Hello people,

as the title suggests, I need your help for a moment.
I stand between the two CPUs for my Homelab. Which CPU do you think is better (performance vs efficiency)?

3700x (8 cores)
5600x (6 cores)

I think you should simply grab what you prefer. The difference between those both is the price...

I would probably go with 5800x if the money allows. After that probably personally 5600x, because simply newer...
But 3700x has better support in kernel 5.4 (ecc reporting)... 5600x needs kernel 5.11 to run more optimal.

However, both are good. Take the one you like and probably decide by the money you pay. Probably 3700, but with ssd raid 10 instead of ssd raid 5... (Cause you can buy one more ssd, while saved on cpu, or more ram... Both brings benefit) xD

EDIT: More threads will make more VMs (and the host) run more smoothly (at the same time). Zen 3 has better performance per thread than Zen 2. Proxmox support for Zen 3 if not perfect yet (search this forum). If you want to do PCIe passthrough, look for a X570 motherboard. If you need more PCIe lanes (for passthrough), look into ThreadRipper, EPYC, Xeon platforms. Make sure to get enough RAM to run all your VMs. Probably motherboard and memory will have more impact on your experience than the choice between 5600X and 3700X.
