Other World Computing (OWC), in its initial teardown of the new Mac Pro, discovered that the CPU is upgradeable. So they popped in a new CPU and measured a 30 percent improvement in the Geekbench Multi-core score.
OWC's Jarrod and Ron wrote in their blog: "We got our hands on an Intel E5-2667 V2 8-core 3.30GHz with 25MB Cache processor, installed it in the new Mac Pro and have done some benchmarking to get an early look at the performance vs. the stock Apple / Intel E5-1650 V2 6-core 3.50GHz with 12MB Cache model. The testing was done with 64GB of OWC memory installed."
The resulting Geekbench score went from 20777 to 27004 in the Multi-core test.
