It’s easier to distinguish the dual-core models from the earlier ones from the back than from the front, as shown in the photo on the left. System memory is so fast (533 MHz RAM on a 1.0 or 1.15 GHz bus) and the level 2 cache so large that Apple doesn’t bother with a level 3 cache.Īnd if a single dual-core G5 CPU isn’t enough for you, there’s always the 2.5 GHz Power Mac G5 Quad, which has two dual-core liquid-cooled CPUs and was Apple’s most powerful PowerPC Mac.Ī headphone jack, a USB 2.0 port, and a FireWire 400 port are located on the front of the G5 for easy access, and there are three USB ports on the back, up from two on previous G5 Power Macs. The motherboard architecture uses HyperTransport technology. Other improvements include the adoption of PCI Express (PCIe) architecture and a 16-lane Nvidia video card, 533 MHz DDR2 memory, and a 16x dual-layer SuperDrive. Each core has 1 MB of level 2 cache, twice as much as earlier G5s, which further boosts computing power. The first Macs to use IBM’s new dual-core G5 CPUs, the Late 2005 Power Mac G5 Duals and Quad ( covered on its own page) provide the processing power of two G5 CPUs on a single chip.
