Nvidia introduced a lot of new video cards in a pretty short amount of time over the past few months. First the new flagship arrived, the GeForce GTX Titan. Then came the 700 series, one new card after another in short succession: the GeForce GTX 780, GeForce GTX 770 en GeForce GTX 760. Today we'll be discussing the performance of SLI and 3-way SLI of the Nvidia GeForce GTX 700 series.
We tested the following configurations:
- Nvidia GeForce GTX 760
- Nvidia GeForce GTX 760 SLI
- Nvidia GeForce GTX 760 3-way SLI
- Nvidia GeForce GTX 770
- Nvidia GeForce GTX 770 SLI
- Nvidia GeForce GTX 770 3-way SLI
- Nvidia GeForce GTX 780
- Nvidia GeForce GTX 780 SLI
- Nvidia GeForce GTX 780 3-way SLI
We tested the GeForce GTX 760 with GeForce driver version 320.39, and the 770 and 780 with 320.18. The performance difference between the two driver versions is negligible.
We used our standard graphics card testing system, consisting of an Intel Core i7 3960X (Sandy Bridge-E) processor, an ASUS P7X79 Pro motherboard, 16GB Corsair DDR3-1600 memory, a Samsung Spinpoint F1 hard drive, and a Cooler Master Silent Pro Gold 1200 watt power supply. All benchmarks were done in Windows 7 x64.
We ran the benchmarks in two resolutions: 1920x1080 (Full HD) and 5760x1080 (3x Full HD). Three monitors mean 6.2 million pixels, Full HD is slightly over 2 million, 2560x1440 is 3.7 millon pixels and 2560x1600 is 4 million pixels.
Frametimes test: In a few of the benchmarks we also looked at the render times of individual frames, and based on this data calculated what the 99th percentile value is. You can read more about what the frametimes test entails here.
Anyone who's tried multiple video card configurations will know that two or more cards will work great in some games, and real poor or not at all in others. This explains the sometimes odd results in the charts. This is especially true for the frametime results, which you can read more about here. SLI/Crossfire and Fraps can lead to strange scores.
We don't have AMD CrossFireX scores this time. In the near future we will have a review for you with all Crossfire combinations of the Radeon HD 7950 Boost and Radeon HD 7970 GHz Edition cards.
