@MasterOSkillio said in Intel CPUs with P and E cores or other server CPU suggestions:

From what I have seen in various places on the web P and E cores are not really supported yet for XCP-NG? Is it safe to assume that is changing? I believe proxmox, and VMware have moved to support them. If I use the 12600K will I have to turn off one (P or E) and use only the other?

Not sure what you mean by "support" but I'm running as of now the P+E core setup and it works just fine. Stable, performs as expected.
