Usage

The term CPU refers specifically to the main processor of a computer system. - The performance of a computer largely depends on the speed of its CPU. - Modern CPUs can contain multiple processing cores on a single chip.

Advanced Usage
  • CPU-bound: Describes a task or program whose performance is limited primarily by the speed of the CPU, not by other factors like I/O speed.
    • This scientific simulation is CPU-bound, so a faster processor will significantly reduce calculation time.
