The first Macs to use IBM’s new dual-core G5 CPUs, the Late 2005 Power Mac G5 Duals and Quad (covered on its own page) provide the processing power of two G5 CPUs on a single chip. Each core has 1 MB of level 2 cache, twice as much as earlier G5s, which further boosts computing power.

Last month, we looked at the Power Mac G4 line, a series of computers that defined the professional workstation for OS X users for many years. In June 2003 — 15 years ago this month — Steve Jobs took the wraps off its successor, the Power Mac G5. The G5 In every way, the Power Mac G5.

Mac Os X Power Mac G5 Specs

Other improvements include the adoption of PCI Express (PCIe) architecture and a 16-lane Nvidia video card, 533 MHz DDR2 memory, and a 16x dual-layer SuperDrive.

The motherboard architecture uses HyperTransport technology. System memory is so fast (533 MHz RAM on a 1.0 or 1.15 GHz bus) and the level 2 cache so large that Apple doesn’t bother with a level 3 cache.

And if a single dual-core G5 CPU isn’t enough for you, there’s always the 2.5 GHz Power Mac G5 Quad, which has two dual-core liquid-cooled CPUs and was Apple’s most powerful PowerPC Mac.

A headphone jack, a USB 2.0 port, and a FireWire 400 port are located on the front of the G5 for easy access, and there are three USB ports on the back, up from two on previous G5 Power Macs.

It’s easier to distinguish the dual-core models from the earlier ones from the back than from the front, as shown in the photo on the left. The Dual and Quad (left) have three USB ports at the bottom of the strip of ports, while earlier models (right) have ethernet and modem at the bottom. The dual-core machines also have a grey plastic strip on the left side.

One oddity of the dual-core Power Mac G5s is that they use a different power connection, known as IEC320 C19, and don’t work with the standard computer power cable, as show in the photo on the right. These models also use a different power supply than earlier G5 Power Macs.

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.

• G5/2.0 dual-core, C- (18%, power supply, logicboard)
• G5/2.3 dual-core, C- (18%, power supply, logicboard or optical drive)
• G5/2.5 quad-core, C- (17%, logicboard, power supply)

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.
