Overclocking the Phenom II X6 1090T from 3.20GHz to 4.02GHz greatly improved performance when testing with Microsoft Excel and allowed the 1090T to deliver similar performance to the Core i7 930 processor. While this is not a great accomplishment in itself as the Core i7 930 is operating at its default frequency of 2.66GHz it is nonetheless a sizable performance increase.
Decent performance gains were also seen when testing with Far Cry 2, though the boost was not enough to help the Phenom II X6 1090T overtake the Core i5 750 processor in this game.
HandBrake was one of the best applications that fully utilized all six-cores and when overclocking the Phenom II X6 1090T all the way to 4.02GHz we saw tremendous performance gains. Not only was performance boosted by 22%, but the 1090T was almost on par with the more expensive Core i7 980 XE that also has twice as many threads at its disposal.
