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

 

We've got a number of video cards in our graphs today, but the main one we're going to be looking at is of course the performance of this 2GB model against the 1GB version.

 

The clock speeds of the two cards do have to be noted, though. The 2GB card as we mentioned comes in with a 1050MHz core and a 6400MHz QDR memory clock. The 1GB version on the other hand comes with a slightly elevated 1075MHz core - the memory is clocked the same at 6400MHz QDR.

 

A 25MHz difference in core clock is going to make very little difference to performance. It's of course something that we have to clearly mention - if the extra memory is going to really help, though, the extra 25MHz on the core will be negated easily.

 

Alongside these two others included are the HIS HD 7750 IceQ X Turbo, HIS HD 7770 iCooler overclocked to over 1100MHz on the core, along with a couple of NVIDIA cards including the reference GTX 650 Ti 2GB Boost, the pre-overclocked Palit GTX 650 Ti Boost and the MSI GTX 660 Hawk 2GB.

 

 

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.

 

Why are some graphs incomplete?

 

Adding new game benchmarks is a long, tedious and time consuming task as every video card has to be re-tested in those new benchmarks. Because of that reason we have always just evaluated our benchmark line up every six months. To stay up to date and current with the latest benchmarks and games available, we've changed our approach to adding new benchmarks.

 

Our benchmark line up will progress and be updated as newer more intensive games with benchmarks comes to light. While this will mean that initially you may only see a single video card in those particular graphs, as the weeks go on and we test more and more video cards, the results will grow quickly. This will help keep our benchmark line up as up to date as possible as we introduce and remove games on a constant basis.
