Power Mac G5

Introduced: June 2003
Terminated: June 2004


The Power Mac G5 was housed in a new and innovative aluminum casing.  There were three different configurations in the initial release.  The low-end configuration ran at 1.6Ghz, had an 80Gb hard drive and 256Mb of RAM.  Midrange configuration ran at 1.8Ghz, had a 160Gb hard drive and 512Mb of RAM.  The high-end configuration ran dual 2.0Ghz, had a 160Gb hard drive and 512Mb of RAM.  The Power Mac G5 had PCI-X slots and 8X AGP slot.  It also had a Serial-ATA bus and a front-side bus speed.  All configurations had a SuperDrive.


Launched as the fastest personal computer ever built, the Power Mac G5 represented a major leap forward.  Now working with IBM for the processor instead of Motorola, the fifth generation of the PowerPC based computers was far more advanced and had a number of enhancements to the motherboard.  The new aluminum case was stylish and well designed.

Apple’s newest professional level desktop was $1,999 for the low-end configuration, $2,399 for the midrange and $2,999 for the high-end dual processor configuration.

Some early versions with the dual processor were noted for having annoying noise problems.

  • It was nice to remind me about this version, it is already forgotten and I don’t know if many people still have one like this on their homes. Masini de inchiriat

  • Apple’s product is too expensive yet in good quality which I prefer most. Apple is a known company and knowing more about the history of their developments with their products sounds so interesting to me. Virility EX
