In late 2005, Apple revamped the Power Mac line by moving to the dual-core 970MP processor. These were followed by systems based on the 970FX processor. Initial G5-based Apple computers used IBM's PowerPC 970 processors.
3.1 The Power Mac G5Īpple announced the Power Mac G5-its first 64-bit desktop system-in June 2003. It is also the basis for the first 64-bit dual-core PowerPC processor: the 970MP. We focus on a G5-based system because the 970FX is more advanced, more powerful, and more interesting in general than its predecessors. Moreover, we will discuss a specific PowerPC processor used in these systems: the 970FX. In this chapter, we will look at the system architecture of a specific type of Apple computer: a G5-based dual-processor Power Mac. These systems-the iMac and the MacBook Pro-were based on the Intel Core Duoĭual-core processor line, which is built on 65 nm process technology. The transition was faster than expected, with the first x86 Macintosh computers appearing in January 2006. The move was presented as a two-year transition: Apple stated that although x86-based Macintosh models would become available by mid-2006, all Apple computers would transition to the x86 platform only by the end of 2007. On June 6, 2005, at the Worldwide Developers Conference in San Francisco, Apple announced its plans to base future models of Macintosh computers on Intel processors.

Whereas the G4 processor line is supplied by Motorola, the G3 and the G5 are from IBM. For example, before the G4 iBook was introduced in October 2003, Apple's then current systems included three generations of the PowerPC: the G3, the G4, and the G5. The specific processor used, and the processor vendor. The various PowerPC-based Apple computer families available at any given time have often differed in system architecture, Within the next two years, Apple's entire line of computers moved to the PowerPC. Apple initiated its transition from the 68K hardware platform to the PowerPC in 1994.
