ADRENO 530 GPU
This is Qualcomm's highest performing GPU, which can reportedly deliver up to 40 percent more performance than the Adreno 430 GPU on the Snapdragon 810. In fact, Qualcomm is also claiming a similar 40-percent reduction in power consumption compared to the previous generation chip, so you should be able to run more demanding games for longer.
The GPU operates between 133MHz and 634MHz, and features small architectural tweaks over the Adreno 430 for further improvements. For instance, it now makes better use of data compression when handling and moving data around in order to lower power consumption. Video processing is also another area where Qualcomm has achieved marked increases in compute performance, up to 2.5x better than the Adreno 400 series GPU.
The Adreno 530 will also support Vulkan 1.0, the recently-released cross-platform, open-source API. Vulkan gives game and application developers explicit control over the GPU's resources and allows them to leverage multi-threaded architectures more effectively, and support for Vulkan thus positions Snapdragon 820-equipped phones to enjoy the improved performance and experience offered by applications that use Vulkan.
