HFSS simulation slow for Ryzen CPUs
I just bought a new computer with AMD Ryzen 3950x which has 16 physical cores. All benchmarks done on this computer shows satisfying results but when I try to work with Ansys Electronics Desktop(HFSS) it consumes even longer time than my previous PC with Intel Core i5-9500. I've already set the HPC options to fully utilize 16 physical cores and the frequency of processor is manually set to 4.2GHz during the simulation. The Solution Data page shows that simulation done on 3950x platform cost about 3x CPU Time as my Intel PC, e.g., solution for a model may cost about 20m on AMD R9-3950x while 7m on Intel i5-9500. Although 3950x has more physical cores and same working frequency, the CPU Time cost make it even worse than i5-9500. I've tried several releases of Ansys software including the up-to-date 2020R1 sutie, none of them can reduce the CPU time cost.
Is there anyone working with AMD Ryzen computers? Can I make better use of my processor by tuning some settings? Thanks for your advice.
