In CPUs, I think race-to-idle is valid only for lower speeds, such as were common five years ago. Above 1.5 GHz or so, the curve starts bending down and it takes more power to squeeze out each additional MHz (which is why we finally hit a wall and can't make them go faster).
I've noticed the same thing with CPU price. That third GHz costs you more than the second.
