The Apple Power Macintosh G5/1.8 DP (PCI), along with the Power Macintosh G5/2.0 DP (PCI-X 2) and Power Macintosh G5 2.5 DP (PCI-X), is a member of the first Mac series to use the 90 nm 64-bit PowerPC 970fx (G5) processor, which uses less power and generates less heat than previous chips.

The Power Macintosh G5/1.8 DP (PCI) features dual 1.8 GHz PowerPC 970fx (G5) processors each with an optimized AltiVec "Velocity Engine" vector processing unit and 512k level 2 on-chip cache. It shipped configured with 256 MB of 400 MHz PC3200 DDR SDRAM, an 80.0 GB (7200 RPM) Serial ATA hard drive, an 8X 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. This model does not support PCI-X.

Like the earlier models, the Power Macintosh G5/1.8 DP (PCI) uses the same "anodized aluminum alloy" case 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.
