What are the differences between the 'Mid-2012' Mac Pro models and the 'Mid-2010' Mac Pro models that they replaced? Are there any differences? How can these lines be differentiated from one another? In as few words as possible, the differences between the 'Mid-2012' Mac Pro models -- the,,,, and -- and the 'Mid-2010' models replaced -- the,,,,, and -- amount to little more than updated processors, double the standard memory, and pricing changes. The Mac Pro continues to be all about expandability and customization. There are literally billions of configuration Longer bars are better. Blue bars in italics represent reference systems. Macworld Lab testing by James Galbraith Quad-core and 8-core Mac Pro (Mid 2010) benchmarks. More bluntly, -- who was a member of the development team --: The specs for the 'new' [Mid-2012] Mac Pro had hardly changed, except for a tiny, inconsequential processor clock bump. Still no Thunderbolt, still no USB 3.0, no SATA III or RAM speed improvements - it seems like it's stuck in time in 2010. The only thing that's still high-end about it is the bloated price. ![]() Nevertheless, these minor differences still are worth noting and the two lines do have some different identifiers, which definitely is useful for precise identification on the used market.

All 'Mid-2010' and 'Mid-2012' Mac Pro models alike have 5 USB 2.0 ports (two on the front and three on the back), 4 Firewire '800' ports (two on the front and two on the back), dual Gigabit Ethernet ports, a front-mounted headphone jack, optical digital audio Toslink in/out and analog stereo in/out minijacks, Bluetooth 2.1+EDR and AirPort (802.11a/b/g/n). By default, all models also have two Mini DisplayPorts -- capable of passing an audio signal as well as video -- and one dual-link DVI port provided by the standard ATI Radeon HD 5770 graphics card. Identification Differences The 'Mid-2010' and 'Mid-2012' Mac Pro models share the as well as the. The Model Number is shared with the 'Early 2009' line as well, and is not 'close enough' for the purpose of identification. However, the 'Mid-2010' and 'Mid-2012' models share the same,,, and other internal components and the model identifier is close enough to perform any upgrades on these models. To locate the model identifier, select 'About This Mac' under the Apple Menu on your computer and click the 'More Info.' If the Mac Pro is running OS X 'Lion' (10.7) or later, click the 'System Report' button after clicking 'More Info.' Even better, the 'Mid-2010' and 'Mid-2012' Mac Pro lines can be uniquely identified externally by the and, respectively. The EMC number is located on the back of the system in small type and this is the easiest identifier to use. As always, EveryMac.com has carefully hand documented these identifiers for future reference. EveryMac.com's feature -- as well as the -- additionally can identify the 'Mid-2010' and 'Mid-2012' Mac Pro models by their serial numbers. More information about specific identifiers is provided in EveryMac.com's extensive section. Internal Similarities & Differences Internally, each of the 'Mid-2010' and 'Mid-2012' Mac Pro models support 'Hyper-Threading' -- which 'allows two threads to run simultaneously on each core' -- and 'Turbo Boost' -- which 'automatically boosts the processor speed based on workload' (so if an application is only using one core it will automatically increase the speed of the core in use and turn off the unused cores). All models have a 'QuickPath Interconnect' (QPI) system described as a 'bidirectional, point-to-point connection' that provides 'quick access to the disk, I/O, and other Mac Pro subsystems' in lieu of a 'traditional' system bus as well, but the speed varies on different models. Models with Quad Core processors from both lines use 1066 MHz DDR3 ECC SDRAM (PC3-8500) memory whereas models with Six Core processors use 1333 MHz DDR3 ECC SDRAM (PC3-10600) memory. Internal expansion for all 'Mid-2010' and 'Mid-2012' Mac Pro systems includes four that support Serial ATA 3Gb/s drives (one occupied by a 1 TB hard drive by default), have two 5.25' (one occupied by an 18X DL 'SuperDrive' by default), and have four PCI Express 2.0 (two x16 slots and two x4 slots with one x16 slot occupied by an ATI Radeon HD 5770 with 1 GB of dedicated GDDR5 memory).
