To keep this 2.9GHz processor cool, this CPU has 95 watts of thermal design power, which is relatively low to keep power usage down. This model differs from the lower cost Phenom II X4 975 model in that the Phenom II X4 975 is a quad core, has only 2MB of L2 cache, runs at 3.6GHz, and has 125 watts of thermal design power. AMD recommends combining the Phenom II X6 1065T Black Edition processor with their 8 series chipset and HD 6000 graphics, for a high quality gaming experience with smooth flow.
