Hmm. FWIW, on my [Skylake/Cascadelake]-X Intel systems, Intel's compilers performed well, almost always outperforming GCC and Clang. But on Zen, their performance was terrible. So I was happy to see that MKL, unlike the compilers, did not appear to gimp AMD. It's disappointing that MKL doesn't use optimized code paths on the 3700X. I messaged the person who actually ran the benchmarks and owns the laptop, asking them to chime in with more information. I'm just the person who wrote that benchmark suite.
