The Mac Pro "Twelve Core" 2.4 (Mid-2012/Westmere) is powered by dual 2.4 GHz Six Core 32-nm Xeon E5645 (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 can be equipped with two 2.66 GHz Six Core Intel Xeon X5650 or two 3.06 GHz Six Core Intel Xeon X5675 processors for a total of twelve cores for both of these custom configurations.
By default, this model is configured with 12 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.
Please note that the "Mid-2012" Mac Pro models practically are identical to the "Mid-2010" models before them, but there are some differences in terms of specs and identifiers and EveryMac.com has documented them as their own models, accordingly.

||June 11, 2012
||October 22, 2013*
||The "Introduction Date" typically refers to the date a model was introduced via press release, although no press release was issued for this model. The "Discontinued Date" refers to the date a model either was replaced by a subsequent system or production otherwise ended.
*This model was discontinued in the US on October 22, 2013. However, Apple stopped online orders in the EU on February 18, 2013, and discontinued it altogether in the EU on March 1, 2013.

||2 (12 Cores)
||*These Geekbench 2 benchmarks are in 32-bit and 64-bit modes, respectively.
Geekbench 2 benchmarks reflect results as submitted to the Geekbench website. Higher numbers are better. Individual user-submitted benchmarks can vary, but an average can be useful to get an idea of the relative performance of different Macs. You also might be interested in combing through all Geekbench user-submissions for Macs with the MacPro5,1 Model Identifier, which may include multiple models.

||6 Core Xeon E5645 x2
||The 64-bit 32-nm Xeon E5645 (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 2.67 GHz.
