And also remarkably close to the irritating fact that clock speeds seem to have just barely moved over the past 10 years.

A famous Silicon designer once told me "all speed comes from parallelism" & power efficiency as well. Clock speed by itself can be a VERY deceptive measure. Power usage increases linearly with parallelism, but exponentially with clockrate. Speed increases linearly with both.

e^22 = 3.6GHz... which is the t = infinity value. That is not the upper limit. I wonder where that came from.

it isn't the upper limit but we're having a hell of time getting that far past it.

Pretty amazing. Though to split hair, was the formula for "computing power" or "clock speed", because these have diverged quite a bit (ie. long Netburst pipelines of the P4 vs wider modern pipelines with more instructions per cycle, etc).

That’s a rather low Hamming distance :)
