Apple PowerMac G5 Single-Core (PCI-X)
Announced in June 2003, the PowerMac G5 was Apple's long-awaited fifth generation PowerPC-based machine. In an important move, Apple decided to break with Motorola, and use and IBM-designed processor. Motorola had been chronically delayed for both processor design and shipment, and was at least a year away from its fifth-generation PowerPC CPU. Apple and IBM had worked closely together for nearly a year of the PowerPC 970 Processor (publicly referred to as the G5), and the 64-bit PowerMac G5 represented a huge leap forward in both processor and machine design.
Housed in an innovative new Aluminium enclosure, the PowerMac G5 was the first 64-bit consumer-level desktop computer ever sold. It featured either a single 1.6 or 1.8 Ghz processor, or dual 2.0 Ghz processors. It included a variety of motherboard enhancements, including PCI-X slots, and 8X AGP slot, a Serial-ATA bus, and up to 8 GB of RAM. Most impressive of all was the front-side bus speed, which was increased to half of the processor speed-up to 1.0 Ghz. This represented a more than six-fold improvement over the previous PowerMac G4 model.
The PowerPC 970 was a higher-power and higher-temperature chip than its 74xx predecessors, and a considerable amount of engineering went into the cooling system of the PowerMac G5. The case was divided into 4 discreet "thermal zones" each with its own cooling system.
