Which one rather a Core or threads on Proxmox?

[rodriguebe]

je ne sais pas, un bon conseil ? ^.. ^

24/12 Go exemple

2x 24 threads = 48 vcpu ?

Ou

Alors

12c x 4 = 48c

Correct ou pas correct ?

Merci s’il vous plaît

Could you provide a bit more context about your use case?

1. Are you comparing different CPU hardware configurations (for example, number of cores vs threads)?
   
   
2. Or are you planning how to allocate vCPUs for VMs in Proxmox?
   
   
3. What kind of workload will run on this host (multiple VMs, containers, databases, HPC, etc.)?

In virtualization environments, physical cores are usually more important than hyper-threads, but the actual impact depends heavily on the workload.

It also depends on the underlying hardware, emulating a 4-socket system on a 2-socket system makes technically no sense and will not help in any way, even if the total core count is identical. The devil is in the details here, so as @pulipulichen already asked already: context matters.

Just the 40 VMs are actually 40 vCPUs, for example.
Threads or cores?
But since I don't know anything about how Proxmox will detect the CPU,
there you go.
Have a good af
