Test System Specs & SiSoftware

System specifications for all testing beds are below. You will want to notice that our Core 2 Quad comparison machine is using a Q9650 chip which is the fastest processor currently available in that family bar the Extreme Edition, of course. With the recent CPU price cuts, the Q9650 is available in the ~$320 range which is higher than the Phenom II X4 940 ($235).

First up we have the SiSoftware Sandra 2009 processor arithmetic test, which was used to measure ALU and iSSE3 performance. Given that the Phenom II X4 940 has received a 20% overclock, we are not expecting more than a 20% performance boost; in fact this would be a best case scenario.

The Whetstone iSSE3 test did see a 20% increase in performance when going from 3.0GHz to 3.60GHz.

Then the Dhrystone ALU test saw an unexpected 23% rise in performance which was impressive. These gains put the Phenom II X4 ahead of the Core 2 Quad Q9650 in the processor arithmetic test.
