Original models

The original Apple Power Mac G4 was introduced at the Seybold conference in San Francisco on 31 August 1999, with 400 MHz, 450 MHz and 500 MHz configurations available. In October 1999, Apple was forced to postpone the 500 MHz due to poor yield of the 500 MHz chips. In response, Apple “speed dumped” the processor speed in each configuration by 50 MHz but caused some controversy by not decreasing the price of the machines.

The early 400 MHz (later 350 MHz) PCI-based "Yikes!" version used an motherboard identical to the one used in Power Macintosh G3 (Blue & White) computers (minus the ADB port), in a "graphite" colored case and with the new PowerPC 7400 (G4) CPU. The higher-speed (Sawtooth) models used a greatly modified motherboard design with AGP 2x graphics (replacing the 66 MHz PCI slot). In December 1999, the entire Power Mac G4 line was updated to the AGP motherboard. An open Power Macintosh G3 case, showing the logic board placement on the hinged door. ...

The machines featured DVD-ROM drives as standard. The 400 MHz and 450 MHz versions had 100 MB Zip drives as standard equipment, and as an option on the 350 MHz Sawtooth. This series had a 100 MHz System bus and four PC100 SDRAM slots for up to 1.5 GiB of RAM. The AGP Power Macs were the first to include an AirPort slot and DVI video port.

Apple's name for all these early AGP models is Power Mac AGP Graphics. The code name Sawtooth was used.


The design was updated at the Macworld Expo New York on 19 July 2000; the new revision included dual-processor 450 MHz and 500 MHz versions, and a low-end single CPU 400 MHz model. It was also the first personal computer to include Gigabit ethernet as standard. Most people saw this revision as a stopgap release, because higher clocked G4s were not available; the G4’s Motorola XPC106 “Grackle” PCI/Memory controller prevented the G4 from hitting speeds higher than 500 MHz. The dual 500 MHz models featured DVD-RAM and Zip drives were optional on all models. These models also introduced Apple's proprietary Apple Display Connector video port.

Four-slot models

A new line with a revamped motherboard but the familiar "Graphite" case debuted on 9 January 2001. New features included a fourth PCI slot, a 133 MHz system bus, an improved 4X AGP slot, and a new "digital audio" sound system, giving the series its name "Power Mac Digital Audio". The models were offered in 466 MHz, 533 MHz, dual 533 MHz, 667 MHz and 733 MHz configurations, the latter two using a newer PowerPC 7450 processor. The number of RAM slots were reduced to three, accommodating up to 1.5 GB of PC133 SDRAM. January 9 is the 9th day of the year in the Gregorian calendar. ... 2001: A Space Odyssey. ...

"Quicksilver" Power Mac G4

At Macworld Expo New York on 18 July 2001, a new line debuted featuring a cosmetically redesigned case known as "Quicksilver", but only minor technical changes. It was available in 733 MHz, 867 MHz and dual 800 MHz configurations. The 733 MHz model was notable for not having a level three cache.

The design was updated on 28 January 2002 with 800 MHz, 933 MHz and dual 1 GHz configurations, becoming the first Mac to reach 1 GHz. Again, the low end 800 MHz model did not include any level three cache. This graphics in this series were provided by a nVidia GeForce 4MX card.

"MDD" Power Mac G4

Another generation of Apple Power Mac G4s was introduced on 13 August 2002, featuring both a new Xserve-derived DDR motherboard architecture and a new case design, known as "Mirrored Drive Doors" (MDD). All models were sold in dual processor configurations running at 867 MHz, 1 GHz or 1.25 GHz. As with the Xserves, the PowerPC 7455 CPU used does not have a DDR frontside bus, meaning the CPU could only use at most 50% of the new system's theoretical memory bandwidth, providing no improvement over previous models. The rest was available to the graphics card and I/O systems. A single processor 1.25 GHz model would be the last Power Mac G4 the company offered to the public after the announcement of the new Power Mac G5, introduced in June 2003.

The models were noted for their noisiness, earning them the unofficial designation "Windtunnel G4" in some circles. Noise complaints became such a problem that Apple later replaced the machine's power supply (PSU) and primary cooling fan with quieter versions, and initiated a voluntary do-it-yourself (DIY) replacement scheme for all previously sold machines. At least some MDD models also have a design flaw resulting in noise in the audio-out, picking up interference from the mouse, graphics card, hard drive and other hardware. According to Apple, this is a ground loop issue, and only occurs when used with professional balanced signal audio equipment [1], however some audio experts have contended it is due to shielding defects on the motherboard and affects all equipment [2].

The last real update to the Power Mac G4 line was on 28 January 2003 offering dual 1.42 GHz PowerPC 7455 processors, with features not seen in previous DDR models: built-in FireWire 800 connector, optional integrated Bluetooth, and optional integrated AirPort Extreme.

With the launch of the Power Mac G5 on 23 June 2003, Apple quietly re-introduced the August 2002 Power Mac G4 because of perceived demand for Mac OS 9 machines. Between that, its low price-tag, and the delayed availability of Power Mac G5s, it proved a strong seller for a relatively short time. Production stopped on 9 June 2004 and the remaining inventory was liquidated. Power Mac G5 The Power Mac G5 is Apple Computers name for models of the Power Mac which contain the PowerPC G5 CPU.
