Rememeber that Athlon broke the 1 GHz "barrier" at least 3 weeks before the
Pentium III. Intel decided that this should never, *ever* happen again!

So, the Pentium 4 is *specifically* designed to have a high clock rate. The
Intel engineers got the design parameters:

1. High clock speed
2. High clock speed
3. High clock speed
4. Higher clock speed than *any* brand "A" CPU, anyway!
5. Performance would be nice too, if it doesn't interfere with rules 1-4


And now you say that "sure, the clock speed is high, but some other brands does
more work *per* *clock*".

Duh! Of couse they do. That's by design. Intel was first to 2 GHz. Intel was
first to reach 3 GHz. Intel will certainly be first to 4 GHz. Case closed!

And Intel will maintain that their processors are the Fastest In The World(tm),
because they run at 3.2 GHz!
