It's interesting how this is still a major issue today, Last month I learned about the Matlab AMD crippling issue. With the workaround AMD performance on a 3960x increased by 30%. "[...] the Intel MKL uses a discriminative CPU Dispatcher that does not use efficient codepath according to SIMD support by the CPU, but based on the result of a vendor string query. If the CPU is from AMD, the MKL does not use SSE3-SSE4 or AVX1/2 extensions but falls back to SSE1 no matter whether the AMD CPU supports more efficient SIMD extensions like AVX2 or not." https://www.extremetech.com/computing/302650-how-to-bypass-matlab-cripple-amd-ryzen-threadripper-cpus https://www.extremetech.com/computing/302650-how-to-bypass-m... https://www.reddit.com/r/Amd/comments/e24jqp/extremetech_how_to_bypass_matlabs_cripple_amd_cpu/ https://www.reddit.com/r/Amd/comments/e24jqp/extremetech_how...
