Hmm, no I don't. =) I do know that an O(log n) multiplication routine is better
than an O(n) one, but I don't count clock cycles. I'm sure some programmers do,
though.

There's money involved in that. Intel pays major (and minor?) software companies
to make their games slow, and include unnecessary delay routines into them. This
way, people figure they need a faster processor, and so they buy one from Intel.

It is also worth noting that Intel probably know how to make faster processors
than they're currently selling. (This is just speculative, mind you.) The guy
who gave us Moore's Law (computing power doubles every 18 months) was the
founder of Intel, and naturally they try to stick to his prophecy as exactly as
possible.
