The PowerPC G5 (called the PowerPC 970 by its manufacturer, IBM) is based upon IBM's 64-bit POWER4 microprocessor. The inside of an air-cooled dual-processor 2003 model The computer was soon dismantled and replaced with a new cluster made of an equal number of Xserve G5 rack-mounted servers, which also used the G5 chip running at 2.3 GHz.

The supercomputer managed to become one of the top five supercomputers that year.

supercluster) known as System X, consisting of 1100 Power Mac G5 towers operating as processing nodes. Steve Jobs stated during his keynote presentation that the Power Mac G5 would reach 3 GHz 'within 12 months.' This would never come to pass after three years, the G5 only reached 2.7 GHz before it was replaced by the Intel Xeon-based Mac Pro, which debuted with processors running at speeds of up to 3 GHz.ĭuring the presentation, Apple also showed Virginia Tech's Mac OS X computer cluster supercomputer (a.k.a. Although somewhat larger than the G4 tower it replaced, the necessity for a complex cooling system meant that the G5 tower had room inside for only one optical drive and two hard drives. Officially launched as part of Steve Jobs' keynote presentation at the Worldwide Developers Conference in June 2003, the Power Mac G5 was introduced with three models, sharing the same physical case, but differing in features and performance. The Mac Pro retained a variation of the G5's enclosure design for seven more years, making it among the longest-lived designs in Apple's history. Three generations of Power Mac G5 were released before it was discontinued as part of the Mac transition to Intel processors, making way for its replacement, the Mac Pro. It was also the first desktop computer from Apple to use an anodized aluminum alloy enclosure, and one of only three computers in Apple's lineup to utilize the PowerPC 970 CPU, the others being the iMac G5 and the Xserve G5. When introduced, it was the most powerful computer in Apple's Macintosh lineup, and was marketed by the company as the world's first 64-bit desktop computer. from 2003 to 2006 as part of the Power Mac series. The Power Mac G5 is a series of personal computers designed, manufactured, and sold by Apple Computer, Inc.
