Rockchip RK3288 To Be Phased Out Soon? GPD XD+ Android Console To Get Mediatek MT8176 SoC, 4GB RAM Upgrade

December 7th, 2017 22 comments

[Update: I have now seen an email exchange with ASUS replying that Rockchip RK3288 will still be in production for 5 years, so GPD claims that manufacturing will stop for RK3288 may be incorrect, or misunderstood

Update 2: Rockchip has now confirmed RK3288 will not be phased out. So I’m guessing there may have been info lost in translation with GPD simply not manufacturing their own RK3288 board anymore]

Rockchip RK3288 32-bit Arm processor was first spotted in a company presentation in the summer of 2013, before being announced – with some confusion (Cortex A12 vs A17) – at CES 2014 in January. The quad core Cortex A17 processor had then its moments of glory with inclusion in products such as Chromebooks (2015), and ASUS Tinker board SBC earlier this year.

Another product based on the processor is GPD XD Android game console, but according to a report on reddit, GPD will soon launch an upgraded version call XD+ powered by Mediatek MT8176 Hexa-core Cortex A72/A53 processor with 4GB RAM, mainly because “Rockchip are phasing out sales of the RK3288”. If true, it means most products based on the chip will soon be phased out or upgraded to another solution. How long each product will keep selling will depend on the stocks held by the manufacturer.

GPD XD+ console preliminary specifications:

  • SoC – Mediatek MT8176 hexa-core processor with 2x Cortex A72 cores @ 2.1 GHz, 4x Cortex A53 cores @ 1.7 GHz, and Imagination PowerVR GX6250 GPU (as used in Xiaomi Mi Pad 3 tablet)
  • System Memory – 4GB RAM
  • Storage – 32GB and up internal storage, micro SD slot
  • Display – 5″ 720p capacitive touch display
  • Video Output – 1x mini HDMI
  • Audio – Dual speaker, via HDMI output, 1x 3.5mm audio jack
  • Connectivity – Dual band WiFi, Bluetooth
  • USB – 1x micro USB port
  • Buttons – Power button, cross button, dual-character button(A/B/X/Y;△/○/×/□), L1/L2/L3/R1/R2/R3, joysticks, Start/Select button, Volume +/-, Back,Android function, Home, Keymapper button
  • Sensor – 3-axis gravity sensor
  • Battery – TBD
  • Power Supply – TBD
  • Dimensions – 155 x 89 x 24 mm
  • Weight – ~300 grams

The device will run Android 7.x, and as you’ll see from the video below some people already got prototypes, with the device achieving 74,500 points in Antutu 6, and a the following Geekbench scores: Single core: 1375; multi core 3529.

The physical aspect of XD+ looks exactly the same as XD, but performance should be quite better with the Cortex A72 cores and PowerVR GPU in the Mediatek SoC, and some games did run better on the new model in the video above. Some games also only work with 64-bit Arm, so more games will be supported.

GPD XD+ is expected to start selling in Q1 2018 with some resellers mentioning January, while other telling the February-March timeframe is more likely. It will all depend on results of testing of the beta units, and other potential production delays.

I contacted Rockchip to try to get more information about the timeline of RK3288 end-of-life status, but I did not get an answer in time for this article. I’ll update it if I get an answer.

Mediatek MT2621 Supports Dual Mode NB-IoT and GSM/GPRS for IoT, Wearables, and Industry 4.0

December 1st, 2017 5 comments

Mediatek introduced MT2625 ARM Cortex-M SoC supporting NB-IoT (aka LTE Cat NB1/NB2) compatible with 3GPP Release 14 last summer, and designed for global cellular IoT devices.

The company has now unveiled a new NB-IoT part with Mediatek MT2621 ARM7 dual-mode IoT SoC that is capable of both NB-IoT R14 and GSM/GPRS connectivity for applications such as smart trackers, wearables, IoT security, smart metering and industrial applications. The chip would allow you to start deploying devices with GSM connectivity, and once available in your locale, switch to the more efficient NB-IoT protocol.

Mediatek MT2621 specifications:

  • Processor – Single ARM7 core @ up to 260MHz
  • Memory – 160KB + 4MB PSRAM
  • Internal Flash
  • Connectivity
    • Integrated Baseband, RF, Antenna, and Modem DSP
    • NB-IoT ultra-low/low/mid bands defined by 3GPP Rel-14
    • GSM/GPRS
    • Bluetooth 4.2
  • Display – LCM interface
  • Camera – Camera interface
  • Audio – Audio Amplifier
  • Integrated PMU

Mediatek is really light on details, but still confirms a single SIM and antenna covers both cellular networks (NB-IoT & GSM) with dual standby functionality (SSDS). This will allows a single UICC and mobile number for both networks, “saving PCB space, simplifying design, minimizing cost and speeding time-to-market”.  The company also claims “applications can be built using an easily customizable Linux-based OS”.

Mediatek Helio X20 vs Qualcomm Snapdragon 625 – 3D Graphics Benchmarks and CSR2 Game

October 17th, 2017 4 comments

I’ve been using Vernee Apollo Lite smartphone with a Mediatek Helio X20 deca-core ARM Cortex A72/A53 processor coupled with an ARM for a little over a year. Recently, I’ve received Xiaomi Mi A1 smartphone for a Qualcomm Snapdragon 625 SoC featuring eight ARM Cortex A53 cores and an Adreno 506 GPU.

In theory, the latter is a downgrade, and the Xiaomi phone is indeed quite slower in Antutu with overall score of 60,161 points against 85,840 points in the Mediatek phone. 3D graphics performance is also lower with 12,849 vs 17,828 points. Both smartphone have the same resolution (1920×1080), so it’s a little confusing to be told you’d “better to play games in low quality mode” for the Mediatek phone, and “game performance is mid-level” for the Snapdragon one.

But anyway Helio 20 should work better in 3D games than Snapdragon 625 if we are to believe the numbers. Most apps run fine on Vernee Apollo Lite, but one game I play is sometimes extremely sluggish, especially in a specific section of the user interface. That game is CSR Racing 2 (aka CSR2), and the section is called “Rare import” where the game will sometimes freeze for a few seconds apparently while rendering some animations. The phone may also overheat while playing, and I’ve used Boots hot & cold pack a few times to keep it cool and make the game playable, but that’s another story 🙂

So I was interesting to find out if CSR2 would also freeze in Xiaomi Mi 2, and see how it performs while actually playing, so I placed both phones side-by-side to check it out.

The video above does not actually show the worst case for the Mediatek processor, as sometimes the animations in “rare imports” would freeze for 3 to 4 seconds and several times during the process. So far, Xiaomi Mi A1 has been working very well in that section. In the video I mentioned that I could not see much difference between the two phones during playback, but after playing further I found the Xiaomi Mi A1 is also smoother to play. After also double-checking the video, it’s also clear there are less texture details and fewer objects shown in the Snapdragon 625 phone, as shown in the photo below with trees shown in Vernee Apollo Lite, but not the Xiaomi phone.

The app is likely auto-detecting the phone performance, and it works well for one, and not quite as well for the other. It’s also possible the developers focus on the most popular phones from Samsung, Motorola, HTC, and other brands which are usually equipped with Exynos or Snapdragon processors, rather than Mediatek ones. I could not find an option to manually adjust the image quality/resolution in the game.

The conclusion is that you can’t simply look at benchmarks to find out if a particular game will work well on your phone. In this case Helio X20 is closed to 40% faster in Antutu 3D GPU benchmark, but the user experience is much better with the Snapdragon 625 phone, albeit at the cost of a little less graphics details. Other games will likely differ depending on the implementation.
