The G80 chip needs a lot of power and is the biggest desktop graphics chip so far. I think the image from toms hardware Italy speaks for itself. here.
Another thing that we learned is that Nvidia uses a new SLI. We saw it here originally spotted at nvnews.net. The new SLI is dual rail stuff. It is ironic that ATI was the first to introduce such a connector that will let you have read and writes performed at the same time.
As for the rest, no one yet knows how many real pipelines this card has but you can rely on the 1.5GHz scalable clock rates. This doesn't mean much to us as in theory this card is super fast but we will be anxious to see it in action.
G80, Geforce 8800 GTX and GTS are two biggest graphic cards ever and here is the link for the retail Asus card. Samples should be distributed this week and some lucky chaps got the cards back at Nvidia's editor's dates. ยต
