What Is Multi-core Processor?
A multi-core processor is a single computing component with two or more independent actual central processing units (called "cores"), which are the units that read and execute program instructions.
at the same time, increasing overall speed for programs amenable to parallel computing. Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.
Multicore processors may have:
- two cores (dual-core CPUs, for example AMD Phenom II X2 and Intel Core Duo)
- four cores (quad-core CPUs, for example AMD Phenom II X4, Intel's i5 and i7 processors)
- six cores (hexa-core CPUs, for example AMD Phenom II X6 and Intel Core i7 Extreme Edition 980X)
- eight cores (octo-core CPUs, for example Intel Xeon E7-2820 and AMD FX-8350)
- ten cores (for example, Intel Xeon E7-2850), or more
