PowerVR graphics give the quad-core Allwinner A31s a competitive edge [With Imagination Blog, March 29, 2013]

Get the most out of your battery and avoid heat issues with PowerVR GPUs

Power consumption is critical for mobile devices, especially for smartphones, smaller tablets and phablets. These devices cannot afford to fit a large battery as their bigger counterparts do, but must still provide high performance computing within this limited power envelope.

As graphics processor units (GPUs) increasingly become the driving force behind SoC processing, scaling the number of graphics IP cores becomes a careful balancing act between performance, power and area requirements.

By choosing a PowerVR SGX544MP2 from Imagination for its A31 and A31s platforms, Allwinner have seen more than 50% increases in graphics and compute performance compared to competing solutions with twice as many cores, running at double the frequency, while keeping power consumption significantly lower. This is an extremely important point for computing platforms.


Because competing solutions are inherently inefficient (essentially brute force designs), they must rely on overclocking to extreme frequencies to provide somewhat decent performance. This leads to dangerous levels of heat (think 72 to 100+ degrees Celsius) which is unacceptable in practical usage. Device temperature should not be massively above body temperature… and definitely not near skin burning temperature.

What about competitive benchmarks?

We’ve seen competitors go to extreme lengths to compete with PowerVR GPUs and claim superior performance by ramping up clock speeds just to run benchmarks. Not only does this give a highly distorted view of what real users will experience, it also gives an unrealistic impression of what the chip is actually capable of.

The trick here is simple: make sure the benchmark runs for the time a typical user will be using the tablet – e.g. 10 or 15 minutes – and see what happens to the temperature of the product and the speed of the benchmark. We’ve seen cases where the temperature rises so high that the tablet quickly becomes impossible to hold, while the thermal management on the chip cuts in (if it was not earlier disabled to mislead even more), plummeting performance to a fraction of their claimed benchmark speeds.

imageHeat measurements from Korean website
[Nexus 10 with Mali T604 an iPad 4 with SGX554MP4]

End users don’t appreciate a hot tablet or wildly fluctuating performance as thermal management cuts in or out. This process of constantly having to adjust a GPU’s working frequency is known as thermal panic linked throttling and it leads to significant fluctuations in the overall experience and chipset performance as the system toggles for example from 600MHz to 300Mhz or even lower to cool the silicon down.

PowerVR is the lowest power GPU in its class, ensuring users get the best possible experience for hours of enjoyment. By using PowerVR GPUs, Imagination’s silicon partners like Allwinner do not run into this problem. Low power technologies unique to the PowerVR architecture such as TBDR (tile-based deferred rendering), PVRTC and PVRTC2 texture compression support, and a separate hardware 2D core all contribute to sustained performance and decreased power consumption.

This in turn improves system-wide, real world performance and reduces memory bandwidth requirements.

PowerVR Series5XT is the graphics engine of choice for high-resolution screens

PowerVR GPUs have been and are at the forefront of high resolution displays, driving complex user interfaces and ultra-realistic games on Retina resolutions (and beyond) for smartphones, tablets, smart TVs and other consumer devices. This trend is likely to continue this year, as we expect newer PowerVR-based smartphones, phablets and tablets to launch with high resolution screens.

When it comes to devices with high-resolution screens, PowerVR Series5XT-based designs like the Allwinner A31s and A31 are leading the market. For example, the Allwinner A31s can drive resolutions up to 1280×800 pixels, decode video up to 2160p, and encode video up to 1080p – perfect for mainstream, high volume phablets that need the added graphics and compute power to compete against more expensive solutions in the market. Allwinner A31s significantly reduces BOM costs by integrating functions like audio, ISP (image signal processor), and voice communication interfaces directly onto the chip.

[Imgtec YouTube channel, March 20, 2013] VeniceScene showcases the high-end OpenGL ES 2.0 graphics capabilities of the PowerVR SGX series by beautifully rendering part of a picturesque canal network similar to those found in Venice itself. Demonstrated here is a wide range of graphics techniques, including vertex displacement, bump-mapping, shadow-mapping, reflections and refractions. These features, coupled with the large amount of geometry in the scene really demonstrate the ability of the PowerVR SGX series.

PowerVR Series5XT GPU cores provide high precision floating point support leading to less rendering artefacts and improved compatibility with a minimal impact on performance.

Near OpenGL ES 3.0 functionality and GPU compute on the same PowerVR GPU

PowerVR Series5XT GPUs are fully-featured, future proof designs, offering much more than a standard API implementation. For example, the PowerVR SGX544MP2 inside the Allwinner A31s and A31 SoCs supports a wide range of graphics APIs, including OpenGL ES 2.0, desktop OpenGL 2.1 (including X11 integration with DRI2, EXA and DRM support), and DirectX 9_3.

More importantly, PowerVR Series5XT GPUs deliver the largest number of OpenGL ES 2.0 extensions available in the industry, bringing OpenGL ES 3.0 functionality on today’s platforms. This gives developers a path for migration between the two versions of the Khronos standard, allowing them to design console quality titles optimized for mobile platforms.

As opposed to other GPU vendors who either are not capable to support (or completely lack the feature set) for OpenCL or Renderscript/Fiterscript APIs, Imagination delivers GPU compute across all PowerVR cores, including Series5, Series5XT and Series6. Our SGX platforms offer up to IEEE 32-bit floating point accuracy for GPU compute and advanced context switching and multi concurrent API support.

This enables PowerVR-based platforms like Allwinner A31s and A31 to offer uncompromised compute and graphics performance across a range of devices.

[Imgtec YouTube channel, March 20, 2013] The Flags demo shows a set of pirate flags blowing realistically in the wind, using real-time cloth simulation powered by OpenCL running on a PowerVR GPU.

The PowerVR SGX544MP core is the most efficient GPU core shipping today in high volume, offering better real device performance and compatibility. Its feature set far exceeds other competing solutions whose obsolete capabilities limit their ability to provide the flexibility and efficiency characteristics required of any mobile and embedded GPU.

Thanks to Imagination’s long and proven track record in developing powerful graphics IP cores and software drivers, PowerVR SGX544 can enable our customers to support popular APIs such as OpenGL ES 2.0, DirectX9_3, desktop OpenGL 2.1 (including X11 integration with DRI2, EXA and DRM support), and OpenCL 1.1 Embedded Profile.

Not only that, but we have recently pushed the boundary for all existing PowerVR Series5XT GPUs with a new series of API extensions which include OpenGL ES 3.0 features like MRTs, occlusion queries, seamless cube maps, sampler access from vertex shaders, floating point textures, GLSL full-precision floating point, R and RG textures, min/max blends, and multisample render buffers. We expect to see developers taking full advantage of all these added features soon, as they provide a valuable differentiator for our semiconductor licensees and OEM partners.

PowerVR SGX544 supports the widest range of texture compression standards, including PVRTC2

Developers targeting current generation platforms will be able to take advantage of PowerVR SGX544’s advanced texture support. Alongside widely adopted texture compression standards like ETC, ETC2, PVRTC and DXTn, all Series5XT and Series6 GPUs supportImagination’s PVRTC2 format. This recently updated texture compression standard adds a wide range of new features including:

  • improved image quality, especially for textures with high contrast, large areas of significant colour discontinuity, or boundaries of non-tiling textures
  • better support for pre-multiplied textures
  • support for arbitrary sized NPOT (Non Power Of Two) textures
  • sub-texturing

PowerVR SGX544 delivers a rapid path to GPU compute through OpenCL, Renderscript and Filterscript

The PowerVR GPU family continues to lead the market in technological capability, roadmap strength and ecosystem. It remains by far the most adopted and shipped technology of its kind.  PowerVR Series5XT has been optimized for graphics and compute efficiency, obtaining better real device performance and compatibility. It is a modern GPU family, whose feature set clearly exceed the obsolete capabilities of other competing cores released in the last four years.

The Series5XT family’s ability to fully support popular graphics and compute standards such as OpenGL ES 2.0, DirectX9_3 and OpenCL 1.1, with new standards added continuously (recent additions include Renderscript and Filterscript), shows the capabilities and extensive feature set of the PowerVR architecture.

Different hardware configurations with PowerVR SGX544 (i.e. Allwinner A31, Intel ‘Clover Trail’, MediaTek MT6589, Samsung Exynos 5410 Octa, etc.) are already starting to ship in mass volume in certain markets, with tablets and smartphones including the Amazon Kindle Fire HD 8.9”, Onda V972, Ramos W33, Ainol Novo 9 Spark, and Samsung Galaxy Premier.

Upcoming flagship devices are soon to follow, making the PowerVR SGX544MP, alongside other existing Series5XTMP cores, the most popular GPU in the mobile and embedded market today.

We expect to see even better levels of performance from PowerVR Series6-based designs, which are starting to ship now and will reach mass-market volume this year. As smartphones and tablets overtake traditional consoles and PC shipments to become the highest volume segment in the computing market, Imagination is driving mobile and embedded graphics performance to reach across the full range of smart consumer devices, from mass market to high end in an era of ubiquitous mobile multimedia.

Tech Focus: IMG on PowerVR mobile graphics [GamesIndustry, April 13, 2011]

IMG talk graphics tech featured in iPad 2 and Sony NGP

Weeks on from the iPad 2 launch, the full graphical power of the new tablet is finally coming into focus – and it’s frankly monstrous, a massive statement of intent from Apple on its plans for the games market.

Apple’s new A5 processor features a dual core PowerVR SGX 543 – the same graphics tech that’s set to be featured in the forthcoming Sony NGP, the difference being that the new PlayStation portable will double the core count, bringing an unprecedented amount of graphical power to the mobile space.

UK-based Imagination Technologies is the engineering force behind the PowerVR graphics tech: in this interview, director of PR David Harold and business development manager Kristof Beets talk frankly about its current range of mobile processors and their capabilities, the importance of its support for DirectX and Open GL standards and discusses some of the custom features found in their GPUs. They also go into depth on the scalability of their hardware and look forward to the emergence of the ARM-based version of Windows.

Finally, if you thought the performance increase between the iPad and iPad 2 GPUs was impressive, the final question we put to Imagination should help put some perspective on that…

Q: A lot of people have tried to bring a TBDR solution to market, but only IMG has achieved it. Why do you think the mainstream GPU manufacturers have stuck to their traditional approaches?

IMG: Partly because although the idea sounds simple it’s actually very hard to do it in practice – especially in such a way that looks like any other renderer to developers. Partly because we have a lot of the fundamental patents.

The total Series5 and Series5XT portfolio enables the industry’s broadest range of performance/area options, from the smallest single pipe SGX520 core up to the 64-pipe SGX543 MP16. All popular APIs and OS are supported by all SGX cores, including OpenGL ES 2.0/1.1, OpenVG 1.1, OpenGL 2.0/3.0 and DirectX 9/10.1 on Symbian, Linux, Android, WinCE/Windows Mobile and Windows 7/Vista/XP.

Q: Now seems to be the time where key IMG partners are transitioning across from the SGX535 onto the SGX543 multi-core products – aside from the multi-core angle, what are the key enhancements you’ve made to the basic architecture itself?

IMG: Our Series5XT architecture (SGX543/544/554) is a significant mid-life update to the Series5 architecture (SGX520/530/531/535/540) which was driven based on market and customer feedback. Key in this feedback was increased interest in compute performance both for GP-GPU via OpenCL but also for higher-quality pixels via more complex shaders as a result we doubled the floating point performance per pipeline in the newer cores while maintaining efficiency via co-issue (dual instruction) capabilities.

Additionally there was an increased interest in compositing User Interfaces and as a result we added dedicated hardware for YUV formats to enable optimal integration with video and camera image streaming. Most of the other changes are much lower level and focused on improving the efficiency of the design including both improved performance and further reduced bandwidth usage – a specific area of focus has been anti-aliasing and polygon throughput.

Q: Is the architecture flexible enough to allow for the GPU cores to carry out non-graphics based tasks? What sort of applications can you see here?

IMG: Absolutely. SGX already has OpenCL conformance and all SGX parts are OpenCL capable. There’s all kinds of things that you can use that for from game-world physics to image processing and enhancement

Q: Stereoscopic 3D is swiftly being embraced by many different types of media, with games taking the spearhead. Does PowerVR architecture offer any specific advantages that makes 3D easier to work with?

IMG: The additional workload required for S3D places significant additional demands on the graphics processor – and PowerVR SGX is more than up to the task. PowerVR SGX graphics acceleration cores are ideally suited to S3D graphics, either using single or multi-processor cores for resolutions up to full 1080p HD, and are capable of supporting all commonly used S3D formats such as frame sequential, side-by-side, top-bottom and interlaced.

Using SGX it is possible to quickly upgrade existing 3D content to deliver full S3D, bringing new realism to 3D games and navigation, and exciting new possibilities for user interfaces in a wide range of applications. The PowerVR SGX tile-based deferred rendering architecture is ideally suited to deal with the increased demands of S3D – which include twice the geometry processing workload and commensurate increases in fill/texturing workload. The scalable nature of the SGX architecture and its ability to efficiently support multiple contexts ensure that the best possible S3D user experience can be achieved using SGX powered devices while maintaining SGX’s unique low power, high performance credentials.

Q: Out of interest, Sony says that it has a PowerVR SGX543 MP4+ inside Sony NGP… what does the plus stand for?

IMG: That’s to indicate the work Sony has done to implement the graphics. What they licensed is a SGX543 MP4.

Q: You have other multi-core projects in the pipeline for the series five hardware. What advantages do they have over the SGX543?

IMG: In addition to SGX543 we have also announced SGX544 which offers the same performance characteristics but enables fully compliant DX9 Feature Level 9_3 capabilities so basically an extra bump in feature set to meet Microsoft requirements. Also available is the SGX554 which is our first 8 pipeline part (SGX543/544 have 4 processing pipelines) which offers improved compute density for customers focused on GP-GPU and shader processing since a single SGX554 would offer the same compute capability as an SGX543 MP2 but not the same geometry or pixel throughput.

This means that SGX554 offers more GFLOPS per mm2 since the design avoid overscaling the geometry and pixel capabilities of the design versus customer requirements – basically we do not believe in “one size fits all” solutions and we thus offer our customers various options.

Q: Finally, we see Apple talking about a 9x performance increase from iPad 1 to iPad 2 and benchmarking of the devices sees at least a 4x “real world” boost in GPU performance. With SGX535 as the baseline, what are your performance targets for your hardware going forward. I’m sure I read somewhere you were looking at a 100x increase within five years

IMG: Yes we are.

Imagination Technologies’ to deliver production-ready IP for POWERVR SGX543MP multi-processor graphics [Imagination Technologies press release, Nov 24, 2009]

Multi-processing graphics technology delivers true scalability to ‘super-high’ performance points

Tokyo, Japan: Imagination Technologies, the leading multimedia chip technologies company, will begin shipping fully verified production quality IP for its POWERVR SGX543MP multiprocessor graphics cores to partners before the end of December 2009. Multiple lead partners have already been working with beta versions of the core for several months and several SoCs for a range of markets incorporating SGX MP cores are already in advanced design.

Imagination reports that three of its partners now have licences for SGX MP technology, which continues to extend Imagination’s leadership of the embedded graphics acceleration market with multi-processor, shader-based solutions which address the rapidly growing demands for high performance graphics in a wide range of consumer electronics segments.

The technology can be delivered to customers in SGXMP2 (two-core) to SGXMP16 (16-core) variants. Graphics IP cores available from Imagination now range from SGX520, the world’s smallest OpenGL™ ES 2.0 mobile core, to SGX543MP solutions for high-performance console and computing devices. POWERVR SGX543MP delivers performance comparable to many desktops, laptops and games consoles.

Further details of the innovative technology behind POWERVR SGX543MP are being revealed to press and customers at the Embedded Technology Show in Yokohama, Japan from 18-20th November 2009.

Tony King-Smith, VP marketing Imagination Technologies says: “With the ability to combine up to sixteen SGX543MP GP-GPU cores on a single SoC, we are now able to deliver capabilities to our licensing  partners previously only thought the domain of the discrete GPU chipset vendors, while maintaining our unrivalled power, area and bandwidth efficiency.”

The POWERVR SGX543MP family enables POWERVR SGX543 four-pipe programmable GP-GPU cores, to be integrated in a high performance, multi-processor graphics solution without performance or silicon area compromises. SGX543MP enables highly linear scaling of all aspects of GPU performance, specifically vertex shading, pixel shading, primitive setup and overall GP-GPU* functionality, whilst maintaining full software compatibility and with virtually no overhead in bandwidth usage.

At 200MHz core frequency an SGX543MP4 (four cores) will deliver 133 million polygons per second*** and fill rates in excess of 4Gpixels/sec**. Higher frequencies or a larger number of cores each deliver more performance. At 400MHz core frequency an SGX543MP8 (eight cores) will deliver 532 million polygons per second*** and fill rates in excess of 16Gpixels/sec**.

The highly efficient POWERVR SGX543MP family delivers near linear progression in vertex and pixel processing performance, unlike competitive solutions which scale only pixel performance. An SGX543MP2 delivers effectively twice the performance of a single SGX543 without compromise. And for a given workload the same bandwidth is required no matter how many cores are deployed – SGX543MP delivers faster performance by dividing the work on-demand, dynamically load balanced in parallel between cores.

The USSE2 (Universal Scalable Shader Engine v2), a key component of Series5XT architecture at the heart of SGX543MP is a scalable multi-threaded multimedia processing engine offering up to 2x the floating point throughput of earlier Series5 SGX IP cores. An extended instruction set with comprehensive vector operations and co-issue capabilities enables advanced geometry and pixel processing as well as GP-GPU tasks. These tasks are broken down into processing packets which are then scheduled across a number of multi-threaded execution units in the USSE2. This enables optimal hardware load balancing, maximum latency tolerance and efficient gate use, all accessed through a single software programming model and compiler.

POWERVR SGX543MP features:

  • the highest performance per mW of any embedded graphics core
  • highly linear scaling (over 95% efficiency) of performance in both geometry (vertex processing) and rasterisation (pixel/fragment processing)
  • dynamic load balancing and on-demand task allocation at the pipeline level
  • no fixed allocation of given pixels to specific cores, enabling maximum processing power to be allocated to the areas of highest on-screen action
  • scalable GP-GPU compute power, which can be fully utilised through all Khronos APIs including OpenGL ES 2.0/1.1, OpenVG™ 1.x and OpenCL™
  • use any number of cores, even or odd
  • no additional work for software developers; using one driver stack for all SGX cores means applications see a common SGX architecture via the standard APIs regardless of number of cores used
  • no additional CPU load when using multiple cores or loss of performance
  • individual cores can be disabled based on workload for optimal power saving
