Tech Radar has had the chance d' to have a prototype in hand of a Xeon mother board equipped with two Nehalem processors running at 2,8 GHz. The machine was equipped in addition with 24 GB of 1066 MHz RAM DDR3.
They could not make and publish large tests, however they launched SPEC CPU2006, a test often used by the foundries to give the raw power of their processor.
The machine obtained a score of 160. This figure does not mean much by itself, however we know that a configuration similar to our Mac Pro and equipped with two 3,4 GHz Xeon obtained 90 points with this test.
Thus the difference is enormous, and one could deduce from this simple test that the next Mac Pro has a high risk of blowing away the current model.
Note that this result is due mainly to the memory bandwidth (with the controller integrated int
