Which one rather a Core or threads on Proxmox?

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.
