NVIDIA GeForce GTX 770 2GB Video Card Overclocked - Benchmarks - Test System Setup

By: Shawn Baker | NVIDIA GeForce GPU in Video Cards | Posted: Jun 12, 2013 7:30 am



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


You'll see an almost identical line up of video cards that you saw in our original GTX 770 2GB review today. On the NVIDIA side we've got the GTX 770 2GB clocked at its reference speeds along with the GTX 650 Ti Boost reference cards in SLI. We also have the reference clocked GTX 780 and the pre-overclocked GTX TITAN 6GB SC from EVGA.


On the AMD side we've got the PCS HD 7950 from PowerColor which we've overclocked to over 1100MHz on the core, alongside the reference clocked HD 7970 GHz Edition.




Looking above you can see we pushed the core up to 1153MHz or 1192MHz via boost. This is a nice increase from the stock 1046MHz or 1085MHz via boost clock. As for the memory, the 2GB of GDDR5 already came in at a very strong 7012MHz QDR, but you can see we managed to push it to 7664MHz QDR, which is a really high memory clock speed.



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.
