Performance recapAlthough individual game results are obviously worth looking at when you want to gauge performance in a specific game, we have also calculated a performance index based on all tests with the same weight for each game. We set an index of 100 to the GeForce GTX 680 in SLI:
[ 1920x1080 ] [ 2560x1600 ] [ 5760x1080 ]
On average, the GeForce GTX 690 finishes 3% behind the GeForce GTX 680 SLI at 2560x1600 and 2% behind at 1920x1080. This is an excellent result for a bi-GPU card. The average performance of the Radeon HD 7970s in CrossFire X is similar.
Note that the positions of the GeForce GTX 680 and the Radeon HD 7970 have been reversed compared to the results in our initial test of the GeForce GTX 680. There are several reasons for this:
- Here we used a GeForce GTX 680 from a store which had a maximum clock of 1084 MHz as against 1110 MHz on the press sample.
- AMD has finally (after 5 months!) corrected a performance problem in Batman AC with MSAA.
- Nvidia cards suffer from a performance problem in the latest version of Total War Shogun 2.
- The 1920x1080 index includes only extreme quality benches because of our ultra high end focus here and the GeForce GTX 680 fades a bit at extreme quality.
