I am purchasing two workstations for CFD (CFX) as well as FEA (ANSYS Mechanical)


OS will be windows 10.



I was leaning towards EPYC ROME 7302, but have seen a fair amount of literature stating INTEL should be better for ANSYS mechanical.

The mechanical benchmarks in this presentation are only for EPYC naples. And show lower performance than Intel. But so do the CFD benchmarks between INTEL and EPYC Naples. While the CFD benchmarks for INTEL vs ROME, show ROME on top, which has been proven around here as well.

The ANSYS hardware recommendations say Intel CPUs should be used because of AVX512 support.

Also, most of the time I will not be using all cores on the node, I will probably only be solving on 8 cores (16 max). Anyone have any mechanical benchmarks for XEON GOLD vs EPYC ROME on a core to core basis? Any advice for picking between the two?


Thanks in advance,
Erik
