Since multithreading is not giving you a major performance boost, Intel came up with Turbo clock. This is what Intel confirmed a day ago when we met in their big and fancy building in Sunnyvale, California.

The Turbo feature will get a clock speed of a CPU clocked eg. To 3.2GHz all the way to 3.5GHz or more and Intel confirmed that they are overclocking any combination of one, two, three or four cores.

Multithreading will certainly help some applications, but some single or dual threaded applications will get a performance boost from Turbo simply as the clock speed of a core will get higher. This works in Nehalem, and naturally it will work with upcoming Lynnfield and Clarkdale / Arrandale Nehalem generation CPUs.
