Core


A core may refer to any of the following:

  • A core, or CPU core, is the "brain" of a CPU. It receives instructions, and performs calculations, or operations, to satisfy those instructions. A CPU can have multiple cores.

  • A processor with two cores is called a dual-core processor; with four cores, a quad-core; six cores, hexa-core; eight cores, octa-core. As of 2019, the majority of consumer CPUs feature between two and twelve cores. Workstation and server CPUs may feature as many as 48.

  • Each core of a CPU can perform operations separately from the others. Or, multiple cores may work together to perform parallel operations on a shared set of data in the CPU's memory cache.
