The Power Macintosh G5 Dual Core (2.3), along with the Power Macintosh G5 Dual Core (2.0) and Power Macintosh G5 "Quad Core" (2.5), are the first and last Power Macintosh G5 models to use dual core PowerPC 970MP (G5) processors, which have two independent processor "cores" on a single silicon chip.

The Power Macintosh G5 Dual Core (2.3) is powered by a single "dual core" 2.3 GHz PowerPC 970MP (G5) processor with dual optimized AltiVec "Velocity Engine" vector processing units (one per core), four double-precision FPUs (two per core), 1 MB of on-chip level 2 cache on each core, and a 1.15 GHz frontside system bus. It shipped configured with 512 MB or 1 GB of 533 MHz PC2-4200 DDR2 SDRAM, a 250 GB (7200 RPM) Serial ATA hard drive, a reported "16X" dual-layer "SuperDrive", and a NVIDIA GeForce 6600 video card with 256 MB of GDDR SDRAM.

Connectivity includes USB 2.0, FireWire "400" and "800", a single-link DVI and a dual-link DVI port, optical digital audio in/out, two independent Gigabit Ethernet ports, and support for AirPort Extreme (802.11g) and Bluetooth 2.0+EDR.

All of the "multiple core" equipped Power Macintosh G5 models have three open PCI-Express (PCIe) expansion slots. The Power Macintosh G5 Dual Core (2.3) uses the same easy-to-upgrade "anodized aluminum alloy" case as all other Power Macintosh G5 models with the same removable side panel for easy access to internal components. Likewise, it is divided into four different thermal zones with nine computer-controlled fans for optimum cooling.
