Sniper Elite V2 Benchmark
The 2-way GeForce GTX 770 SLI configuration enjoys its largest advantage over the GeForce GTX 690 in this test session: 17 to 26%. On the other hand, we don't see such a large difference in terms of bottom speeds. The bottom speed of the SLI tandem is only comparable to that of the single-processor GeForce GTX 770 cards.
Sleeping Dogs is a CPU-dependent application too, so we can only evaluate the efficiency of the SLI tandem when we turn on antialiasing. In that case, the two GeForce GTX 770s are 87 to 97% ahead of the single GTX 770 and faster than the GeForce GTX 690.
The Hitman: Absolution benchmark seems to be even more limited by the overall performance of the platform, so every graphics card produces the same result at 1920x1080 without antialiasing.
But when we turn on 8x MSAA, we can see the second GeForce GTX 770 add 74-81% to the speed of the first one in the SLI tandem, so the latter is slightly ahead of the overclocked GeForce GTX 690.
Crysis 3 is yet another game where 2-way SLI works perfectly. The SLI tandem is 86 to 90% ahead of the single card, has no problems with bottom speed, and easily beats the more expensive dual-processor GeForce GTX 690.
Tomb Raider (2013)
In the new Tomb Raider the 2-way SLI tandem boasts its highest efficiency in this test session – up to 100%! Considering that the bottom speed grows up, too, the two GeForce GTX 770s show exemplary performance here. They also have a clear advantage over the GeForce GTX 690 in this game.
