PowerPC G4


PowerPC G4 is a designation used by Apple Computer to describe a fourth generation of PowerPC microprocessors. Apple has applied this name to various different (though closely related) processor models from Freescale, a former part of Motorola. Macintosh computers such as the PowerBook G4 and iBook G4 laptops and the Power Mac G4 and Power Mac G4 Cube desktops all took their name from the processor. A PowerPC G4 was also used in the eMac, first-generation Xserves, first-generation Mac minis, and the flat-panel iMac before the introduction of the G5 processor. Apple completely phased out the G4 series for desktop models after it selected the 64-bit IBM-produced PowerPC 970 processor as the basis for its PowerPC G5 series.
