Performance Summary Diagrams

Here is a table with full test results, so we can proceed to our summary charts:

First of all, let’s check out the difference between the pre-overclocked Zotac GeForce GTX 760 AMP! Edition and the reference Nvidia GeForce GTX 760:

Pre-overclocked to 1111/1176/6208 MHz, the Zotac is 3-4% ahead of the Nvidia at 1920x1080 and 6-7% ahead at 2560x1440. The difference is small and far from linear (the Zotac’s GPU and memory clock rates are higher by 13.4% and 3%, respectively).

The following diagrams show the efficiency of the SLI technology as applied to two GeForce GTX 760s:

It’s good that the SLI tandem is always faster than the single card, but the SLI technology has low efficiency in the CPU-dependent modes of Sleeping Dogs and Hitman: Absolution as well as in the new GRID 2. In the majority of the remaining games Nvidia’s multi-GPU technology works very well, with fewer problems concerning the bottom speed. It ensures a performance boost of 64 to 85% at 1920x1080 and 75-82% at 2560x1440.

Now the most interesting comparison is a 2-way GeForce GTX 760 SLI configuration vs. a single GeForce GTX 780:

So, the two graphics cards which cost $100-150 less than the single GeForce GTX 780 beat the latter by 14-19% at 1920x1080 and by 17-18% at 2560x1440. The only exceptions are GRID 2 (where SLI isn’t very efficient) and, to some extent, Company of Heroes 2. Besides, the SLI tandem has a low bottom speed in Sniper Elite V2 and Hitman: Absolution, but overall 2-way SLI based on two GeForce GTX 760s looks a viable solution.
