A Quick Word About Drivers
When this story was originally published in Germany, the newest beta driver version was 301.34, originally intended to add support for GeForce GTX 690. It improves 3DMark results by a few percent, but it wouldn't work with all of our samples. We traced this issue to the BIOS version of some of our test cards, and finally tweaked the .INF file of build 301.33 to get it working with all cards. In that way, the GeForce-based results are all comparable.
Unfortunately, this story went live in Europe long before AMD's beta Catalyst 12.7 build was previewed, and even beta 12.6 was not yet available. As of this writing, the Catalyst 12.7 beta is still not downloadable from AMD's site, so 12.6 is the most current build you can get. Once 12.7 is posted, results for the Radeon HD 7970 should improve, though we saw in AMD Radeon HD 7970 GHz Edition Review: Give Me Back That Crown! that Nvidia's GeForce GTX 670 is faster in 3DMark. Though the Crysis 2 settings used in that more recent story favored Nvidia's card, AMD's Radeon HD 7970 actually wins here.
We ran this benchmark at all three quality presets, and the results demonstrate that performance scales well with clock rate. Although most enthusiasts aren't going to buy a high-end card to play at low-end settings, this metric helps amplify minor differences between the three 1006 MHz samples.
Our tests show that all factory-overclocked cards perform similarly, and they also help illustrate that if a game is unplayable on a board with a 980 MHz core, spending extra on a solution with a 1098 MHz core won't help make it smoother all of the sudden.
Factory-overclocked cards do perform better than reference models at extreme quality settings, but the differences are not earth-shattering.
Crysis 2: DirectX 11
We intentionally selected only one gaming benchmark; adding more wouldn't change the story that plays out between these modified GeForce GTX 670 cards.
It's interesting that the GeForce GTX 680, which is faster in synthetic benchmarks, is equaled or even surpassed by equally-clocked or slightly higher-clocked GTX 670s. This isn't caused by a processor limitation, since we can try different GPU clocks and see immediate frame rate scaling. Rather, we suspect a driver problem. There doesn't seem to be any other explanation.
