Less than a year after unveiling the original Power Mac G5, Apple released a new line of G5 models, each with dual processors and an 8x SuperDrive. As before, the entry level model uses 64-bit PCI slots and only supports up to 4 GB of RAM vs. PCI-X slots and an 8 GB RAM ceiling in the faster G5s.

Making haste slowly, Apple has moved the fastest Power Mac G5 from 2.0 GHz CPUs in 2003 to 2.5 GHz in 2004, and now to 2.7 GHz in 2005. It’s nice to see Apple squeeze nearly 10% more speed fr.

The motherboard architecture uses HyperTransport technology. System memory is so fast (400 MHz RAM on a 900 MHz to 1.25 GHz bus) that Apple doesn’t bother with a level 3 cache.

A headphone jack, a USB 2.0 port, and a FireWire 400 port are located on the front of the G5 for easy access.

The G5 uses an aluminum enclosure that’s vented in the front and back. The case includes four thermal zones and nine fans to handle cooling, each independently controlled for speed. The 2.5 GHz model incorporates a liquid cooling system to keep the CPU from overheating.

Note that the 1.8 GHz model is one of Apple’s entry-level G5s, which means it uses 33 MHz PCI expansion slots instead of 133 MHz PCI-X andhas 4 memory slots instead of 8.

Power Mac G5 Reliability

Reliability ratings are based on statistics compiled by MacInTouch in June 2006, at which time the dual-core Power Mac G5 models had only been on the market for 8 months. Letter grades are based on failure rate: A = 0-6%, B = 7-12%, C = 13-18%, D = 19-24%, and F = 25% or higher. We also note the two components that failed most often.

G5/1.8 dual (June 2004), D+ (19%, logicboard, optical drive)
G5/2.0 dual (June 2004), C- (17%, logicboard, hard or optical drive)
G5/2.5 dual (June 2004), F (26%, logicboard, hard drive)

In each generation, except for the final dual-core one, the fastest model is the least reliable, while the second-fastest is the most reliable. Logicboards are the most expensive component to repair, followed by the power supply. Hard drives, optical drives, video cards, and RAM can be replaced inexpensively using third-party components.
