i know in desktop PC, i have Core 2 Quad, Its single processor computing unit and 4 cores in it... if im not wrong.
But i want to ask if i rent Xeon E3 CPU server in datacenter. This server main board has 4 physical CPU units and in each 2 cores? (total 8 cores)? Or how it is?

Update: possibly the best is to verify on vendor website by searching for the CPU name:
