Apple Power Mac G5The Apple Power Macintosh G5/2.0 DP (PCI-X), along with the Power Macintosh G5/1.6 and Power Macintosh G5 1.8, is a member of the first Mac series to use the 64-bit PowerPC 970 (G5) processor, and consequently are arguably the first "desktop" computers to use 64-bit chips. In addition to higher clock speeds, the PowerPC 970 (G5) has a "new execution core that features massively parallel computation for an unprecedented 215 in-flight instructions", and the Power Macintosh G5 uses a new system architecture as well. Together this combination results in major speed gains compared to earlier Apple systems.

The Power Macintosh G5/2.0 (PCI-X) features dual 2.0 GHz PowerPC 970 (G5) processors each with an optimized AltiVec "Velocity Engine" vector processing unit and 512k level 2 on-chip cache. It shipped configured with 512 MB of 400 MHz PC3200 DDR SDRAM, a 160.0 GB (7200 RPM) Serial ATA hard drive, a 4X DVD-R/CD-RW "SuperDrive", and an ATI Radeon 9600 Pro (AGP 8X Pro) video card with 64 MB of DDR SDRAM. In addition to including FireWire "400" and "800", ADC, DVI, support for AirPort Extreme (802.11g) and Bluetooth 1.1, the Power Macintosh G5 also introduces USB 2.0 (on the Mac) and optical digital audio in/out. Additionally, this model and the mid-range Power Macintosh G5 1.8 introduced PCI-X slots.
