We're a little later then we had hoped this time bringing you our look at the upcoming GEFORCE GTX 660. While we actually received our first retail sample about a week ago it wasn't till a week later that we managed to score a reference card from a company that gave us the ability to bring you an early look at the new GTX 660 that NVIDIA is set to launch in just over a week.

We're being super cautious this time as NVIDIA seemed to work really hard to figure out where our GTX 660 Ti sample came from originally to the point where they seemed to just blame everyone hoping that one company would eventually crack. Because of that we're not going to be including a GPU-Z screenshot or anything like that. We will cover the main specifications of the card, though. It's fairly safe to say, though, that our track record speaks for itself when it comes to having the latest NVIDIA cards prior to the official release date.

The GTX 660 marks almost the end of the 600 series that we're interested in with only one more model due in the form of the GTX 650. There's no denying that the GTX 660 is going to be one of the more important models for NVIDIA and consumers, though, as it hits in at that mid $200 price bracket, one of the most popular price points when it comes to quantity. What kind of performance does a mid-$200 NVIDIA based video card bring to the table this time around, though? Well there's ultimately only one way to find out and that is to benchmark it.

There's really not much more that we need to talk about. We'll quickly cover the main specifications and once we've done that we'll move onto test system side of things and cover the cards that we'll be using in our graphs today before we finally get into the performance side of things.

Specifications

Out of the box a reference clocked GTX 660 is going to come in with a 980MHz core which via boost gets pushed up to 1033MHz. A lot like the GTX 660 Ti, though, we should see companies offer overclocked variants of the model quite quickly. Some of the other main specifications include 960 CUDA cores which compares to the 1344 present on the GTX 660 Ti.

On the memory side of things we've got 2GB of GDDR5 on a 192-bit memory bus which is the same as the GTX 660 Ti. As far as clocks go we've also got the same 6008MHz QDR present. The big difference between the GTX 660 and the more expensive Ti, though, is the CUDA cores.

How much difference, though, we'll find out in just a moment. For now let's quickly see what's going on with our testbed and the cards that we'll be including in our graphs today.

Benchmarks - Test System Setup

Outside of the reference GTX 660 that we have here today two of the main video cards from the NVIDIA side of things we'll be comparing it against is last generations single GPU king, the GTX 580. Along with that, though, we also want to see what kind of difference the Ti adds.

Of course we've also got the GTX 670 and GTX 680 for good measure as well. On the AMD side of things we've got the typical top to bottom line up starting with the HD 7870 which is going to be the main competition for the GTX 660 as it falls in at that mid-$200 price range as well.

Above that we've also got the HD 7950 and HD 7970 along with the new GHz Edition of the HD 7970 to round off everything.

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.

Benchmarks - 3DMark 11

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 20 | TweakTown.com

Starting off with 3DMark 11 we can see that performance between the new GTX 660 and the older GTX 580 is near identical.

Against the AMD side of things you can see we're sitting around HD 7950 level performance. Of course 3DMark 11 isn't always the best to gauge a whole model off, but it helps create a good benchmark of what we're expecting to see.

Let's see if we continue to sit around GTX 580 numbers as we continue on with our benchmarks.

Benchmarks - Unigine Heaven Benchmark

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 21 | TweakTown.com

Looking at Heaven numbers we can see that performance is looking good again for the GTX 660 with a decent gain over the older GTX 580 and strong numbers compared to the HD 7870.

Tessellation has always been a strong point for NVIDIA, though, so let's see what happens when we continue on with the benchmark line up here today.

Benchmarks - Tom Clancy's H.A.W.X. 2

While not quite GTX 580 numbers here we've got extremely playable numbers across the board. Compared to the AMD side of things you can see we're very close to the HD 7870 in this case with little separating both at all resolutions.

Benchmarks - Mafia II

There are around 50 vehicles in the game, as well as licensed music from the era.

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 23 | TweakTown.com

Moving into Mafia II we've got a few important things here. The first is that we're again sitting around GTX 580 performance across the board. The second is that we manage to break that 60 FPS barrier at 2560 x 1600.

The third is compared to the AMD side of things you can see we're ahead of the HD 7870 at the lower resolutions, but fall a little behind when we get to the highest. Again, though, the most important thing is that we're able to break that 60 FPS number at the highest resolution for what we consider to provide a smooth gaming experience.

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."

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 24 | TweakTown.com

Looking at Lost Planet 2 we can see we don't quite get the numbers we need at 2560 x 1600, but below that, the numbers look good.

Compared to the GTX 580 you can see we're ahead as we climb the resolution table. Against the HD 7870 we can also see that performance is stronger for the GTX 660. Overall we continue to see the GTX 660 perform exceptionally well.

Benchmarks - Aliens vs. Predator

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 25 | TweakTown.com

Aliens vs. Predator hasn't been super kind to the GTX 600 series, but you can see, the GTX 660 manages some strong numbers at 1920 x 1200 and 1680 x 1050.

Compared to the GTX 580 you can see we're lagging slightly while against the HD 7870 we can see that the numbers are near identical at all resolutions.

Rico Rodriguez returns as the protagonist, aiming to overthrow the evil dictator Pandak "Baby" Panay and confront his former mentor, Tom Sheldon.

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 26 | TweakTown.com

We can again see that performance between the HD 7870 and GTX 660 are extremely close here. On the playability level side of things we can see that 2560 x 1600 isn't an option, but below that we've got very strong numbers.

Benchmarks - Metro 2033

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 27 | TweakTown.com

You can see that the GTX 580, HD 7870 and GTX 660 are putting out almost identical numbers across the board here. That means that while 2560 x 1600 isn't an option, 1920 x 1200 and 1680 x 1050 looks good with some strong FPS present.

Benchmarks - Dirt 3

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 28 | TweakTown.com

We continue to see this trend where the HD 7870, GTX 580 and new GTX 660 perform very close to each other. We also see that while we fall shy of the numbers we need at 2560 x 1600, but 1920 x 1200 and 1680 x 1050 continue to not be an issue.

Benchmarks - Far Cry 2

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 29 | TweakTown.com

It's no surprise that across the board we've got very strong FPS here. Let's see what happens when we get into the AA and AF side of things.

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 660 2GB Reference Video Card Review 30 | TweakTown.com

Starting off with Mafia II you can see we manage to just sneak in that 60 FPS number at 1920 x 1200 for a solid gaming experience. Compared to the HD 7870 you can see we do trail behind by about 10% at this resolution with a similar loss being seen against the GTX 580.

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 31 | TweakTown.com

You can see under Aliens vs. Predator AA and AF just isn't an option at 1920 x 1200 let alone 2560 x 1600.The same is seen out of the GTX 580 and HD 7870.

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 32 | TweakTown.com

With AA and AF on we can see that we lag behind the GTX 580 and HD 7870 here with the latter card being able to do 2560 x 1600 with a minimum above 30 FPS.

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 33 | TweakTown.com

Like Aliens vs. Predator you can see that AA and AF again isn't an option when moving to an intensive engine like Metro 2033.

NVIDIA GEFORCE GTX 660 2GB Reference Video Card Review 34 | TweakTown.com

Just Cause 2 numbers line up with the HD 7870 again here and that means we manage to scrape a playable number in at 1920 x 1200. Of course just scraping in at 1920 x 1200 means that 2560 x 1600 isn't an option.

Final Thoughts

NVIDIA's GEFORCE GTX 660 isn't the dominant force that we feel the other GTX 600 series based video cards have hit us at during launch. Performance overall is extremely strong, but when we refer to the "dominance" that we've seen from the other models, the GTX 660 looks like it will hit at a price point near identical to the AMD Radeon HD 7870 and ultimately offers performance that is near identical to it.

The GTX 660 isn't going to cause the headaches for AMD like the other models we've seen. If the price point was in the lower $200 range or performance was overall maybe 10% faster than it would cause problems, but the price it's going to hit at that level and the performance it offers, it's ultimately sits perfectly against the HD 7870.

This is good news for AMD as they finally get a little bit of a break it seems as no doubt the last few months have been extremely stressful as NVIDIA ultimately beat AMD at their own game which consists of being more aggressive on the pricing side of things.

We're going to see partners offer pre-overclocked models at a slightly higher price point which in turn will help boost performance, but we've also got these options from AMD and its partners, too.

The one thing we really just need to find out now is the overclocking potential of the new model as that could be what ultimately separates the two models apart from each other. As always, though, that's something we'll be taking a closer look at soon enough. Stay tuned for that.

Overall the GTX 660 is just a really good video card that looks like it will come in at a really good price point. The HD 7870, though, is also a really good video card that comes in at a near identical price point. Of all the model battles in this generation of cards, the HD 7870 / GTX 660 is the closest thing to a coin flip when it comes to deciding what to buy.

It looks that no matter which one you buy, you're going to end up with a good product at a good price point. Does your blood run green or red? You get the drift.
