Welcome!
This is true, and it will be for most all scenarios. The very high core count EPYCs are better suited to virtualization workloads where all the cores aren’t competing for the relatively limited memory resources; that being said, a dual socket F series 9374F EPYC system is currently on the top of the benchmark performance charts in the thread linked at the bottom.
Information about FEA performance can still be somewhat of an art more than a science, although there are some trends that emerge, like running on Linux always gives better performance than Windows, and that smaller problems don’t take advantage of larger systems with many cores and channels of memory very well.
no problem, I don’t mind running it on some of the machines I have.
Also don’t count Apple out of the race, their old M1 Ultra is actually beating a Threadripper 7960X in the CFD+Electromagnetic simulation (Threadripper was running on Windows though which is a handicap) in the following benchmark thread:
