I'm not going to get into why we're bring you an overclocked article on the unreleased GTX 670 because I think we've done a pretty good job of making it clear. If you do want to know more about it all, though, I recommend you look at our GEFORCE GTX 680 review and our GEFORCE GTX 670 preview along with our news post on why we didn't get a GTX 690.

As for what we're doing here today, as we just mentioned we'll be overclocking the soon to be released GTX 670. This is a video card that really impressed us with some amazing performance when we tested it on the weekend. We wonder what kind of overclock we're able to get out of it.

Talking to some partners, word is it's not the best when it comes to overclocking, but apparently they have no issue reaching the same speeds as the GTX 680, but beyond that there's not a lot of headroom. We'll find out just what we're able to get out of the video card today, though.

There's not a lot to do here today. Like our original coverage on the GTX 670 we won't be including any pictures, instead we'll quickly get into the testbed side of things. Once we've done that we'll quickly cover the overclocking and then we'll get straight into the performance, which is what you came to see.

Benchmarks - Test System Setup and Specifications

NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 99 | TweakTown.com

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

Looking at the testbed there's nothing out of the ordinary with the same X79 testbed being used. Before we get into the testing side of things, though, we want to take a look at how we went with overclocking via the help of MSI Afterburner.

Having a look below we can see the exact kind of overclock we managed to achieve out of the video card. Starting with the core you can see we managed to push that up from the stock 915MHz / 994MHz via turbo to 1061MHz / 1140MHz. This isn't a bad overclock at all and should bring with it a decent boost in performance.

NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 01 | TweakTown.com

Of course the other thing we overclocked was the 2GB of GDDR5 that is present. Looking above you can see we pushed that from 6008MHz QDR to 6460MHz QDR. This isn't a huge overclock, but combined with the bump in core clock, we should see a nice boost in overall performance that may put the model ahead of the GTX 680 at stock.

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.

Lost Planet 2 is a third-person shooter video game developed and published by Capcom. The game is the sequel to Lost Planet: Extreme Condition which is also made by Capcom, taking place ten years after the events of the first game, on the same fictional planet. The story takes place back on E.D.N. III 10 years after the events of the first game. The snow has melted to reveal jungles and more tropical areas that have taken the place of more frozen regions. The plot begins with Mercenaries fighting against Jungle Pirates. After destroying a mine, the Mercenaries continue on to evacuate the area, in which a Category-G Akrid appears and attacks them. After being rescued, they find out their evacuation point (Where the Category-G appeared) was a set-up and no pick up team awaited them. The last words imply possible DLC additions to the game, "There's nothing to be gained by wiping out snow pirates... unless you had some kind of grudge."

Checking out Lost Planet 2 performance we continue to see a nice boost in performance that gives us a bit more breathing room at 2560 x 1600.

Compared to the other video cards here, you can see we're sitting close to the reference GTX 680 and of course have no issue dealing with the AMD HD 7900 series offerings.

Benchmarks - Aliens vs. Predator

Aliens vs. Predator is a science fiction first-person shooter video game, developed by Rebellion Developments, the team behind the 1999 original PC game, and published by Sega for Microsoft Windows, the PlayStation 3 and the Xbox 360. The game is based on the Alien vs. Predator franchise, a combination of the characters and creatures of the Alien franchise and the Predator franchise. There are three campaigns in the game, one for each race/faction (the Predators, the Aliens and the Colonial Marines), that, while separate in terms of individual plot and gameplay, form one overarching storyline.

Following the storyline of the campaign modes comes the multiplayer aspect of the game. In this Multiplayer section of the game, players face off in various different gametypes in various different ways.

NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 25 | TweakTown.com

Looking at Aliens vs. Predator performance we can see some excellent gains again. The most important gain comes at 2560 x 1600 where we see the overclock helps us break into that 60 FPS average that we try so hard to reach for a solid gaming experience.

It's exactly at these times where overclocking becomes extremely useful.

Benchmarks - Just Cause 2

Metro 2033 sees some strong performance gains, but like Aliens vs. Predator, this is an important one where we see the overclock helps boost our average to that 60 FPS mark, which we always aim for to provide solid gameplay performance.

Benchmarks - Dirt 3

NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 29 | TweakTown.com

Moving along to Far Cry 2 we don't get any real surprises with strong performance across the board. We see a nice boost in performance at all resolutions, but for the most part it's not really needed.

Benchmarks - High Quality AA and AF

High Quality AA and AF

While we test all our games with maximum in-game settings, turning on Anti-Aliasing (AA) and Antistrophic Filtering (AF) helps take the intensity of our testing to another level.

Here we see video cards go from playable FPS to an unplayable FPS and the real power houses continue to help break that 60 FPS mark we always aim for to provide a smooth gaming experience.

NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 30 | TweakTown.com
NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 31 | TweakTown.com
NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 32 | TweakTown.com

Turning on AA and AF we can see some nice gains at all resolutions. Aliens vs. Predator is the most important, though, and while we do see a really nice boost, we're just a few FPS away from that magical 60 FPS mark we aim for.

Far Cry 2 and Mafia II sees some great performance, though, with very playable numbers.

Power Consumption Test

Using our PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly known as to our readers, we are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into AC wall socket).

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

The other thing to remember is that our test system is bare minimum - only a SSD hard drive is used with a single CD ROM and minimal cooling fans.

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

NVIDIA GEFORCE GTX 670 2GB Video Card Overclocked Performance Preview 42 | TweakTown.com

Checking out power draw we can see that the idle draw comes in a little above 200 watts, while the load number sits at just over 400 watts.

Here we see some pretty standard numbers that tell us most quality and branded power supplies won't have issues dealing with this kind of setup.

Final Thoughts

NVIDIA GEFORCE GTX 670 overclocking numbers aren't as impressive as we'd hoped and talking to a couple of partners about these OC results, the numbers seem consistent. What we tend to be hearing is that while getting to GTX 680 speeds aren't a problem, moving much higher is a little bit of an issue.

Of course clocking the video card at GTX 680 speeds doesn't mean we'll get GTX 680 performance due to the reduced CUDA core count on the GTX 670. The slightly higher clocks over the 680 help close the gap, though, and most of the time sees the GTX 670 come out ahead.

As we see companies offer us new coolers and different PCBs over the coming weeks, we might see higher overclocks, but the general word from companies is that the GTX 670 just isn't a massive overclocking video card. To be honest this doesn't surprise us all that much as the GTX 680 doesn't seem to be the biggest overclocking part either.

There's not much else that really needs to be said for the most part. The GTX 670 continues to be a great performing video card, but like the GTX 680, overclocking isn't it strongest area. Considering that most people are going to see stock performance or pre-overclocked performance, this model is going to continue to be a headache for AMD.

Keep an eye out on May 10th when the model officially gets released by NVIDIA and we bring you a look at a non-reference video card that will hopefully impress us like the reference design video card we've looked at here today.
