The Power Macintosh G5 Dual Core (2.0) is powered by a single "dual core" 2.0 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 1.0 GHz frontside system bus. It shipped configured with 512 MB of 533 MHz PC2-4200 DDR2 SDRAM, a 160 GB (7200 RPM) Serial ATA hard drive, a reported "16X" dual-layer "SuperDrive", and a NVIDIA GeForce 6600 LE video card with 128 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 (2.0) 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.

The PowerPC 970MP "G5" has two independent 2.0 GHz processor "cores" on a single silicon chip. It also includes dual optimized AltiVec "Velocity Engine" vector processing units (one per core), four double-precision FPUs (two per core), and on chip level 2 cache on each core.
Like all PowerPC "G5" processors, the PowerPC 970MP "G5" has 64-bit data paths and registers with native support for 32-bit application code. Apple also reports that each core of the 970MP has a "parallel data structure supporting up to 215 simultaneous in-flight instructions, [and] simultaneous issue of up to 10 out-of-order operations." Each core likewise has a "dual-pipeline Velocity Engine for 128-bit single-instruction, multiple-data (SIMD) processing [and] advanced three-stage branch-prediction logic."

2nd Display Support:
2nd Max. Resolution:
The default graphics card can support a second display with a maximum resolution of 1920x1200 using the single-link DVI port (assuming the dual-link DVI port is being used for the primary display). The build-to-order NVIDIA Quadro FX 4500 graphics card with 512 MB of GDDR3 SDRAM has two dual-link DVI ports and is capable of powering two 2560x1600 displays, like the 30-inch Apple Cinema Display models.

6X DL "SuperDrive"
Apple reports that this "16X" DVD+R DL/DVD±RW/CD-RW SuperDrive "writes DVD-R discs at 16x speed, writes DVD+R DL discs at up to 6x speed, reads DVDs at up to 16x speed, writes CD-R and CD-RW discs at up to 24x speed, [and] reads CDs at up to 32x speed." It uses an Ultra ATA/100 bus.

2 (400), 1 (800)
The "Multiple Core" Power Mac G5 models have four USB 2.0 ports on the system (one on the front panel and three on the back), two Firewire "400" ports (one on the front and one on the back), and one Firewire "800" port on the back. Apple also advertised "two USB 1.1 ports on included keyboard".
3 PCIe, AP/BL
This model has "two open full-length four-lane PCI Express slots", "one open full-length eight-lane PCI Express slot", a 16-lane PCI Express slot that is occupied by the graphics card, as well as expansion slots for AirPort Extreme (802.11g) -- antenna internal -- and Bluetooth 2.0+EDR.
