Googling gives the impression that AMD is back in the HPC-game, for example NAMD seems to run very well: https://www.anandtech.com/show/11544/intel-skylake-ep-vs-amd-epyc-7000-cpu-battle-of-the-decade/21 If anyone has some more experience, or has found other benchmarks out there, I would be very happy to hear about it!
