Proxmox CPU allocation with P and E cores?

[gogito]

Hey guys, how does Proxmox handle the P and E cores when allocating? For example, on a 13900K, I will have 8p and 16e => 36threads => 36 vCPU. When creating a VM, I input 8 cores for the VM. How would that behave performance wise?

Will it get maximum 8 P cores?

Or will it use CPU % like 8/36 => 22% total cpu resources?

You might be disappointed, but no such special magic. There's this hands-on experience of someone you may find helpful:
