The Qualcomm Adreno 512 is a mobile graphics card for mid-range smartphones and tablets (mostly Android based). It is included in the Qualcomm Snapdragon 660 SoCs and based on the Adreno 500 architecture (like the Adreno 520 in the S820, which should be fully compatible in software).
According to Qualcomm up to 30% faster than the previous generation (Adreno 510?).
The GPU supports modern standards like Vulkan 1.0 (according to Wikipedia), OpenGL ES 3.1 + AE (3.2 in other sources), OpenCL 2.0 and DirectX 12 (FL 12.1 according to Wikipedia, 11.1 according to Qualcomm). Furthermore, the GPU supports Universal Bandwidth Compression (UBWC) to save memory bandwidth.
The Imagination Technologies PowerVR GXA6850 is a fast mobile graphics solution (mainly) for tablets, which can be found in ARM SoCs such as the Apple A8X (iPad Air 2). The chip is available since Q3/2014 and of one of the fastest solutions in its class at the time of introduction.
Architecture and Performance
In contrast to previous speculations, the A8X integrates an 8-cluster PowerVR Series 6 (Rogue) GXA6850 consisting of two GX6450 GPUs (2x 4 clusters) instead of a single GX6650 (6 clusters). The name GXA6850 has been created by Anandtech, the design may also be called a GX6450MP2.
Each cluster offers four FP16 and two FP32 ALUs, leading to a compute power of about 230 GFLOPS FP32 at 450 MHz (clock rate estimated). The GXA6850 does not only beat the Qualcomm Adreno 420 (Snapdragon 805), but also the Nvidia Tegra K1 by a small margin. Thus, the GXA6850 is one of the fastest tablet GPUs as of 2014 and can handle even the most demanding mobile games in high resolutions. Among others, the GPU supports OpenGL 3.x/4.x, OpenGL ES 3.0 as well as DirectX 10.
Power Consumption
Thanks to the advanced 20-nanometer process and the relatively low clock rate, the GXA6850 implementation in Apple's A8X offers a very high energy efficiency. On the other hand, the GPU has a comparatively "wide" architecture requirering a lot of transistors and die size (about 38 mm² in 20 nm).
The Qualcomm Adreno 504 is a mobile graphics card for lower mid-range smartphones and tablets (mostly Android based). It is included in the Qualcomm Snapdragon 429 SoCs and based on the Adreno 500 architecture (like the Adreno 520 in the S820, which should be fully compatible in software).
The GPU supports modern standards like Vulkan 1.0 (according to Wikipedia), OpenGL ES 3.1 + AE (3.2 in other sources), OpenCL 2.0 and DirectX 12 (FL 12.1 according to Wikipedia, 11.1 according to Qualcomm). Furthermore, the GPU supports Universal Bandwidth Compression (UBWC) to save memory bandwidth.
According to Qualcomm, the GPU is 50% faster than the previous Adreno 308 in the Snapdragon 425.
In the Snapdragon 429, the Adreno 504 is manufactured in the modern 12nm process and should be very power efficient.
