VMware ESX – Sockets and Cores (Logical Processors)

KB ID 0001124 

Problem

While explaining to a client the difference between Sockets, Cores, Logical processors, I had to revisit this post today, so I updated it for vSphere7

Calculating Sockets and Cores

sockets and cores

Logical Processors, Cores and Sockets

 Essentially;

A: Processor Sockets: The Physical amount of CPUs on the motherboard.

B: Cores Per Socket: For a dual core processor this would be 2, triple core=3, quad core = 4, hex core = 6, octa core=8, deca core=12, etc.

C: Logical Processors: This is the amount of sockets, multiplied by the cores, and if Hyperthreading is enabled on the processors (see above), then that figure is doubled.
