Power Mac G5 “Late 2005”


The “Late 2005” Power Mac G5 was the first generation to include a dual-core IBM PowerPC 970MP dual core processor. With a faster 1.15 GHz frontside bus and PCI Express expansions slots, it provided a significant speed increase over it’s dual processor, PCI-X predecessor. The upper-end models utilized a pair of 2.5 GHz dual-core, liquid-cooled processors while the 2.0 GHz and 2.3 GHz lower-end models used a single, dual-core processor and traditional forced-air cooling.

The “Late 2005” generation were the last of the Power Mac G5 models before Apple replaced them with the Intel Xeon-powered Mac Pro.

This machine features a dual-core 2.3 GHz G5 processor, 4.5 GB PC-4200 RAM, 128 MB Nvidia GeForce 6600 graphics card, 500 GB hard disk drive and DVD-R/W “SuperDrive”  optical drive. It was a hand-me-down gift from a friend. It boots into Mac OS X 10.4.3 “Tiger”.
