The Apple Power Macintosh G5/1.8 DP (PCI-X), was introduced to replace the Power Macintosh G5/1.8 (PCI-X) and except for having dual processors and costing US$100 more, effectively is the same.

The Power Macintosh G5/1.8 DP (PCI-X) features dual 1.8 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 a NVIDIA GeForce FX 5200 Ultra (AGP 8X Pro) video card with 64 MB of DDR SDRAM. Connectivity includes USB 2.0, FireWire "400" and "800", ADC, DVI, optical digital audio in/out, and support for AirPort Extreme (802.11g) and Bluetooth 1.1. Like the model it replaced, the Power Macintosh G5/1.8 DP has PCI-X slots.

On first glance, the case looks similar to the case introduced with the "Blue & White" Power Macintosh G3 series crossed with a postmodern cheese grater, but it is actually a completely different design. The "anodized aluminum alloy" Power Macintosh G5 case is divided into four different thermal zones with nine computer-controlled fans for optimum cooling, and features a removable side panel for easy access to internal components. Custom configurations also were available.
