No, I don't. The 32-core AWS systems must be Epyc, so I'll try benchmarking there.
When OpenBLAS identifies the arch, it is competitive with MKL in single threaded performance, at least for matrices with a couple hundred rows and columns or more.
But MKL truly shines with multiple threads, so scaling on a 32 core system would be interesting to look at.
