Nvidia and ATI must be reading our list and decided that they
couldn't
compete with Timothy's efficient "Prius" GPU design, so they are
building the Hummers of GPUs.
Nvidia: 7.1B transistors
ATI: 375 Watts

I wonder how much it costs to run a liquid helium cooling setup?
That's about what it would take to cool these monsters.
I'm even more concerned by 2 things :
* Dark silicon : powering all the gates must be an extreme challenge
* Memory bandwidth wall : the chip can't have enough I/O to feed all
the units with data
(huge amounts of ondie cache are necessary but can't solve
everything)
