Overview of the Features in Apple’s Mac Pro
The base model comes with a quad-core Intel Xeon processor. Maxed out, it can hold dual Intel Xeon six-core processors, 8TB (8 terabytes) of hard drive space, and 64GB of RAM in eight DIMM slots that incorporate error-correcting codes (ECC) for greater reliability. That’s 12 very fast computers in one box.
Although most Macs are designed with the expectation that their cases will never be opened, the Mac Pro is a major exception. It’s built into a full tower–size case that opens easily to give you access to most Mac Pro components.
Also unlike with other Macs, you have room inside for expansion. The units contain four hard drive bays, and you can install dual SuperDrive optical drives. Apple typically offers several configurations for the Pro with different graphics cards for high, very high, and extreme performance.
Three additional full-length PCI Express (PCIe) slots are available for plug-in cards, which allow expansion of your Mac’s capabilities. These are the same types of expansion cards used in newer PCs. They aren’t compatible with the older PCI, PCI-X, or ISA cards, however.
The PCI Express slots can hold high-speed communications cards, such as Fibre Channel, or as many as three more graphics cards for a maximum of four. A total 300 watts of power are available just to power these cards. The whole Mac Pro can draw 12 amps at 120 volts — half that at 240 volts.
The Mac Pro has two connector panels: a main one in back and a smaller one in front.
The rear panel includes
Three USB 2.0 ports
Two FireWire 800 Mbps ports
Optical digital audio input and output Toslink ports
Analog stereo line-level input and output minijacks
Two independent Gigabit Ethernet ports
The front panel conveniently supplies
Two more FireWire 800 Mbps ports
Two more USB 2.0 ports
Stereo headphone minijack
Bluetooth and Wi-Fi are standard on the Mac Pro.
