CrossFire X : gains in 1920x1200

We tested CrossFire X in more detail with different heterogeneous combinations in order to see if performances and the added flexibility was advantageous. We didn’t put these overall results into the "performance recap" graph because this would have made them incomprehensible. Here are the gains from the different solutions. On the one hand, there are those when compared to a Radeon HD 3870 and also when compared to a Radeon HD 3870 X2. In addition to combinations already found on the previous pages, we combined a Radeon HD 3850 256 MB with a Radeon HD 3870 as well as with a Radeon HD 3870 X2. This was also another occasion to look at the difference in gains between two Radeon HD 3870s and a Radeon HD 3870 X2 while keeping in mind that frequencies only differ slightly.

If there are no results, this means that the multi-GPU system had a bug that made the game unplayable. A gain of 0% indicates either that there is no gain or that it reduced performances. In the latter case, it would be deactivated by the user. Therefore there are no negative scores.
