CPU vs Core Vs Socket

We often get confused between CPU vs Core Vs Socket and How to find that in Windows. Here is my attempt at explaining those terms and how we can find them in Windows

Physical CPU

It is the physical Processor on the server.Each CPU is assigned to one socket

Core

Each Physical CPU consist of single or Multiple Processing unit which are called Core of the Physical CPU. A Physical CPU could be dual core,quad core .It is the core which execute all the program  instructions. In multiple core processor,multiple programs can be executed in parallel providing better throughput.We see lots of these in market today

Socket

It is the physical connector on the motherboard in which physical CPU is fit in. Desktop computer usually have one Socket while server have multiple socket to accommodate multiple physical CPU

Hyper-threading( Logical CPU)

This concept was introduced by Intel to parallization of computation. This is intel properierty Simultaneous Multi threading implementation.Each core is presented as two logical . Each logical processor work independently from the other logical processor sharing the same physical core and can process a thread.

So if you have 4 core, then it means 8 logical CPU.

Here is the snapshot from the Laptop Computer

You can retrieve the CPU,Core,socket information from Windows operating systems as below also

(1) WMIC CPU Get /Format:List

(2) Click on Run and type MSINFO32

Hope you like short and to the point post on CPU vs Core Vs Socket
