AMDGPU-PRO 18.50 vs. ROCm 2.0 OpenCL Performance: When recently publishing the PlaidML deep learning benchmarks and lczero chess neural network OpenCL tests, some Phoronix readers mentioned they were seeing vastly different results with using the PAL OpenCL driver in AMDGPU-PRO (Radeon Software) compared to using the ROCm compute stack. So for seeing how those two separate AMD OpenCL drivers compare, here are some benchmark results with a Vega GPU while testing ROCm 2.0 and AMDGPU-PRO 18.50.
