Performance

3DMark Vantage

We’ve got an interesting picture in our first semi-synthetic benchmark. The new Radeon HD 7970 GHz Edition is inferior to the GeForce GTX 680 without antialiasing, but the gap shrinks to a minimum at the Extreme settings. When both cards are overclocked, the Nvidia remains a little better than the AMD. Compared to its predecessor, the Radeon HD 7970 GHz Edition is 6.5 to 10.6% faster.

3DMark 2011

The standings are the same in the newer 3DMark, but the GeForce GTX 680 feels more confident here. The Radeon HD 7970 GHz Edition is about 9% faster than the regular HD 7970.

And once again we see the GeForce GTX 680 outperforming both versions of Radeon HD 7970 at the easier settings, but the gap narrows at 1920x1080 with antialiasing. The new Radeon HD 7970 GHz Edition is 10.5 to 12% ahead of the ordinary HD 7970.

S.T.A.L.K.E.R.: Call of Pripyat

AMD’s top-end cards were competitive in this game even before the Radeon HD 7970 GHz Edition, and the latter leaves the GeForce GTX 680 behind by 7.5 to 11%. It must be noted, however, that these two cards are comparable when overclocked, even with enabled antialiasing.

Metro 2033: The Last Refuge

The ordinary Radeon HD 7970 is already a little faster than the GeForce GTX 680 in Metro 2033: The Last Refuge, so the new GHz Edition widens the gap, being 4-6% faster than its cousin. The problem is that Metro 2033 only runs smoothly on these cards at resolutions no higher than 1920x1080.
