Performance

The results of the 2-way SLI configuration (built out of two GeForce GTX 780 Ti cards) and of both dual-GPU cards from Nvidia are indicated in turquoise. The single-GPU GeForce GTX cards are green and the AMD-based cards are red.

Considering the high performance and price ($1500 and more) of the GeForce GTX 780 Ti tandem, we’re going to focus on the resource-consuming mode (2560x1440 with different types of antialiasing). We guess no one would build such an advanced graphics subsystem to play at a resolution lower than 2560x1440 and without AA. Still, the diagrams show all of our test results.

3DMark (2013)

The GeForce GTX 780 Ti SLI tandem is up to 70% efficient at the highest settings, outperforming its closest opponent, the dual-processor Nvidia GeForce GTX 690, by 51%. So we seem to have built a very fast SLI configuration...

Unigine Valley Bench

The GeForce GTX 780 Ti is the same 75% faster than the single such card in Unigine Valley as well. The difference from the GeForce GTX 690 is smaller than in 3DMark (2012) at 42%.

Total War: SHOGUN 2 – Fall of the Samurai

This game’s engine runs smoothly on multi-GPU configurations, both Nvidia SLI and AMD CrossFireX. Here’s yet another proof:

Although the game is nearly 3 years old, it is still a heavy load even for top-end graphics solutions at 2560x1440 with maximum visual quality settings. The two GeForce GTX 780 Ti in SLI mode show their best here, beating the single GTX 780 Ti by 86% and the dual-processor GTX 690 by 48%!

Sniper Elite V2 Benchmark

The 2-way SLI tandem built out of GeForce GTX 780 Ti cards is impressive in this game, too:

The two GTX 780 Ti cards are 85% faster than the single GTX 780 Ti and 45% faster than the second-best GTX 690. The bottom speed is rather low with each of the tested graphics solutions, though.

Sleeping Dogs

Top-end graphics solutions can only show their full power in the most resource-consuming test mode here.

At 2560x1440 with high-level antialiasing the two GeForce GTX 780 Ti cards are as much as 82% ahead of the single GTX 780 Ti and also beat the Nvidia GeForce GTX 690 (by 47%) and AMD Radeon HD 7990 (by 78%).

Hitman: Absolution

Although a CPU-dependent game, Hitman: Absolution benefits from enabling SLI on our two top-end graphics cards:

The two GK110-based cards are up to 79% faster than the single such card here. As opposed to the previous tests, the AMD Radeon HD 7990 is second, outpacing the GeForce GTX 690. It is still 47% slower than the leader, though.
