AllWinner UltraOcta A80 is said to achieve 41556 in Antutu showing it easily outperform Exynos 5420 Octa core processor found in Galaxy Note 3, but this result has been achieved with a development board featuring heatsink and fan, so it’s unlikely you’ll get such score in your AllWinner A80 based tablet and TV box.

In the video below, you see some demos with real-time 4K video decoding/encoding with a 16MP pixel and 4K TV, HEVC video playback, 3D face rendering to show off GC6230 GPU performance, and a network video recording demo that can be used in automotive applications. You’ll also a reference tablet, and some charts showing the performance / power consumption ratio.

There are some good news about the OptimusBoard as it should be available in May for less than $100 via Cubieboard and/or PcDuino teams. Android tablets will be available by the end of May, and TV boxes a little latter.

Vivante Unveils Details About GC7000 Series GPU IP Family

April 19th, 2014 8 comments

Earlier this month, Vivante Corporation has announced several silicon partner integrations (but no names given) of its GC7000 Series GPU IP into SoCs targeting wearables, mobile, automotive, and 4K TV products, and provided some more details about its GC7000 family which supports features such as OpenGL ES 3.1 API, and hardware TS/GS/CS (tessellation / geometry / compute shader) extensions for Android.

Vivante_GC7000_Architecture

According to the company, they key benefits of their GC7000 GPU IP can be summarized as follows:

  • True GPU Scalability – GC7000 Series products support limited silicon area to match form factor and market requirements. Products can snap to grid starting at 3.0 mm2 (28 nm) for the smallest single GPU GC7000 instance and grow in simple modular fashion for high end implementations to achieve what the company’s claims to be the the industry’s best PPA (power/performance/area).
  • Smallest Licensable OpenGL ES 3.1 Cores with Geometry, Tessellation, and Compute Shaders - Die area of the GC7000 is reduced by 20% over previous generation mass market cores and includes the new evolution of OpenGL ES 3.1 and DirectX 11 shader/GPU technologies and upcoming mobile platform requirements, including support for hardware TS/GS shading extensions for Android OS.
  • Faster Graphics Performance - Better real time utilization of shaders speeds up rendering performance, quality and effects to effectively scale up for 4K gaming content at 60 FPS.
  • Cooler Cores – GPU thermals and system power are reduced 30% and bandwidth is reduced by 50% through bandwidth modulation using Vivante frame buffer (vFB) and pixel compression, Khronos ASTC, geometry/tessellation shader rendering, and Android optimized intelligent composition (Regionizer).
  • Configurable Shader Core Implementations – Cores range from highly silicon optimized eight shader solutions to performance optimized multi-GPU/multi-shader solutions, all with hardware support for security (secure GPU) and OS virtualization.
  • Hardware and Software Integration Simplified – The single unified software stack supports all Vivante GPU cores and existing software platforms to create a seamless transition to the latest technologies. GC7000 hardware is even more modular to allow faster integration with easier place-and-route design and reduced wire congestion.
  • System Friendly Architecture – GC7000 is designed for hybrid and heterogeneous computing systems supporting OpenCL and HSA using AMBA ACE-Lite (CPU – GPU cache coherency) and the vStream interface. Other additions include a pixel compression fabric that allows GC7000 to create a streamlined pixel processing pipeline across the ISP, CPU, DSP, memory, and display processor.

GC7000 Series GPU cores come packaged with a single driver software stack that supports board support packages (BSP) running Android KitKat, Chrome OS, Linux, QNX, Tizen and Windows operating systems. They will also support Unreal Engine 4, Unity 4 and the upcoming Unity 5 SDKs

Vivante_GC7000_FamilyThere are currently 6 GPUS available from the GC7000 series with GC7000 UltraLite, GC7000 Lite, GC7000, GC7200, GC7400, and GC7600 with 8 to 256 Vega Shader Cores clocked up to 1GHz, and all supporting OpenGL ES 3.1, OpenGL 2.x desktop, and OpenCL 1.2. Performance will range from 32 to 1024 GFLOPS with medium precision operation, 16 to 512 GFLOPS for higher precision operations, and GC7000 GPUs will be able to deliver up to 25.6 GTextel/s and up to 16 Gvertex/s.

AndroidPC.es also reports GC7000 GPU performance, I’d assume GC7600 performance, should be 40% higher than Nvidia Tegra K1 “Kepler” GPU and 122% higher than Imagination Technologies PowerVR GPU GX6650 “Rogue 2.0″.

Rockchip RK3288 based Android and Chromium OS Tablets and TV Boxes (Video)

April 14th, 2014 2 comments

After the first RK3288 Android TV boxes started to be promoted on Alibaba, and the first RK3288 board was shown, Rockchip is currently showing their quad core Cortex A17 processor in reference designs, tablets, and TV boxes running Android or Chromium OS at the Hong Kong Electronics Fair.

Charbax interviewed the company, and the first demo was a development board connected to an LCD display running Chromium OS, which is said to handle 30 tabs without issues.

Rockchip RK3288 is now advertised as being a quad core Cortex A17 with a Mali-T764 GPU, but when Rockchip representative was asked, he strangely denied to comment on whether it was a Cortex A12 or A17, as both are very similar. He also said the GPU was a Mali-T760MP4… If this seems all confusing that’s because it is… Some interesting things are H.265/HEVC support for 4K2K videos, and HDMI 2.0 for 4K @ 60 fps video output.

Moving on, some TV boxes and boards, such as the reference designs pictured above, were quickly shown, followed by several Android tablets that can boot in about 8 seconds.

Finally, we’ve been told the products should be available in the next few weeks. Based on several comments from people involved in development of such devices, I’d expect the first RK3288 devices to be available early summer (end of June, beginning of July), which tablets possibly becoming available a little earlier.

AMLogic to Unveil M805 & S805 Quad Core Cortex A5 SoCs with Mali-450 GPU

March 4th, 2014 10 comments

As we are still waiting for retail availability of Android TV boxes and mini PCs based on AMLogic S802 quad core processor, rumors have started to surface about another quad core processor by the company called S805 to be used in media players, and probably it’s equivalent M805 for tablets. M803 and M805 were already part of AMLogic roadmap and were said to feature quad core CPU and GPU. It turns out M805 and S805 will feature four ARM Cortex A5 cores @ 1.5 GHz combined with a quad core ARM Mali-450 GPU (Mali-450MP2 ?).

AMLogic_S805That means S805 will be cost down version of S802 with four cortex A5 cores instead of four Cortex A9r4 cores, and Mali-450MP2 instead of Mali-450MP6. The new processor will also support hardware decoded of H.265 @ 1080p, and embed a Gigabit Ethernet controller. If the features listed in the roadmap are still correct, we can also expect the following:

  • Dual channel DDR3/LPDDR3 up to 2GB
  • 64-bit SDRAM bandwidth
  • OS – Android 4.4 Kit Kat
  • BGA package, 28nm HPM.

That probably means no 4K support like in M802/S802. There should also be a M803 tablet version pin-to-pin compatible with M801/M802, and possibly the equivalent S803 for media players.

There’s currently a battle between H.265 (HEVC) and royalty-free VP9 codecs, and some online service may choose one over the other, although I believe they’ll most probably support both as is the case with VP8 and H.264 we all use today. So ideally an SoC should support both, and it will become more and more important to getting hardware with proper H.265 or/and VP9 hardware decoding to get a much better user experience for online video streaming: either not seeing that buffering spinning wheel so often, or/and moving to an higher resolution.

I don’t really see Gigabit Ethernet for a 1080p media player as a big advantage, since I don’t know any 1080p videos that will saturate the 100 Mbps bandwidth. For media centers and 4K videos that’s another story however, and Gigabit Ethernet will become a must.

BroadLink SP2 Wi-Fi Smart Socket for iOS and Android Adds Support for Energy Monitoring, Motion Sensing

March 4th, 2014 1 comment

Broadlink SP1, a low cost Wi-Fi smart socket released last year,  allows you to control your electric appliance with your mobile device running iOS or Android. You could turn it on or off, set timers, and so on. An updated model is now available, Broadlink SP2, that adds energy monitoring to the features found in the previous model, to track your historic and live power consumption on your smartphone or tablet, as well as a motion sensor to automatically turn off the lights, for instance, if you are away (Auto Home / Auto Away feature).

Broadlink SP2 and Energy Monitoring

Broadlink SP2 and Energy Monitoring

The hardware specifications are very similar to SP1 except it’s using a case made of polycarbonate plastic instead of ABS, and the device is a bit bigger:

  • Material – PC
  • Wi-Fi – 802.11 b/g/n
  • Power Plug – Three flat-pin plug (Australia type)
  • Voltage – 100~265V @ 50-60 Hz
  • Output Current – 10A
  • Output Power – 2300W max.
  • Dimensions – 12.3 cm x 7 cm x 6.5 cm
  • Durability – > 50,000 On/Off
  • Temperature Range – -10 C to 60 C

The smart socket comes with a user’s manual in English. Just like with SP1, you’ll need a plug adapter or a universal power strip to use the plug, if you don’t live in Australia, China, Argentina, New Zealand, and the few other countries using this type of plug.

The  “Broadlink” app is apparently the same as for SP1 for iOS 5+ and Android 2.2+ and support English as well as simplified and traditional Chinese. The company SP2 page is not very clear, and there are also other iOS and Android apps, but they must be for other products.

You can purchase Broadlink SP2 on DealExtreme for $45.24, but it should eventually be closer to $36, as it’s available for 179 CNY (About $29) on Taobao excluding shipping. For reference, Broadlink SP1 sells for $35 on dx.com.
