Phenom II X4 965 is a pretty contemporary high-performance processor. With the introduction of 45 nm production process AMD managed to make sure that their processors could finally compete against Intel solutions for LGA775 platform. In nominal mode Phenom II X4 965 performs way better than Core 2 Quad Q9400 with the same price. However, 18% overclocking to 4.0 GHz is not enough for AMD solution to outperform the overclocked LGA775 processor. The thing is that Core 2 Quad has a much better overclocking potential in relative prospective. Even during overclocking to 3.84 GHz limited by the mainboard’s ability to increase the FSB frequency, the clock speed of Core 2 Quad Q9400 processor gets 44% higher. It is more than enough for this processor to look much more convincing than its overclocked Socket AM3 competitor in most cases. As for the LGA1156 platform, the results suggest that it is one of the new generation solutions with a completely different level of performance. Even in the nominal mode Core i5-750 shows results which are just a little lower than the performance of the overclocked Phenom II X4 965. However, once its frequency reaches 4.0 GHz, which is in fact not the maximum this CPU is capable of, the performance of Core i5-750 becomes unattainable for the previous generation CPUs.
