AMD RV790 & RV740 in 40nm in March 2009

[LordEC911]

On 40 nm, i think ATi can easily hit around 1600 SP 80 TMU 24 ROP specced chip with die size budget beetween 260-300 mm^2, if they can keep their success in designing a pretty dense transistorwise GPU chip.

Your specs are too low or your diesize is way too large.
40nm's main advantage is that increased density. AMD/ATi already did a great job with RV670/RV770 density and I'm sure they will do it again.

R600@80nm. is 408 mm^2
RV670@55nm. is 192 mm^2
And they are pretty much the same chip, they added some features and cut the memory controller in half, but the amount of transistors is roughly the same.

R600 was ~420mm2 with 720m.
RV670 had UVD ondie, DX10.1 logic, power controllers.
