Mac Pro D. Core Xeon 5130 x2 2006

The Mac Pro "Quad Core" 2.0 (Original), is technically classified as "made-to-order" configuration of the Mac Pro "Quad Core" 2.66 (Original), but is also listed as a separate model for easy reference. Apart from processor, both models share identical specifications.

The Mac Pro "Quad Core" 2.0 features two 2.0 GHz dual core Intel Xeon 5130 processors with 4MB of shared L2 cache per processor, a 128-bit SSE3 vector engine, and 1.33 GHz "64-bit dual independent frontside buses.".

The standard configuration featured 1.0GB of 667 MHz DDR2 ECC "fully-buffered" FB-DIMM memory (with a heatsink design that is a bit different from generic FB-DIMMs), a 250 GB (7200 RPM) 3 Gb/s Serial ATA hard drive, a double-layer 16X "SuperDrive", and a NVIDIA GeForce 7300 GT video card with 256MB of GDDR2 SDRAM, one dual-link DVI port and one single-link DVI port.

Expansion includes two external 5.25" "optical" bays (one occupied by default), four internal 3.5" "cable-free, direct attach" hard drive bays (three available by default), and four PCIe slots (three free with one graphics card installed). Port selection includes dual Gigabit Ethernet, five USB 2.0 ports, two Firewire "400" ports, two Firewire "800" ports, and optical digital audio in/out, and more. AirPort Extreme (802.11g/n), Bluetooth 2.0+EDR, and a modem are optional.

As the entry-level configuration of the first Intel Mac Pro, this 2.0 GHz model offered a more affordable professional platform for users transitioning from PowerPC. [39] Its two dual-core Xeon processors provided adequate performance for many tasks of the era. The highly acclaimed aluminum tower chassis featured exceptional expandability and maintainability, including tool-less access to the interior. [22] However, the FB-DIMM memory generated significant heat, requiring careful attention to cooling. [13] While it paled in comparison to higher-end configurations, it served as an important gateway to the Mac Pro family and allowed users to experience its excellent design philosophy. [39, 42]
