CPU vs. Core: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 15, 2024
CPU (Central Processing Unit) is the primary component of a computer that performs calculations; a core is a single processing unit within a CPU, capable of executing tasks.

Key Differences

The CPU, or Central Processing Unit, is the main chip in a computer responsible for carrying out instructions of a computer program. A core, within the CPU, is an individual processing unit that can execute these instructions independently.

CPU

The central processing unit, that part of the electronic circuitry of a computer in which the arithmetic and logical operations are performed on input data, which are thereby converted to output data; it is usually located on the mainboard, or motherboard, of a computer. The CPU and the memory form the central part of a computer to which the peripherals are attached. Most personal computers as of 1998 had only one CPU, but some computers may have more than one CPU.

Core

(computer hardware) An individual computer processor, in the sense when several processors (called cores or CPU cores) are plugged together in one single integrated circuit to work as one (called a multi-core processor).
I wanted to play a particular computer game, which required I buy a new computer, so while the game said it needed at least a dual-core processor, I wanted my computer to be a bit ahead of the curve, so I bought a quad-core.
