performance core

performance core

A CPU core that is designed for maximum performance. Also called a "P core." Contrast with "efficiency core" (E core), which delivers less raw performance but is less power hungry to conserve battery. The performance difference is obtained by varying voltages and clock speeds. For example, Apple's M1 system-on-chip (SoC) has four performance cores and four efficiency cores. See big.LITTLE and ARM Mac.
