Good post, Kevin, but I was not trying to say that PII speed advantage comes from higher power dissipation, but that max clock speed (300MHz vs. 233 MHz for K6) comes from higher power dissipation. The backside bus and higher L2 cache frequency of the P2 gives maybe a 10% performance boost, not enough to be worth it by itself, but if you need the thermal brick to handle power dissipation, you might as well put it in.

There are other ways to get high performance without raising clock speed. Cyrix seems to be the best at this since its 6X86mx-PR233 clearly outperforms a P2-233 while running at (I think) 187.5 MHz.
