The iPhone 3G and 3GS have 150K pixels but the 4G is 600K and the iPad is
800K - more than a 1/3 of 1080p - and it's not use 33W either. But that was
just a convenient example - there are any number of hardware decoder chips
available (use Google), and none of them require 10W let alone 100W.

Bingo. Like I said, nVidia cards require 100W to do their 3D processing, not
to decode h.264.
