I could not find an exact answer. What I came away thinking was a vCPU is equal to a thread. From what you are saying it sounds like a vCPU is a shared resource, so there may be more vCPUs than actual threads? Is there a way I can determine the number of vCPUs a CPU will provide? --- > > On Thu, Jul 20, 2023, at 10:26 AM, Keith Smith via PLUG-discuss wrote: > >> Hi, >> >> I was surfing the Inter Web when I happened upon a Xeon server CPU. >> It >> >> is marked at $32.49 at Newegg.
