- 2003 June: Initial release at speeds of SP 1.6, SP 1.8, DP 2.0 GHz.
- 2003 November: DP 1.8 replaces SP 1.8 GHz; a price reduction on SP 1.6 GHz.
- 2004 June: 90 nm DP 1.8, DP 2.0 and DP 2.5 GHz replace all previous models. The 2.5 GHz model is notable as the first major PC with liquid cooling included as stock.
- 2004 October: A new SP 1.8 reintroduced, with a slower, 600 MHz FSB (front-side bus), PCI bus, based upon the iMac G5's architecture (U3lite and Shasta chips). Apple's official name for this machine is "Power Mac G5 (Late 2004)".
- 2005 April: CPU speed increased: DP 2.5 GHz → DP 2.7 GHz (PCI-X, LC), DP 2.0 GHz → DP 2.3 GHz (PCI-X), DP 1.8 GHz → DP 2 GHz (PCI). Newly introduced features were the 16x dual-layer SuperDrives across the line and increased storage, up to 800 GB for the higher-end models. The 1.8 GHz SP was not modified.
- 2005 June: The SP 1.8 model was discontinued in the United States.
- 2005 July: The SP 1.8 model was discontinued in Europe.
- 2005 October: Shift to dual-core processors: DP 2.0 GHz → DC 2.0 GHz, DP 2.3 GHz → DC 2.3 GHz, DP 2.7 GHz → DP DC 2.5 GHz (termed a Quad Power Mac G5, with four CPU execution cores and more reliable liquid cooling), all with DDR2 memory, and PCI Express expansion in place of PCI-X. The older PCI-X, DP 2.7 GHz model remained available for a while, but the slower speed single-core models were discontinued immediately.
- 2006 August: The Power Mac is replaced by its Intel successor, the Mac Pro.

Famous quotes containing the words product and/or history:
“Perhaps I am still very much of an American. That is to say, naïve, optimistic, gullible.... In the eyes of a European, what am I but an American to the core, an American who exposes his Americanism like a sore. Like it or not, I am a product of this land of plenty, a believer in superabundance, a believer in miracles.”
—Henry Miller (1891–1980)
“In history an additional result is commonly produced by human actions beyond that which they aim at and obtain—that which they immediately recognize and desire. They gratify their own interest; but something further is thereby accomplished, latent in the actions in question, though not present to their consciousness, and not included in their design.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
