CPU Performance

Multi-core processor - A processor with more than one core (processor circuit) which means it can fetch and execute more than one instruction at a time.

Overclocking - Running a CPU at higher clock speed than was intended.

Clock speed - The speed at which the processor carries out instructions, measured in Megahertz (MHz) or  Gigahertz (GHz).

CPU cache - Memory buffer on the processor that stores instructions which have been fetched before and allows them to be fetched more quickly the next time.
