Yes, 55nm really works for ATI. 576mm2 is to large, especially when a RV770 is twice as small.Originally Posted by largon
Again, that all boils down to incompetence. No matter how you look at it.
And besides, 55nm is now just as mature as 65nm was when G92 came out.
Err... what?
55nm is the issue here. 55nm works for ATi, and assuming the bunnies at TSMC are not ATi-fans then the root of the problem is at nV.
RV770 = between 830 and 1300 million transistors = 256mm2
GT200 = 1000 million transistors =576mm2
If you look it like this they really should have used 55nm die shrink instead of 65nm. GT206 will be 55nm.
R600 had 30% transistors then G80 but G80 owned R600. ATI RV770 has to be really efficient to keep up with nVidia.
It looks to me nVidia might have a killer card, although I'm not sure about the heat dump. I hate stupid heatspreaders on GFX cards.
