Some excerpts taken from the conclusion part [...]
Now that the first review of the 4870 is out, we can compare the two architectures on different fronts.
The RV770 design team should be pretty happy. The GT200 architecture is in no way bad, but in comparison to RV770 and its former mate (G80) it fizzes out. The RV770 architecture looks more scalable [...]
AMD's NDA on the RV770 architecture hasnt lifted yet but we'll bring you the official transistor count of RV770: 965 million. That is a 45% increase over RV770. There were also some rumblings that SP count of 800 is not accurate as it does not include the ones left for redundancy purposes. Keep checking back [...]
RV770 has 800SP
According to the latest reports from Computex, the latest word going around is that RV770 is confirmed to have 800 shader processors. For reference, R600 (2900XT) & RV670 (3850/3870) had 320 shader processors. In total there are 40 TMUs paired to the 800SPs. That is 2.5x the amount of TMUs AMD had stuck [...]
