SLI technology has higher scalability in Mafia 2 than CrossFireX. As a result, the GeForce GTX 570 pair is as fast as the Radeon HD 6970 tandem and even faster at 1920x1080, although the Radeon wins in single-card mode.
Sid Meier’s Civilization V
Here, the AMD solutions are superior to the Nvidia ones in single-card mode as well as in terms of scalability of multi-GPU technologies.
Like in the previous test, the scalability of the CrossFireX tandem is higher than that of the SLI configuration, so the Radeon HD 6970s gain the upper hand. However, the CrossFireX subsystem is only 75% faster than the single HD 6970. Its bottom speed is high but this must be due to the game engine rather than to the graphics cards or multi-GPU technologies.
Tom Clancy’s H.A.W.X. 2
The Radeon HD 6970 CrossFireX is 83 to 95% faster than the single such card in this game, which is a very good result. On the other hand, the Nvidia solutions are superior to the AMD ones in every test mode and configuration here.
Crysis 2 beta
The beta version of Crysis 2 does not support DirectX 10 and 11 and is also incompatible with multi-GPU technologies. It doesn’t support FSAA, either. So, there is nothing to comment upon except that the Radeon cards have a lower bottom speed than the GeForces. Hopefully, the game will have become far friendlier to CrossFireX and SLI by the time of its release.
