Re: power doesn't scale with clock speed.

Yes. power consumption is non-linear with clock, a square law. Higher speeds have been achieved by lower operating voltage and also smaller (related) gate area to reduce capacitance. That's partly why 14nm isn't 14nm in the sense that 90nm is 90nm. Not all aspects have been scaled down.

That's why in the last 15 years number of cores and architecture rather than actual clock is the biggest change.
