The numbers from semi-synthetic benchmarks and Aliens vs. Predator (2010) will be illustrated by screenshots with the results of the Zotac GeForce GTX 680 AMP! Edition at its default (left) and overclocked (right) frequencies.
The default Zotac GeForce GTX 680 AMP! Edition is 6% ahead of the reference GeForce GTX 680 without antialiasing and 9% ahead when antialiasing is turned on. It also outperforms its junior cousin Zotac GeForce GTX 670 AMP! Edition by a similar margin. The Radeon HD 7970 GHz Edition is much slower at the Performance settings but closes the gap at the Extreme settings thanks to its larger amount of onboard memory and wider memory bus.
The Zotac GeForce GTX 680 AMP! Edition is ahead in 3DMark 2012 both at its default and overclocked frequencies. It has no rivals today, actually, and enjoys an advantage of 8-9% over the reference GeForce GTX 680.
