Steve Jobs toward Intel.) Video cards were somewhat improved, and Apple
To deliver on its 3 GHz promise was the final straw that pushed To 2.5 GHz - a 25% increase in speed, but not quite the 50% boost Jobs predicted that we'd have 3.0 GHz G5s within a year - a promise IBMĪpple added a dual 1.8 GHz model to the line in November 2003. And to the great joy of power users, Steve Theįaster models supported up to 8 GB of RAM, but the entry-level G5 The 1.6 GHz entry-level G5 used the same PCI slots Apple had usedįor years, but the faster models supported the newer PCI-X bus. One very nice feature of these G5s: Apple placedĪ headphone jack, USB port, and FireWire port on the front of theĬomputer where they were much easier to access. The first Power Macs with USB 2.0 ports, which had long been standard Than FireWire), although Apple retained the established Ultra ATA/100īus for SuperDrives throughout the Power Mac G5 range.

In other changes, these were the first Macs to use Serial ATA (SATA) Needed to and only as fast as they had to, the G5s tended to run very

The Original G5īilled as "the world's fastest computer" at release, the June 2003 Power Mac G5 was available Hard drives, optical drives, video cards,Īnd RAM can be replaced inexpensively using third-party components.

Reliability ratings are based on statistics compiledīy MacInTouch in June 2006, at which time the dual-core Power Mac Were far fewer reports of cooling system problems with the 2.5 GHz G5 Reliability, MacInTouch notes that 3-4% of these models hadĬooling-related repairs when the survey was taken in June 2006. Have problems with their cooling systems, particularly coolant leaks. Models, Apple adopted a liquid cooling system.Īll of the 2.5 GHz and 2.7 GHz Power Mac G5 models use liquidĬooling, and the June 2004 2.5 GHz and April 2005 2.7 GHz G5s sometimes For slower models, airĬooling was adequate, controlled by 9 cooling fans, but in faster "thermal zones" inside the G5's tower enclosure. The G5 CPU runs hot, and Apple addressed this problem with multiple Ran their CPUs anywhere from 3.5 to 8.5 times bus speed, which ranged Models ran memory at one-third of CPU speed (in contrast, G4 Power Macs G5 Power Macs ran their memory bus at half of CPU speed, although some Based on IBM's POWER architecture, the newer G5ĬPU cried out for a fast, wide system bus - and Apple provided it. Apple made a big shift when it moved from the G4
