Yep I get 4.35x if I extrapolate the numbers from GK107-GK110 to GM107-GM200 (Assuming the same 551 mm2 die).Numbers: GK107 - 11.02 million/mm2, GK110 - 12.89 million/mm2, i.e. a increase of 16.9%. GM107 is 12.63 million/mm2 so scaling by 16.9%, GM200 would be 14.78 million/mm2. At 551 mm2, it comes up to about 8.14B transistors.Regarding performance, assuming that GM107 performs 78% better than GK107 (source:Techpowerup - http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_750_Ti/25.html ), I get roughly 40% higher performance for GM200 over GK110.I know scaling is not always linear but in the case of GK107 to GK110 it seems to be extremely linear. From the same review, GK110's performance is 4.66 times that of GK107..and we know that the die size is 4.67 times that of GK107. Very simplistic analysis I know..but gives us a ballpark.
