由摩托罗拉公司和苹果公司联合开发的高性能32位和64位RISC微处理器系列,以与垄断PC机市场的Intel微处理器和微软公司的软件相竞争。PowerPC微处理器1994年推出。因此,基于PowerPC的计算机通过在PowerPC上运行一个特殊程序就可运行DOS或传统的Macintosh软件,这种特殊程序可分别识别和执行80386或68030CPU的机器指令。 IBM以前跟Intel竞争过桌面处理器市场，但由于市场策略不当等原因，IBM没赚到什么钱，于是决定退出桌面市场。POWER系列处理器是它退出桌面市场后才开发出来的服务器用处理器，苹果电脑用的处理器只是Power系列里的一种，据说是IBM为苹果特制的简化版本，而苹果独一无二的经营理念使苹果电脑与其它PC都不兼容，所以目前的Power系列处理器不能用于桌面PC。目前苹果电脑因PowerPC处理器不适合苹果发展而转而使用Intel处理器。

PowerPC
- abstract: PowerPC (an acronym for Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a RISC instruction set architecture created by the 1991 Apple–IBM–Motorola alliance, known as AIM. PowerPC, as an evolving instruction set, has since 2006 been renamed Power ISA but lives on as a legacy trademark for some implementations of Power Architecture based processors.
