Intel took nearly 29 years to produce its first 1-GHz processor, but
just 18 months more to push its Pentium 4 to the 2-GHz mark,
further increasing the P4's speed advantage (on paper) over
AMD's current crown jewel, the 1.4-GHz Athlon.
But our tests show that despite the new chip's extra megahertz, the
Athlon still performs better on some applications."
