I.e. all four cores working at a speed over 5.2GHz. Ironically he has only performed a SuperPi 1M test at this speed, a test that doesn't even make use of two cores, and the result was mighty impressive; 9.86 seconds. It's the first time Kentsfield goes below 10 seconds with SuperPi 1M and then it's just one of the four cores which is really active. With these results it's pretty easy to understand why Intel has sped up the launch of Kentsfield, it doesn't seem to have any problems with making the four cores work together and at the same time doing so at high frequencies.
