    No, they do not need to be the same speed either. If you have mismatched processors you enable EVC in your vCenter Cluster.

    We have many different types of server, different specifications of processor, speeds, types, generations in our 50 Server ESXi/ESX Cluster.

    We also have Single CPU, Dual CPU and Quads in the same cluster.
