State of 3D

"There are those that joke that the R580 is the die equivalent of a dinner plate. It is a huge die, and with only 36 good ones coming of a wafer with adequate yields, we can see that it is a very expensive die to produce. And this is not even touching the metal layer aspect of production! Apparently the metal layer work on a R580/R520/RV530 is more complex than that of the competing NVIDIA products (much of this complexity is attributed to the Ring Bus memory controller). This means more money per wafer. So with higher costs per wafer combined with ¼ of the good die produced as NVIDIA?s G71, ATI is spending a lot more money for every good die coming off the line. A lot more."


So ATi is spending alot more money per x1900 chip then nvidia is per 7900gtx. I'm guessing everything will change when the dx10 chips come out, we just ned to wait and see.
 
Not only did NVIDIA retain the complete featureset of the GeForce 7 series, but it actually cut down the transistor counts of each of the chips by a pretty significant margin.

^^ Where's the VIVO on the 7900's?
