CPU
CPU	Single quad-core Xeon W3520 at 2.66 GHz or W3540 at 2.93 GHz; the current support sheet also includes the later 3.33 GHz W3580 option with Turbo Boost up to 3.6 GHz. Dual-processor choices are two quad-core E5520 at 2.26 GHz, X5550 at 2.66 GHz or X5570 at 2.93 GHz (the latter up to 3.33 GHz). Exact processor identities are cross-checked with EveryMac and Intel's server processor table. All have 8 MB L3 cache per processor and Hyper-Threading; dual systems have eight physical cores and sixteen threads. Processor count means physical sockets, and chip cores/threads are per processor.	Dual models have one physical dual-core PowerPC G5 at 2 or 2.3 GHz. Quad has two physical dual-core processors at 2.5 GHz, four cores in total. Each core has 1 MB L2 cache. Front-side bus per physical processor is 1, 1.15 or 1.25 GHz respectively. Macworld’s exact Quad review describes its liquid cooling.
GPU
GPU	NVIDIA GeForce GT 120 with 512 MB GDDR3 or ATI Radeon HD 4870 with 512 MB GDDR5. Factory upgrades include two, three or four GT 120 cards, with memory per card.

The current factory tables list 3, 6, 8, 12 or 16 GB for single systems and 6, 8, 12, 16 or 32 GB for dual systems. The original launch announcement limited the single-processor model to 8 GB; the higher current support limit is distinguished here.	Stock 512 MB PC2-4200 DDR2 at 533 MHz, installed in matched pairs. Up to 16 GB supported; ECC configurations available from 1 GB. Rows retain the stock drive and graphics at base and maximum supported memory.
Storage type
Storage type	Four 3.5-inch cable-free bays with independent 3 Gb/s SATA channels and included carriers. Factory order tables list a 640 GB 7200 rpm drive with 16 MB cache or a 1 TB 7200 rpm drive with 32 MB cache; configurations represent one selected drive. The current support sheet additionally lists 2 TB drives and a 2 TB upgrade kit, allowing up to 8 TB with four drives, versus the launch announcement's 4 TB maximum. Optional Mac Pro RAID Card has 512 MB cache and a 72-hour backup battery. Standard 18x double-layer SuperDrive; optional second optical drive.	Stock 160 GB on dual-core 2 GHz and 250 GB on dual-core 2.3 GHz and Quad. 7200 rpm Serial ATA drives; two internal bays. Optional one or two 500 GB drives. One optical bay with 16x SuperDrive supporting dual-layer DVD+R recording.
Expansion slots
Expansion slots	Double-wide PCI Express 2.0 x16 graphics slot and three open full-length slots (one x16 and two x4), with 300 W combined maximum. All slots mechanically accept x16 cards; PCI and PCI-X cards are unsupported. Optional dual- or quad-channel 4 Gb Fibre Channel card.	PCI Express: occupied x16 graphics slot, two open x4 slots and one open x8 slot. Older PCI and PCI-X expansion cards cannot be reused in these slots.
