February 5, 20197 yr I want my next Unraid build to have the ability for 2 gaming VMs with great performance, and I'm trying to decide which CPU to go with. I have a GTX 1070 (me) and a GTX 1060 (kids). Will I be better off with more cores (Threadripper 1920x or 1950x) or more speed with less cores (Intel 9900k)? Would my gaming experience suffer using on 2-3 physical cores (4-6 HT cores) per VM if using the 9900k? (leaving me with 2 cores to run dockers/pfsense?) or use Threadripper and give out 4-5 physical (8-10 HT cores) per VM? does anybody know of a synthetic benchmark for processors where amount of cores can be adjusted so I could figure this out?
February 5, 20197 yr Just run prime 95 on each machine with the heaven benchmark also and run for 24ish hours- that should give you a good thermal benchmark and determine stability. I did it like this- assemble hardware- install windows bare metal- run testing for full load- install unraid and then spin up all machines- test again with all systems maxed.... should give you a good idea. As far as speed- the intel option is your go to- but I find that my 1920x is plenty for 4 gamer VMs- even with most AAA titles. I have dual hyperthreaded cores assigned to each- that is enough for all but the most demanding games. P95 will run on all cores- or allow you to assign how many.
