(2) (POWER) (Performance Optimization With Enhanced RISC) A RISC-based CPU architecture from IBM used in its pSeries, iSeries and i5 computer lines. The PowerPC, enhanced by Motorola and Apple, is a single-chip version of the POWER architecture. POWER CPUs and PowerPC CPUs share a common instruction set that provides binary compatibility in some cases or compatibility by recompilation. Following is the evolution of POWER chips. See PowerPC, iSeries and pSeries.
