My Intel Pentium 4 3.0Ghz processor with HyperThreading seems in every way to me as fast as a 3.0Ghz processor would be expected to be, even when my task manager shows 50% CPU being used. Because the maximum of the "total" CPU a single-thread app can use is 50%, I would think that if my computer has the equivelant of two 1.5Ghz processors, I would notice my computer being slower than my old 1.7 GHz PC which ran video processing and other intensive tasks VERY SLOW. But that is not the case. A single thread app (which therefore only shows up as using 50% CPU) runs extremely fast on my computer, and I am quite happy with the speeds I am getting. Now this isn't proof that a HT processor does not have 2x times 1/2 the CPU rating, but as far as I'm concerned, it runs just as well as two 3.0 GHz processors. Even then, I'm not sure Intel would be allowed to quote their processors at 3.0 Ghz when the core clock is really running at 1.5 Ghz.
