The iPad Pro would likely use half-precision for some of the GPU workload. If run at 16-bit, that number would double, in theory. An AMD Ryzen 2700U SoC has a Vega GPU which offers 1.66 TFLOPS of FP32 performance, in theory. ![]() Overall, that makes like-for-like PC comparisons difficult. We’ve seen some movement on the PC side to use half-precision GPUs for compute, but for gaming, that’s not currently the case. This is as oppposed to the mobile world, where power is an absolute factor for everything, Vertex shaders are typically 32bpc while Pixel and Compute shaders can often be 16bpc. But for better or worse, when the PC moved to unified shaders, the industry moved to FP32 for all GPU functions. In rough terms, the Xbox One S is roughly 1.4 TFLOPS at its peak. ![]() There’s now seven of the A12 GPU cores, compared to just four on the iPhone, and Apple claims the GPU in the iPad Pro is equivalent to an Xbox One S, although how they came to thise conclusion is difficult to say since we know so little about the underpinnings of the GPU. And with the larger surface area of the iPad compared to the phone, likely a higher frequency as well. ![]() ![]() Apple’s custom GPU in the iPad Pro is the same one found in the iPhone, but with more cores available.
