Apple Power Mac G5 The Power Macintosh G5 Dual Core (2.0), along with the Power Macintosh G5 Dual Core (2.3) 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 (2.0) 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.

2.0 GHz PowerPC 970MP (G5)
Details: 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."
