The fastest GPU IP ever
Shanghai, China; 3rd December 2019 – Imagination Technologies announces the tenth generation of its PowerVR graphics architecture, the IMG A-Series. The fastest GPU IP ever released, IMG A-Series evolves the PowerVR GPU architecture to fulfil the graphics and compute needs of the full spectrum of next-generation devices. Designed to be “The GPU of Everything” IMG A-Series is the ultimate solution for multiple markets, from automotive, AIoT, and computing through to DTV/STB/OTT, mobile and server.
The IMG A-Series’ multi-dimensional approach to performance scalability ranges from 1 pixel per clock (PPC) parts for the entry-level market right up to 2 TFLOP cores for performance devices, and beyond that to multi-core solutions for cloud applications.
Dr. Ron Black, CEO, Imagination Technologies, says: “IMG A-Series is our most important GPU launch since we delivered the first mobile PowerVR GPU 15 years ago and the best GPU IP for mobile ever made. It offers the best performance over sustained time periods and at low power budgets across all markets. It really is the GPU of everything.”
In every dimension IMG A-Series delivers a significant improvement, at the same clock and process, offering 2.5x the performance, 8x faster machine learning processing and 60% lower power than current PowerVR devices shipping.
Compared to other GPU IP solutions available today IMG A-Series delivers higher performance, lower power (compared to competitors at the same clock and process), and lower bandwidth (at the same cache size as competitors) and all at a smaller silicon size. Its architecture also offers strong differentiators such as guaranteed 50% image compression data (lossless in most cases, or visually lossless in exception cases).
Jon Peddie, principle and founder, Jon Peddie Research, says: “The simple fact is that for mobile SoCs the market leader owns its own GPU technology and is increasing market share at rate of 5% year-on-year. In order to stop the losses to their own potential share the other mobile SoC companies need a compelling GPU that will deliver some real competition. Imagination’s A-Series can do that.”
IMG A-Series is already licensed for multiple markets and the first SoC devices are expected in 2020.
The IMG A-Series cores
IMG A-Series, the highest performance mobile GPU IP ever released, is available in four high-performance configurations:
- IMG AXT-64-2048 for flagship performance; 2.0 TFLOPS, 64 Gpixels and 8 TOPS of AI performance
- IMG AXT-48-1536 for premium mobile; 1.5 TFLOPS, 48 Gpixels and 6 TOPS
- IMG AXT-32-1024 for high-performance mobile and automotive; 1 TFLOPs, 32 Gpixels and 4 TOPS
- IMG AXT-16-512 for high-mid-performance mobile and automotive; 0.5 TFLOPS, 16 Gpixels and 2 TOPS
- IMG AXM-8-256 for mid-range mobile; 0.25 TFLOPS, 8 Gpixels and 1 TOPS
For lower cost segments IMG A-Series delivers the best in area, cost and efficiency:
- IMG AXE-2-16 for premium IoT, entry DTV/STB, display and other fillrate driven applications; 2 PPC, 16 GFLOPS and 2 Gpixels
- IMG AXE-1-16 for entry-level mobile and IoT and the fastest Vulkan-capable GPU in its class; 1 PPC, 16 GFLOPS and 1 Gpixels
The Gamers GPU
Most mobile GPUs struggle to deliver consistent gaming experiences due to thermal constraints – they are fast for a short while, then slow to unacceptable levels and then never recover, resulting in a disappointing user experience. IMG A-Series delivers sustained performance for extended game play at consistent frame rates avoiding thermal panic clock throttling, glitches or overheating.
IMG A-Series’ PowerVR architecture has an inherent bandwidth and power advantage because its tile-based deferred rendering technology means it only draws what is visible on screen. This is combined with advanced direct flexible power signalling using Pro-Active DVFS (Dynamic Voltage and Frequency Scaling) and Deadline Scheduling algorithms, which deliver fast power control with ultra-low latency response. If parts of the GPU aren’t fully utilised or needed for processing, they are immediately slowed down or even put to sleep to ensure optimal power efficiency.
The IMG A-Series aims to deliver the best gaming user experience by delivering sustained stable framerates. This requires high GPU power efficiency and this is provided by PowerVR’s smart flexible firmware based low-latency DVFS algorithms with a direct GPIO control path into the system. All of this is combined with a strong focus on delivering visually impeccable pixels via features such as the industry-leading visually lossless PVRIC compression and completely reworked anisotropic sampling and level of detail algorithms.
Jane, vice president, Chukong Technologies, says; “Gaming today requires considerable graphics processing capability. With gaming accounting for over 40% of all smartphone use, having the best GPU is a key differentiator. Imagination is again pushing the boundaries of what is possible with mobile graphics, combining fast and consistent GPU performance with sustained battery life.”
IMG A-Series is supporting by the industry’s leading toolset and SDK, offering new features, such as hardware-based tile heat maps, to help developers optimise their content.
The IMG A-Series features Imagination’s HyperLane technology; individual hardware control lanes, each isolated in memory, enabling different tasks to be submitted to the GPU simultaneously for secure GPU multitasking. With Dynamic Performance Control, the GPU can spread its performance across these multiple tasks, executing them all, while maximising GPU utilisation. Priority HyperLanes deliver a dynamic split; for example, prioritising graphics and delivering all the required performance for that application while an AI task runs alongside using the remaining performance. HyperLane technology can also isolate protected content for rights management. All IMG A-Series GPUs support up to eight HyperLanes.
HyperLane also enables a new feature, AI Synergy. This new option enables SoC designers to take advantage of the incredible levels of compute capability in the IMG A-Series to accelerate their AI workloads. Through AI Synergy the GPU delivers graphics performance, while using its spare resource to enable programmable AI alongside a fixed-function, highly-optimised Imagination neural network accelerator. AI Synergy delivers programmable AI in the lowest silicon area, while a unified software stack enables flexibility and great performance.
