Mike Zhang, CEO, Allwinner Technology, said:”For the past year, our worldwide customer base has grown significantly,enabling us to deliver high quality products at extremely affordable prices.  OEMs from all tiers – top,middle, and low – recognize our leading market position and continue to chooseour processors to deliver outstanding value to their customers.”

“Fundamentally, the UltraOcta A80 and its platforms give OEMs the highest performance, most power-efficient and cost-effective solution for a range of devices, including tablets, portable game consoles, STBs, media players and many others.  We’re excited to see the first UltraOcta devices hit the market soon.”

“We are pleased to see Allwinner delivering a leading solution for 2014 mobile devices that demand premium performance and energy efficiency enabled by an ARMbig.LITTLE system pairing the Cortex-A15 and Cortex-A7 processors,” said Nandan Nayampally, vice president of marketing, CPU group, ARM. “We look forward to seeing real devices based on the UltraOcta A80 processor coming to market in the next few months to provide users with an outstanding user experience enabled by big.LITTLE technology.”

Key Features:

Ultra low power, high performance 28nm UltraOcta SoC with heterogeneous eight-core CPU computing

Ultra performance graphics – PowerVR™ G6230 GPU with two shader clusters and 64 ALU cores

Ultra power-adaptive CoolFlex™ power management system

Next generation video engine – 4K encode/decode, H.265

Triple-screen display support – advanced triple-screen display engine

Proven low power credentials -CoolFlex™

Keeping power consumption to a minimum has been a key focus for Allwinners new UltraOcta A80.  With CoolFlex™, UltraOcta enables max performance for applications while keeping overall power consumption low.  CoolFlex™ uses optimized big.LITTLE technology to dynamically activate energy-efficient or high performance processor cores based on computing workload.  The end result for devices is higher average battery life and faster performance when applications need it. 

The PowerVR G6230 Rogue GPU from Imagination Technologies sits at the heart of the SoC. The G6230 graphics core incorporates PVR3C, a series of power saving technologies designed to keep devices running smoothly while delivering peak performance:

PVRTC and PVRTC2 are currently the most used and lowest power texture compression formats in the market.

PVRIC (lossless image compression) delivers dramatically improved throughput, reduced bandwidth, conserved power and improved     system performance.

PVRGC (lossless geometry compression) reduces overall bandwidth usage and related system costs as the geometry complexity, especially in today’s gaming environments, continues to increase.

Leading edge graphics and GPUcompute performance

Advanced 3D gaming, high-resolution graphical UIs, and web browsing at lightning-fast speeds are a breeze on UltraOcta A80 platforms, thanks to its dual-cluster PowerVR G6230 GPU.  The dual-cluster Rogue is a sophisticated GPU design focused on delivering the most efficient graphics and compute engine and offers a series of key advantages over competing solutions, including:

–         64 FP32 ALU cores

The PowerVR Series6 Rogue cores include Unified Scalable Clusters (or USCs); each cluster contains 16 pipelines and each pipeline has 2 FP32 ALUs. The PowerVR G6230 GPU is a dual-cluster design that has a total of 64 FP32 ALU cores, offering superior processing power and improved precision for better image quality in console-quality games.  Additionally, the PowerVR G6230 GPU includes a number of FP16 cores which provide additional low-power performance for arange of graphics applications, including fast blending for HDR rendering ingames and UIs.

 –         Scalar processing

Scalar processing achieves the highest utilization of ALUs and eases graphics programming. Whereas vector arithmetic units occupy more silicon than a scalar unit and might not be fully used if code is not operating on vectors, scalar ALUs handle algorithms written with scalarops (R), vec2 ops (RG), vec3 (RGB) or a full vec4 (RGBA) with the same efficiency.In addition,scalar instructions decrease the complexity of the instruction set, requiring less chip area for the instruction decoder.

–         Unified architecture

The superior efficiency of Rogue GPUs is derived from its advanced tiling-based deferred architecture combined with aunified shader approach to the programmable elements of the GPU.  The combination of these two characteristics provides phenomenal latency tolerance; along with automatic load balancing,this allows the PowerVR G6230 GPU to process geometry, fragment and computetasks with equal ease.

 –         Leading API support

Application developers can take advantage of the significant parallel processing power in PowerVR G6230 GPU for both graphics and GPU compute tasks.  Thanks to the powerful Rogue architecture on which PowerVR G6230 is based on, the Allwinner A80 processor is able to support all major mobile and desktop APIs,including OpenGL ES Next/3.0/2.0, OpenGL 3.x, DirectX 9_3/10, OpenCL and Renderscript.

Sir Hossein Yassaie, CEO, Imagination Technologies, said, “Our long-standing strategic relationship with Allwinner has resulted in a series of amazing products that offer high performance and low power consumption for highly affordable devices. The graphics and compute capabilities of the newly-announced Allwinner UltraOcta A80 processor are truly impressive. 

“With the UltraOcta processor, Allwinner are leveraging the full benefits of the Rogue GPU architecture to provide thebest combination of features. The choice of a fully-featured PowerVR G6230 GPU enables them to deliver one of the best platforms for Android and other operating systems.”
