First, let’s see the difference between the GeForce GTX 650 Ti Boost and the GeForce GTX 680:
The GTX 650 Ti Boost is an average 34-37% slower at 1920x1080 and 38-39% slower at 2560x1440. We should remind you that the GTX 650 Ti Boost is slightly pre-overclocked while the GeForce GTX 680 works at its default settings.
Next let’s check out the efficiency of SLI technology as applied to two GeForce GTX 650 Ti Boost cards:
The SLI tandem is an average 70-86% ahead of the single GTX 650 Ti Boost at 1920x1080 and 82-84% ahead at 2560x1440. So the GTX 650 Ti Boost SLI configuration can beat a single GeForce GTX 680 almost everywhere:
The only exception is Hitman: Absolution without antialiasing and one result in Sleeping Dogs. Overall, the 2-way GeForce GTX 650 Ti Boost SLI configuration is 12-17% faster than the single GeForce GTX 680 at 1920x1080 and 12-14% faster at 2560x1440. And the two GTX 650 Ti Boost cards cost less than one GTX 680!
