That is a good catch, double speed FP16, so FP32 perf should be half that on the X1. While useful for some things (like neural network inference and I guess some shaders) it's not directly comparable - NVidia style marketing
- banachtarski 10y agoThis was the same deal with how CPUs were (mis)marketed for years. Higher clockspeeds don't mean anything unless the pipelines are identical. A much smarter chip with larger cache sizes, branch prediction, SIMT, ultra-wide registers, better instruction caching, etc might have half the clockspeed of a dumber chip and outperform it by a huge margin. GPUs are no different in that texture caches, vertex buffer sizes, warp sizes, etc all play a big part and you really can't compare flops unless comparing two GPUs of the same product line.
