Qualcomm's new Adreno 530 GPU won't be something you'll find in any phone until next year, but nonetheless the newer, better, faster GPU powering the upcoming Snapdragon 820 chipset was detailed (well, lightly detailed) at SIGGRAPH 2015 this week. Qualcomm also confirmed that Snapdragon 820 devices will be available starting in the first half of 2016 - all but ruling out the chip in rumored Nexus devices launching this fall (unless, of course, they're not launching until next year).
While the rest of Snapdragon 820 is still largely under wraps, the new Adreno 530 was described to us in a short presentation, with the major figures to take away being a 40% increase in speed over the Adreno 430, along with a 40% decrease in power consumption under the same workload. The latter is obviously of great interest for battery life during GPU intensive activities like gaming or video and image editing. Of course, just how these gains will play out in real world battery life and performance remains to be seen. Qualcomm claims some of the gains are from an all-new GPU power manager, but a good chunk of that is also likely derived from the smaller FinFET process being used across the 820 SoC.
Qualcomm claims the newest Adreno is a significant overhaul compared to the 400 series chips, with improvements across the board on the graphics and image processing stacks, as well in how the GPU is able to work with the CPU in more and more meaningful ways. The abilities of the new Spectra image signal processor (only in the Adreno 530) and related software advances were a key point during Qualcomm's presentation, with the company claiming a number of improvements to image processing across multiple fronts.
Enhanced noise reduction ready for the newest generation of mobile image sensors (which the 820 can support at up to 25MP or dual 13MP sensors simultaneously), "zig zag" video HDR capture support, more intelligent correction of lens and sensor aberrations, and increased autofocus performance are all potential benefits. Should phone OEMs choose to take advantage of them, of course.
The Adreno 530 has the kind of standards support you'd expect of a high-end GPU in 2016 - Miracast 4K30, HDMI 2.0 at 4K60, the new Vulkan graphics API slated for support in Android, OpenGL ES 3.1, and Open CL 2.0.
Other details were light, though Qualcomm has never been particularly forthcoming about its GPU hardware technology and designs. You can see more information in the slides below, as well as in the press release. As to the titular Adreno 510? All we were told is that it won't feature the fancy new Spectra ISP, and that it will be in the upcoming Snapdragon 620 and 618 chips.
Qualcomm Introduces Next-Generation GPU Architecture and Image Signal Processor for the Ultimate Graphics and Mobile Camera Experience
- New Custom Adreno 5xx GPU and Spectra ISP Bring the Most Advanced Visual Processing Technology to Snapdragon Processors -
Los Angeles, CA, August 12, 2015 – Qualcomm Incorporated (NASDAQ: QCOM) today announced that its subsidiary, Qualcomm Technologies, Inc. (QTI), has introduced its next-generation visual processing technology with new versions of its graphics processing unit (GPU) and image signal processing (ISP) unit, to deliver significant advancements in performance, power efficiency and user experience to Snapdragon™ processors. The new Adreno™ 5xx GPU architecture delivers increased speed and efficiency over the previous generation and supports stunning high-definition mobile graphics while introducing general-purpose compute co-processing for exceptionally low power consumption. The first two GPUs available on the new architecture, the Adreno 530 and Adreno 510, will be available integrated within the forthcoming Snapdragon 820 and Snapdragon 620/618 processors. In addition, Snapdragon 820 will also debut the new 14-bit Qualcomm SpectraTM image signal processing (ISP) unit, designed to support superior DSLR-quality photography and enhanced computer vision. Devices based on Snapdragon 820 are expected to be available in 1H 2016.
“We’re significantly enhancing the visual processing capabilities of Snapdragon to support next-generation user experiences related to computational photography, computer vision, virtual reality and photo-realistic graphics on mobile devices, all while maximizing battery life,” said Tim Leland, vice president, product management, Qualcomm Technologies, Inc. “Spectra ISP, together with our Adreno 5xx-class GPU, brings an entirely new level of imaging to smartphones, and is designed to allow Snapdragon-powered devices to capture ultra-clear, vivid photos and videos regardless of motion and lighting conditions and display them with the color accuracy that nature intended. In addition, as emerging growth segments such as automotive demand more immersive visual experiences, Snapdragon 820 will enable the next generation of infotainment, computer vision and advanced processing for instrument clusters.”
Designed for scalability, the Adreno 5xx architecture is the foundation of Qualcomm Technologies’ next-generation custom GPUs and is the successor to the Adreno 4xx family. Newly integrated within the Snapdragon 820, the Adreno 530 is the highest-performance GPU ever designed by Qualcomm Technologies, providing superior experiences with:
- Up to 40 percent lower power consumption and 40 percent faster performance for both graphics and GPGPU compute when compared to the Adreno 430
- Leading-edge capabilities in graphics and compute APIs including OpenGL ES 3.1+AEP (Adreno Extension Pack), Renderscript, as well as the new OpenCL 2.0 and Vulkan standards. Vulkan minimizes driver overhead and enables multi-threaded performance on mobile and embedded platforms.
- Support for 64-bit virtual addressing, allowing for shared virtual memory (SVM) and efficient co-processing with 64 bit CPUs
- Improved fine-grain power management, new rendering, compositing and compression techniques to enable higher performance at lower power consumption and reduced DRAM bandwidth
- Up to 4K HEVC video support at 60fps over HDMI 2.0 to Rec. 2020 ultra-high definition (UHD) displays and TVs
- Improved EcoPix™ and TruPalette™ support for longer battery life and superior pixel quality
- Software compatibility between Adreno 530 and Adreno 510
Introduced with the Snapdragon 820, Spectra ISP is Qualcomm Technologies’ most advanced dual-imaging signal processing unit to-date, integrated and designed to provide best-in-class camera image quality and end-user benefits, including:
- Superior image quality, with more natural skin tones via advanced, 14-bit dual ISPs supporting up to 3 simultaneous cameras (e.g. one facing the user, and two rear facing), and up to 25 megapixels at 30 frames per-second with zero shutter lag
- Improved photos with Qualcomm Spectra ISP’s flexible hybrid autofocus framework and multi-sensor fusion algorithms supporting next generation computational photography
- Improved power efficiency when compared to previous generations, better noise immunity and higher throughput via advanced compression techniques and use of the latest MIPI serial C-PHY interface
- Next generation Computer Vision and other use cases via direct-to-DSP raw bayer data streaming and pre-processing capabilities
