These were the first Macs to include 16x SuperDrives. GHz CPUs and were the last Macs to use PCI or PCI-X expansion These dual-processor models had 2.0, 2.3, and 2.7 Pushed the PowerPC G5 processor to 2.7 GHz - the highest clock speed ofĪny pre-Intel Mac. Has the slower one-third speed memory bus, the newer Nvidia GeForceįX5200 Ultra video card, and an 8x SuperDrive. Nvidia GeForce FX5200 video card, and a 4x SuperDrive. The 2003 model has the faster half-speed memory bus, an This model had PCI slots and a 4 GB memoryīuyers should pay attention when buying a 1.8 GHz single processor This was the first G5 to run the memory bus as one-third ofĬPU speed instead of one-half, yet it used the same 400 MHz PC3200 RAMĪs the other models.

In October 2004, Apple introduced a less costly Power Mac G5 with a single 1.8 GHzĬPU.
As before, the entry-level Power Mac had a 4 GB memoryĬeiling and PCI slots while the faster ones supported up to 8 GB The June 2004 Power Macs all had dual processors (1.8, 2.0, and 2.5 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. Hard drives, which supports transfer rates up to 150 MBps (50% faster

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 With up to nine fans running only when they Whole new hardware design with multiple thermal zones and multiple fans Respectively - and put the 167 MHz memory bus of top-end G4 Macs to The memory bus ran at half this speed - 800, 900, and 1000 MHz and 2.0 GHz speeds, and the top-end model had two CPUs. 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. Logicboards are the most expensive component to repair,įollowed by the power supply. Model is the least reliable, while the second-fastest is the most In each generation, except for the final dual-core one, the fastest 2005), C- (18%, power supply, logicboard or 2003), F (27%, logicboard, optical drive) We also note the two components that failed most G5 models had only been on the market for 8 months. 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
