We've already seen the new GHz Edition Radeon HD 7970 at stock speeds. Now let's see how it goes when it comes to overclocking.

We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS and Corsair.

 

Having a look at the testbed you can see nothing has changed and everything is fairly self-explanatory in the above image. So with that said let's quickly look at the video cards that sit in our graphs today.

 

Of course we've got our overclocked HD 7970 GHz Edition card and we'll be looking at that against the original HD 7970 and the GHz Edition model when it's running at its stock speeds.

 

Along with those cards, though, we've got the GTX 670 and three GTX 680s in the form of a 2GB and 4GB one running at stock and a pre-overclocked 2GB model from Gainward in the form of the Phantom. All these cards are important today when it comes to being compared against each other.

 

We saw the HD 7970 GHz Edition perform strong in our testing the other day, but it continued to struggle at times against both the GTX 680 and GTX 670. Let's find out what the extra clocks do for the card today.

 

Let's get started!

 

 

The FPS Numbers Explained

 

When we benchmark our video cards and look at the graphs, we aim to get to a certain level of FPS which we consider playable. While many may argue that the human eye can't see over 24 FPS or 30 FPS, any true gamer will tell you that as we climb higher in Frames Per Seconds (FPS), the overall gameplay feels smoother. There are three numbers we're looking out for when it comes to our benchmarks.

 

30 FPS - It's the minimum number we aim for when it comes to games. If you're not dropping below 30 FPS during games, you're going to have a nice and smooth gaming experience. The ideal situation is that even in a heavy fire fight, the minimum stays above 30 FPS making sure that you can continue to aim easily or turn the corner with no dramas.

 

60 FPS - It's the average we look for when we don't have a minimum coming at us. If we're getting an average of 60 FPS, we should have a minimum of 30 FPS or better and as mentioned above, it means we've got some smooth game play happening.

 

120 FPS - The new number that we've been hunting down over recent months. If you're the owner of a 120 Hz monitor, to get the most out of it you want to get around the 120 FPS mark. Moving from 60 FPS / 60 Hz to 120 FPS / 120 Hz brings with it a certain fluidity that can't really be explained, but instead has to be experienced. Of course, if you're buying a 120 Hz monitor to take advantage of 3D, an average of 120 FPS in our benchmark means that in 3D you will have an average of 60 FPS, which again means you should expect some smooth gameplay.
