As far as I know, the only main reason to have a high clock speed CPU in a server is for game servers, at least for me. (And also for a router, but that doesont really apply here).
My basic question is this:
- Xeon 2690 v2
- 10 cores, 3Ghz Base, 3.6 Boost
- 2667 v2
- 8 Cores, 3.3Ghz Base, 4 Boost
- 2643 v2
- 6 Cores, 3.5Ghz Base, 3.8 Boost
Which should I get? All 3 have a 130W tdp.
For background this is for a new server I want to build alongside two I already have, which are in a proxmox cluster. This new one will join them.
One of the servers has Dual 2670 v2s and the other has a single 1230 v2.
A 2670 only has a 2.5 base and 2.2 boost, which is why im wondering if having another server with less cores but a higher clock speed would be beneficial for certain tasks.
Currently I run things like plex, nextcloud, homeassisstant etc, and game servers.
It depends on your usage. If you are going general purpose I would aim from the middle ground.
If your running loads of services that scale horizontally go for more cores. If you have services that scale vertically go for speed
