Phenom II X2 vs. Athlon II X2 - A Question of Cache

Test Setup

Test Setup

To level the clock speeds between the Athlon II X2 and Phenom II X2, we tested an Athlon II X2 250 (3.0GHz) with an Phenom II X2 555 BE (underclocked to 3.0GHz from 3.2GHz). These two processors are then tested in various CPU and gaming benchmarks. We have also included results from the quad-core Athlon II X4 630 and 620 as reference points for those who are more inclined to go quad-core due to their usage.
