Intel Core 2 Extreme: 1333MHz PSB and Beyond

Needless to say, our overclocking experience with the Core 2 Extreme X6800 went very well. The processor effortlessly clocks to 3.33GHz and the P965 works well with a 1333MHz PSB and DDR2-1000 memory, so Intel could have delivered a desktop Extreme processor at those speeds if they wanted to. At 1333MHz PSB, the Core 2 Extreme would have been a real powerhouse compared to the X6800. However, considering the comfortable lead Intel is already enjoying at the moment with the X6800, they’ve probably made a wise decision to stick with the 1066MHz PSB standard for now to keep voltage and temperatures lower.

Looking at all the benchmarks, our overclocked Core 2 Extreme at 3.6GHz makes even the current X6800 look slow. It is clear that the Core 2 scales well with increased CPU frequencies, but provides a better and more linear performance increase through both CPU and FSB overclocking.
