Install a couple of X5680 3.33GHz or X5690 3.46GHz Xeons in your 2009-2012 oMP and you will get Geekbench scores of 30-32,000, which equals the extremely costly $7,000 top of the line nMP for half the total cost of the computer. Given that the oMP can be upgraded with even faster CPUs than the fastest Apple ever marketed, the 4-core base nMP’s CPU performance is poor by comparison. The Geekbench chart below is for multi-core performance. Where the nMP falls down in price:performance is in CPU speeds. So that means data speeds are limited to 600mb/s at best in the oMP (using a PCIe SATAIII card) whereas twice that rate should be theoretically possible in the nMP. This Intel data communication technology is a motherboard-only hardware installation and it is extremely unlikely that the aftermarket will ever see a TB-equipped motherboard for the oMP. The nMP adds one feature not available in the oMP – Thunderbolt. Paying Apple or OWC a huge premium for a better CPU suggests you have more money than sense, in which case go for it. The 2013 Mac Pro may still be hard to find but that does not mean the buyer should overpay for the better CPUs available. For an index of all my Mac Pro articles, click here.
