Looking to punch up the processing power your mirror drive door-equipped Power Mac G4? CPU upgrade maker Giga Designs on Tuesday
announced a new processor upgrade
for those systems that uses two Freescale 7455B CPUs clocked at up to 1.42GHz. The system features 2MB of Level 3 cache per processor, and operates at 1.42GHz on 167MHz bus systems or 1.4GHz on 133MHz bus systems. Compatible Macs include the original mirror drive door-equipped Power Mac G4 made in 2002, the FireWire 800 model, and those made in 2003. The upgrade features a copper cooler with an 80mm fan which Giga Designs claims lets the Mac run quieter. No software or firmware upgrades are required to get it to work. Giga Designs expects to deliver the new model in November, 2004 for a suggested retail price of US$699.
