What are the Mac Pro models?

The Mac Pro Model 1,1 was released in August of 2006. This 32-bit machine featured the Intel 5000X chipset, as well as two 2.66 GHz dual core Intel Xeon processors. Mac Pro DDR2 RAM 667MHz came with an original configuration of 1GB (2x512MB), and an nVidia GeForce 7300 graphics card with 256 MB or GDDR3 SDRAM. It included a 250 GB Serial ATA hard drive, a 16x SuperDrive optical drive, and uses OS X 10.7 Lion, although one can upgrade to Mountain Lion.

Model ID 2,1 (DDR2 667MHz): Out in April of 2007, this device is very similar to the 1,1. The only real difference here is the optional 3 GHz quad core processor.

Model ID 3,1 (DDR2 800MHz): Released in Jan of 2008, the machine is 32-bit in Mac OS X client and 64-bit in Mac OS X server. They include the Intel 5400 chipset, two 2.8 GHz Intel quad core processors, a 1600 MHz bus, and 2 GB of 800 MHz DDR2 memory. For graphics, it has an ATI Radeon HD 2600 XT with 256 MB of GDDR3 SCRAM. The hard drive is a 320 GB Serial ATA. It features the same type of optical drive as the previous models, and it operates on the Mountain Lion OS.
