Gud lorde, don't be daft. PPW matters until it hits a point where any optimizations above that line are of much less importance to some people (e. g. me) than other specs. Not to speak of necessary attributes completely absent from your PPW dream machine, which indeed negates PPW considerations on a per device/device-class basis. Which excludes optimizations for microprocessor series. It ain't rocket science.
