Crysis Warhead & Far Cry 2 Results
The pair of Radeon HD 5870 and HD 4870 X2 cards have been closely matched thus far, with the newer HD 5870 taking a slight lead on higher, more demanding settings; will it maintain or better its performance advantage on real world gaming applications? Read on.
On Crysis Warhead, the pair of Radeon HD 4870 X2 cards was the best performer by far. Managing an incredible 51fps even on the the most demanding setting of 1920 x 1440 with 4x anti-aliasing enabled. But the pair of Radeon HD 5870 cards isn't far behind at all though. The superb performance of the HD 4870 X2 cards is most likely due to the fact that it has a whopping 4GB of frame buffer, as opposed to the HD 5870 cards combined frame buffer of 2GB. To give you some perspective of the matter at hand, a single Radon HD 4870 X2 is slower than a single GeForce GTX 295, so the only logical reason for the CrossFire pair of the 4870 X2 to fair better is more frame buffer in addition to four GPUs to pick up the slack.
On Far Cry 2, the two sets of cards were again closely matched. Despite its larger framebuffer, we noted performance of the pair of Radeon HD 4870 X2 faded gradually as we upped the settings. Remember that the Radeon HD 5870 are running on new drivers, albeit in beta, and it is likely that these new drivers are more optimized for Far Cry 2, thus leading to what we see here.
