Best CPU settings to match the Ryzen 3700x/3800x/3900x

Hello good people of VMware.

I have a VM separating my personal (host) from my work (VM), I want to insure that my VM is getting the best performance possible.

I'm planing on buying one of the CPUs listed in the title, and I want to know what are the best VM settings for those processors? Knowing that:

  • Both the 3700x/3800x are 8 cores 16 thread processors.
  • The 3900x is a 12 cores 24 thread processor.

I hear that the general recommendation for the CPU settings for Workstation Pro is to always have a 1 CPU and 4 cores per VM, does that still stand with the above CPUs? or should I use something like:

  • For the 3700x/3800x: 2 CPUs / 8 cores.
  • For the 3800x: 4 CPUs / 16 cores.

If the above cannot be answered without more information, perhaps then a better question would be as follow: how does CPU count and cores in Workstation Pro translate to the real CPU/cores in host?
