I've always been a HUGE fan of the PowerVR tech (the GPU inside the iPhone/iPad), even going so far as buying shares in the company when I was a kid (I was an odd kid).

From what I understand of the technology it was built with efficiency from the ground up as opposed to the nVidia tech of the time such as the TNT and Geforce which were designed for raw performance.

Good article about it: http://www.anandtech.com/show/558/4

I think Videologic/Imagination Tech patented the heck outta a lot of the techniques they came up with so wouldn't be surprised if they're ahead of the pack on efficiency.
