Recap
Although individual game results are interesting, we calculated a performance index based on all tests with the same weight for each game. A score of 100 was given to the GeForce 8800 GTS 512 MB in 1920x1200.
On average the GeForce 9800 GX2 turns out to be 45% better than the GeForce 8800 Ultra and 18% above the Radeon HD 3870 X2 which it dethrones.
With 4x antialiasing filtering activated, bugged ROPs in antialiasing with the Radeon HD 2000 and 3000 forced AMD to find an alternative solution that while it is very flexible limits performances. For this reason, the GeForce is better positioned compared to AMD’s offer. The advantage of the 9800 GX2 over the Radeon HD 3870 X2, for example, climbs to 35%.
Note that results obtained in Rainbow Six : Vegas and Bioshock are not taken into account here because some cards aren’t capable of supporting antialiasing in these games. Otherwise, you can consult a graph that includes this information in the final grade
here.
In DirectX 10 we find similar rankings. The activation of anti-aliasing is in the favor of GeForce cards or at least those equipped with 768 MB of memory. In this area, the GeForce 9800 GX2 displayed inconsistent behavior from one game to another due to its memory limited to 512 MB.
Note that the results obtained in Bioshock were not taken into account here because the Radeons are not capable of antialiasing in this game in DirectX 10 mode. You can consult a graph that integrates this information
