This model was offered as a custom configuration of the Mac Pro "Eight Core" 2.4 (2010/Westmere). However, this system has significant technical differences, and is documented as its own model, accordingly.
The Mac Pro "Twelve Core" 2.66 (Mid-2010/Westmere) is powered by dual 2.66 GHz Six Core 32-nm Xeon X5650 (Westmere) processors with a dedicated 256k of level 2 cache for each core and 12 MB of "fully shared" level 3 cache per processor. It also could be equipped with other dual Six Core processors, but these are documented as their own models for convenience.
By default, this model is configured with 6 GB of 1333 MHz DDR3 ECC SDRAM, a 1 TB (7200 RPM, 32 MB cache) 3Gb/s Serial ATA hard drive, an 18X dual-layer "SuperDrive" and an ATI Radeon HD 5770 graphics card with 1 GB of GDDR5 memory.
Expansion includes two external 5.25" "optical" bays (one free by default), four internal 3.5" "cable-free, direct attach" hard drive bays (three free by default), and four PCIe 2.0 slots (one free PCIe 2.0 x16 slot and two free PCIe 2.0 x4 slots with the default single graphics card installed).
Ports include five USB 2.0 ports, four Firewire "800" ports, dual Gigabit Ethernet, two Mini DisplayPorts and a dual-link DVI port, among others. AirPort Extreme (802.11a/b/g/n) and Bluetooth 2.1+EDR is standard.
Although the "Mid-2010" models look essentially the same externally as the "Early 2009" models, all "Mid-2010" models are equipped with faster graphics and there are significant technical differences for higher-end "Westmere" models as well with faster processors and as many as twelve cores (two six core processors) via custom configuration.

| Processor Speed: |
2.66 GHz |
Processor Type: |
6 Core Xeon X5650 x2 |
| Details: |
The 64-bit 32-nm Xeon X5650 (Westmere) processor has six independent processor "cores" each with a dedicated 256k level 2 cache, 12 MB of "fully shared" level 3 cache, an integrated memory controller, and "a 128-bit SSE4 SIMD engine". It also supports "Hyper-Threading" -- which "allows two threads to run simultaneously on each core" (so Mac OS X recognizes twenty four total cores on this model, twelve real and twelve virtual) -- and "Turbo Boost" -- which "automatically boosts the processor speed based on workload" (so if an application is only using one of the four cores it will automatically increase the speed of the core in use and turn off the unused cores), in this case up to 3.06 GHz.
