Far Cry 2
I have to admit that the new Radeon HD 69xx graphics cards do not look very convincing against the background of GeForce GTX 570 in Far Cry 2. Nvidia based graphics card is at least as good as the top AMD product when antialiasing is on, and outperforms the top AMD competitor (not to mention Radeon HD 6950) in low image quality modes. Overclocking helps Radeon HD 6950 to change the performance gap to HD 6970 from 7-12% to 1-2%.
BattleForge: Lost Souls
Only in the third gaming test, BattleForge: Lost Souls, the new Radeon HD 6970 and HD 6950 proved to be faster than GeForce GTX 570, but only with antialiasing disabled. As soon as MSAA 4x is activated, Nvidia graphics card regains its lead. Radeon HD 6970 is about 10-11% faster than HD 6950, but this difference, however, is quickly eliminated when HD 6950 is overclocked. The top Cayman is about 25% faster than the top Barts solution.
Resident Evil 5
GeForce GTX 570 is an indisputable leader here. Moreover, the new Radeon HD 69xx cards experience some performance issues in this game when antialiasing is on; they can’t even outperform the Radeon HD 6870.
S.T.A.L.K.E.R.: Call of Pripyat
The new Radeon HD 6970 appears to be the fastest of all today’s testing participants in S.T.A.L.K.E.R.: Call of Pripyat game. The second fastest is GeForce GTX 570, followed by Radeon HD 6950. At the same time I have to point out that the minimal fps rate on an Nvidia based graphics card is higher than on an AMD based one. Radeon HD 6970 is about 13-17% faster than HD 6950, but after overclocking of the latter card, this difference drops down to 3-4%. As for Radeon HD 6870, it falls 35-36% behind the new flagship product from AMD – Radeon HD 6970.
