As opposed to many of the previous games, the Titan SLI tandem is really useful for Crysis 3 as it makes the resolution of 2560x1440 pixels playable at the highest visual quality settings. The SLI efficiency is high ranging from 75 to 93%. The Zotac version is 2-6% ahead of the reference Titan from Nvidia.
Tomb Raider (2013)
The 2-way Titan SLI tandem looks perfect in Tomb Raider:
The SLI efficiency is 92% and higher here, and the double speed is most appropriate in this very resource-consuming game.
The Titan pair isn’t that efficient here and has problems with the bottom speed.
The two GeForce GTX Titans are 66-77% faster than the single one. That’s not much but the game is new, so we can expect it to improve in terms of SLI compatibility through future patches and driver updates.
Metro: Last Light
The SLI efficiency is not very high in this game, but the performance of the 2-way Titan SLI configuration is impressive, especially in comparison with the fastest single-GPU card of Nvidia’s previous GPU generation.
Here’s a table with full test results:
