DescriptionEdit

The specifications below are from Apple's "tech specs" page^[1] or developer notes^[2], except where noted.

ProcessorsEdit

  One 2.8 GHz Quad-Core "Bloomfield" Intel Xeon (W3530) processor with 8 MB of L3 cache or two 2.4 GHz Quad-Core "Gulftown" Intel Xeon (E5620) processors with 12 MB of L3 cache or two 2.66 GHz 6-core "Gulftown" Intel Xeon (X5650) processors with 12 MB of L3 cache

Optional 3.2 GHz Quad-Core "Bloomfield" (W3565) or 3.33 GHz 6-core "Gulftown" (W3680) Intel Xeon processors or two 2.93 GHz 6-core (X5670) Intel Xeon "Gulftown" processors

MemoryEdit

The original Mac Pro's main memory used 667 MHz FB-DIMMs; its successor uses 800 MHz FB-DIMMs. The current Mac Pro has 3 GB (three 1 GB) for quad- and 6-core models or 6 GB (six 1 GB) for 8- and 12-core models. These modules are installed in pairs, one each on two riser cards. The cards have 4 DIMM slots each, allowing a total of 32 GB of memory (8 x 4 GB) to be installed Cite error: Closing </ref> missing for <ref> tag.

The bandwidth allocation of the PCIe slots can be configured via the Expansion Slot Utility included with Mac OS X only on the August 2006 Mac Pro. The Mac Pro (Early 2008) has its slots hardwired as follows.

	Default
Slot 4	4x
Slot 3	4x
Slot 2	16x
Slot 1 (Double-Wide)	16x

External connectivityEdit

For external connectivity the system includes five USB 2.0 and four FireWire ports, two of the latter being FireWire 800. Networking is supported with two built-in Gigabit Ethernet ports, while 802.11 a/b/g/draft-n^[3] Wi-Fi is supported via an optional AirPort Extreme card. Bluetooth is now standard. Unlike other recent Mac products, the Mac Pro does not include the infrared receiver needed to use the Apple Remote. However, Front Row is available on all Mac Pros running Mac OS 10.5 (Leopard) or later, and is accessible using the normal ⌘-Esc key combination. The system also provides both digital (optical) and analogue "headphone jacks" for sound in and out, the latter available on both the front and back of the case.

CaseEdit

The exterior of the aluminum case is very similar to that of the Power Mac G5, with the exception of an additional optical drive bay, and a new arrangement of I/O ports on both the front and the back. The case is somewhat larger than another PC of the same generation, at 20 × 18½ × 8 inches, compared to another desktop PC (the Dell Dimension 9100) at 17½ × 17½ × 6½ inches. Some of the difference in height is due to the "handles" on the top and bottom of the case. The case can be opened by operating a single lever on the back, which unlocks one of the two sides of the machine, as well as the drive bays. All of the expansion slots for memory, PCIe cards and drives can be accessed with the one panel removed, and require no tools for installation.

The Xeon processors generate much less heat than the previous dual-core G5s, so the size of the internal cooling devices has been reduced significantly. This allowed the interior to be re-arranged, leaving more room at the top of the case and thereby allowing the drives to double in number. Less heat also means less air to move out of the case for cooling during normal operations; the Mac Pro is very quiet in normal operation, quieter than the already-quiet Power Mac G5^{[4] [5]} , and proved difficult to measure using common decibel meters.^[6]
