Lczero Neural Network Chess Benchmarks With OpenCL Radeon vs. NVIDIA

Yesterday I posted a number of Lczero chess engine benchmarks on NVIDIA GPUs using its OpenCL back-end as well as its CUDA+cuDNN back-end, which offered massive performance gains compared to CL on the many tested NVIDIA GPUs. With the CUDA+cuDNN code performing so much better than OpenCL, some wondered whether NVIDIA was intentionally gimping their OpenCL performance. Well, here are results side-by-side now with Radeon GPUs on OpenCL...
