Performance Summary and Conclusion
Before summing up this test session, we want to show you how efficient the SLI technology is on two GeForce GTX Titan cards:
Adding the second graphics card leads to a performance boost of 90% and higher in the heaviest games at 2560x1400. As a result, you get a playable frame rate in such new titles as Crysis 3, Tomb Raider and Metro: Last Light. Unfortunately for the majority of users who have mundane hardware, only a pair of GeForce GTX Titan cards can ensure comfortable speed in such games at the highest visual quality settings. Subjectively, there are no problems with the 2-way Titan SLI in terms of image tearing or jerkiness. Everything is fast, smooth and beautiful. And, alas, very expansive.
As for the Zotac GeForce GTX Titan AMP! Edition 6GB, the following charts compare its performance against the reference GeForce GTX Titan:
As you can see, the pre-overclocked Zotac is 1.5 to 6% ahead, depending on the specific game, visual quality settings and resolution. That would be nice if this advantage came for free, but the extra speed will actually cost you an additional $150. Moreover, we couldn’t overclock our Zotac more than we had overclocked our reference GeForce GTX Titan from Nvidia. Overclocking depends on luck, though. That’s why we think that the Zotac GeForce GTX Titan AMP! Edition is a good product overall. It is extremely fast. It looks stylish just like any other Titan. It comes with rich accessories. And it is far from affordable. The choice is yours.
