7″ IPS display; 1280×800 resolution; 5-point touchscreen
  • Video Output – micro HDMI
  • Audio I/O – micro HDMI, 3.5mm earphone jack
  • Connectivity – 802.11 b/g/n Wi-Fi, and Bluetooth 4.0
  • USB – 1x USB 2.0 host port, 1x micro USB OTG port
  • Camera – 2MP Front-facing and rear cameras
  • Sensors – G-sensor, light sensor
  • Misc – Power and volume buttons
  • Battery – Rechargeable lithium-on battery (Capacity not specified)
  • Power Supply – 5V/2A
  • Dimensions – 189 x 121 x 11 mm
  • Weight – 350 grams

So the memory and storage are a bit tight, but it should probably be enough to run Kodi 14 with the default skin, and should make a very good media player based on my Kodi 14.1 testing with MeLE PCG03, providing a smoother experience than on any ARM based mini PC I tried in the past, as long as you play videos up to 1080p, and don’t need HEVC/H.265 video decode. Some people also noticed an overheating issue on other devices while playing high framerate videos (50 fps @ 720p or 1080i), leading to throttling on Pipo X7, but I could not reproduce this in MeLE PCG03. It mostly depends on the thermal design of the device, and one person also said running Kodi in Linux does not exhibit the issue, but requires a USB sound card, as HDMI audio does not work (yet). Hopefully a working OpenELEC image will soon be released for Intel Atom Z37xx devices.

One other difference is the use of Z3735G instead of Z3735F, which means the maximum memory is 1GB RAM, and the memory bandwidth is only 5.3 GB/s instead of 10.6 GB/s.

As I understand it, Winbook is a US brand and only sells in the US, so if Amazon US won’t ship to your country, you’re out of luck. But as the device is certainly a re-branded Chinese table, so I checked out for similar Z3735G tablet on Aliexpress. I could not find an exact match, but PiPo W7 and Cube iWork7 tablets are selling for about $80 including shipping, and both include micro HDMI and micro USB OTG ports, but no full-size USB port.

Meet the First Nvidia Tegra X1 “Tablet”: Nabi Big Tab XL

January 8th, 2015 No comments

Nvidia announced their latest Tegra X1 processor at CES 2015 earlier this week, and after showcasing it’s computing and power-saving capabilities, the company focus on its applications: automotive dashboard and driverless cars. Nothing about tablets, or gaming consoles, probably because these two are more cost sensitive than the automotive market. But finally, we’ll see at least one tablet powered by TX1: Nabi Big Tabs. I say “tablet”, but at 55″ to 65″, it’s more like a TV with a touchscreen…

Tegra_X1_TabletFuhu actually announced four TV sized Big Tab XL tablets. The “small” ones with 32″ and 42″ FullHD displays come with a Tegra K1, while the larger ones (55″ and 65″ / 4K UHD) are powered by a Tegra X1 processor.

Here are some of the specs for the tablets:

  • SoC
    • Nvidia Tegra K1 quad-core Cortex A15 processor @ 2.3GHz with 192-core Kepler GPU or
    • Nvidia Tegra X1 octa-core Cortex A57/A53 processor with 256-core Maxwell GPU
  • System Memory – 2GB (K1) or 4GB (X1) RAM
  • Storage – N/A
  • Display
    • 32″ or 42″ Full HD (1080p) touchscreen display
    • 55″ or 65″ 4K UHD (2160p) touchscreen display with 20 to 40 touchpoints.  (Yes, that’s 4 to 8 hands!)
  • Video Input – 2 or 3 HDMI inputs
  • Audio – Front ported speaker chamber
  • Connectivity – WiFi, Bluetooth, NFC
  • USB – A few USB ports on the side
  • Dimensions – Very large
  • Weight – Very heavy

Nabi_Big_Tab_XL The demo model at CES 2015 is running Android 4.4, but the retail version will features Android 5.0 instead. In case the picture above did not provide enough clues, these are marketed as kids tablet, and the company’s Blue Morpho OS with over 400 games, educational and artistic apps help achieve this goal. It will be fun to see apps supporting 8 hands…

Fuhu’s large tablets are expected for Q4 2015. Prices have not been disclosed yet, but should be slightly above equivalent televisions.

AllWinner A64 is a $5 Quad Core 64-bit ARM Cortex A53 SoC for Tablets

January 8th, 2015 8 comments

Allwinner already announced H64 octa-core Cortex A53 processor for OTT boxes together with Nobel64 development board in the last quarter of last year, and the Chinese silicon manufacturer has now introduced Allwinner A64 quad core Cortex A53 processor for entry-level tablets, as the processor will only cost $5 per unit in large quantities.

Allwinner_A64As usual, Allwinner only provided a subset of information for their first announcement, and some technical details like the GPU are unknown.

Key features listed for Allwinner A64:

  • 64-bit Cortex-A53 architecture
  • Supports H.265/H.264 video decoding in hardware, and supports HDMI 4K display
  • Supports various DDR memory types, making the BOM cost more competitive
  • Supports eMMC 5.0 for better IO performance and enhanced data throughput capacity
  • Allwinner SmartColor display technology for more vivid and eye-pleasing visual experience
  • Supports Trusted Firmware security architecture from ARM

The company is finally moving to a device tree enabled kernel with Linux 3.10, and Allwinner 64-bit ARM tablets will also run Android 5.0 Lollipop. Hopefully, this processor implements proper H.265 hardware decoding, not GPU accelerated decoding as in Allwinner A80 processor. Interestingly neither Allwinner A64, nor Rockchip RK3368 announced recently, support VP9, despite it being the codec of choice for YouTube 2160p content.

Rockchip Introduces RK3368 Octa Core Cortex A53 SoC for Tablets and 4K TV Box

January 7th, 2015 7 comments

Rockchip is also at CES 2015, and they’ve announced and are showcasing a new octa-core processor called RK3368 with eight 64-bit ARM Cortex A53 cores that will go into tablets and 4K UHD media players in the coming year. Most news outlet and blogs at CES only cover big brand, so all I got are a few tweets from Rockchip twitter account.

Rockchip_RK3368The eight cores will be clocked up to 1.5 GHz, and the SoC includes an unnamed GPU with support for OpenGL ES 3.1, OpneCL 1.2 and DirectX 9.3. 4Kx2K H.265 and H.264 video decoding will be handled by the chip too, as will out HDMI 2.0 for up to 2160p @ 60 Hz video output.

RK3368_Reference_Platform

RK3368 tablets and media players will run Android 5.0 Lollipop. RK3368 is probably the official name for MayBach processor.

I’m now fully relying on Charbax to get more details about Rockchip new processor… :)

[Update: Liliputing shot a video with RK3368 Reference Tablet.
