Did it ever occur to anyone that Intel purposefully made the P4 weak per clock cycle so that it could clock much higher overall? It's actually a lot like the RISC philosophy, where chips are supposed to be kept simple. Apple added the SPEC rate results on the G5 performace page as a marketing gimmick. The results in no way mean that a chip is slower or faster than another. The P4 did, after all, beat any Mac and AMD offerings until the G5 and Athlon 64 came out (although its being slower than the G5 is still under dispute).
The Pentium 4
is poorly designed compared to the P3, as well as Apple and AMD's chip offerings. I'm not saying Intel didn't realize this, though. Although it definitely has nothing to do with being "simple". They intentionally threw together a processor that's poorly designed, but capable of higher clock speeds. They did it so they could hammer this whole "clock speeds are everything" concept into PC users' minds.
Of course, clock speed isn't everything. A Pentium 3 could easily beat out a P4 of the same, or even moderately faster, clock speed. Things like cache, RAM, and overall design are actually
more important than clock speed. The P4 simply isn't a well designed processor. It's inefficeint, it gets very hot, they can't even put two of them into one tower without going to a whole lot of work.
Intel took a calculated risk in pushing the P4 over the P3, and it worked at smashing AMD and Apple at first. Now, the P4 is reaching its limit and AMD and Apple are catching up (mostly thanks to IBM on the Apple side). Intel is going to have a hard time moving its desktop systems ahead without doubling back on their "clock speed is everything" message.

And I don't understand where you all got your blind opinions of the G4 and the "multiply it by this to see how fast it is" crap. Motorola's chip division was bought out for a reason. Apple did the smart thing by going back to IBM for the G5. The only problem is, you'll probably never see a G5 in a laptop considering the Power Mac needs 9 fans (granted, they're low speed fans).
Okay. Then I guess the Pentium 4 will never be in a laptop. It's too hot.
What?!
It already is in a laptop?!
Why, that would make your point silly and wrong!
Also, I in no way like the idiots at Moto's microprocessor division. I don't have aa "blind opinion" of the G4, and most people in these forums also don't. We realize the G4 is old, and getting slow. The G5 is better, and we're just at the beginning of a transition over to 64-bit computing, and more importantly, over to IBM processors.
Of course, the G4 is still better designed than the P4.
