No need to develop and alternative when you can trick MKL into not crippling AMD: https://www.pugetsystems.com/labs/hpc/How-To-Use-MKL-with-AM...

Edit: the link I posted follows Agner's advice from the bottom of OPs link. However I think the extra information that it adds is that Zen2 Threadrippers outpaced then-current Intel's top contender. Once Zen3 and Intel's 11th Gen become available, repeating this benchmarks would be very valuable.

Thank you! I wasn't aware of this. But this is only a replacement for libm (i.e. basic trig, exp function), not the matrix-orientated BLAS, LAPACK and SCALAPACK routines that scientific codes spend >90% of their time.
