Heat sinks have been huge since the G5 was introduced. Even the later G4s had massive heat sinks. Both generations of machines had substantial cooling systems and multiple fans. In the later G4s, this was an issue, as the fans generated lots of noise. It was solved in the G5s by creating multiple thermal zones, with a total of 5 fans throughout, all controlled and coordinated by the machine to maximize efficiency and reduce noise.

When the G4 Powerbook was introduced, Apple went to 70 watt power adapters, due to the machine needing to pull more power than previous models.

There was a time when the PowerPC was much more efficient than comparable Wintel models, but that hasn't been for a few years, and it hasn't been a marketing point in some time.

It's kind of unfair to cite marketing from many years and 1.5 major chip revs ago as conflicting with the company's planned course of direction two years from now.
