SLI Conclusion: GTX 660 Ti vs GTX 670

DX11: Battlefield 3

In Battlefield 3, players step into the role of the Elite U.S. Marines. As the first boots on the ground, players will experience heart-pounding missions across diverse locations including Paris, Tehran and New York. As a U.S. Marine in the field, periods of tension and anticipation are punctuated by moments of complete chaos. As bullets whiz by, walls crumble, and explosions force players to the grounds, the battlefield feels more alive and interactive than ever before.

The graphics engine behind Battlefield 3 is called Frostbite 2, which delivers realistic global illumination lighting along with dynamic destructible environments. The game uses a hardware terrain tessellation method that allows a high number of detailed triangles to be rendered entirely on the GPU when near the terrain. This allows for a very low memory footprint and relies on the GPU alone to expand the low res data to highly realistic detail.

Using Fraps to record frame rates, our Battlefield 3 benchmark test uses a three-minute capture on the 'Secure Parking Lot' stage of Operation Swordbreaker. Relative to the online multiplayer action, these frame rate results are nearly identical to daytime maps with the same video settings.

Colin, you need to get a 2560 display if you're going to bench with this much horsepower! Those Korean monitors on E-bay are a great value right now!

IS it possible that nvidia needs to perform a driver update as well?

# RE: weird?Olin Coles 2012-08-21 07:30
Who's Colin? As I (Olin) mention in the article, a larger resolution would merely mean a larger difference in results. There was enough evidence to indicate the outcome at 1680x1050 and 1920x1080, so 2560x1080 would have just pushed the SLI sets even further apart. As for the driver update, anything is possible but I don't think that there's too much room for improvement on a fourth-generation Kepler product.

I've got one of those 27 inch Korean monitors :)... and I can't go back to playing on a 1900 X 1080p monitor...

Where are the reviews to compare them in sli on a single monitor at 2560 X 1440/1600 resolution?

Just bought a 670 gtx over a 660 ti... because i am fairly certain that the 670 gtx in sli will CRUSH a 660 ti sli configuration.

Need to see numbers please!

# my opinionmatt 2012-08-21 13:29
if you're going for a 2 graphic card solution and you're already willing to drop the money on 2 $400 cards coming out to $800 total already, i don't see a reason not to just jump up another $200 and gain what i can only imagine will be an even bigger jump, by going with a 690.

like you mentioned once you go for an sli build the 660 loses it's shine, and (this is just my opinion) once you're already talking about an investment that big, i don't see any reason not to go for the ultimate when it's only $200 more.

i feel the 660 ti was always meant to be a very value oriented card, and when you're running sli it's a $600+ investment, to me that's a pretty sizable purchase for graphics cards, so i don't see very many people really wanting to sli them, it's simply not who i think nvidia was attempting to appeal too.

i myself intend to settle with a single 660 ti after seeing this, as jumping to a 670 isn't worth it, and jumping to 2 660 tis would make me want to climb the price ladder until i was at a 690 because again to me that seems like the best true value for extreme graphics solutions.

660 Ti of great value when you purchase the 3 GB model and overclock. Just like when I take my intel 960 i7 to 4.2 ghz and have it perform at a 980 level. OCing is the way to go

You will reduce the lifespan of your pc overclocking too much.

I fried my xps m1730 sli years ago with only moderate overclocking

on just the graphics cards.

It's a gamble as we know, some cards are better then others and some have issues.

# RE: my opinionRicky 2013-02-16 06:02
660TI SLI makes a lot of sense actually... $600 vs $999 and for $1000 less you are only losing about 20 frames. 670 SLI makes 0 sense considering there is only a 10 frame difference. 660TI SLI is actually the best value by far...

You'll have the chance to make a review of the 660Ti FTW+ (3GB)? Would be very cool to see a proper review of this card.

I believe this card, overclocked, is better than 670 FTW.

Keep doing this great reviews. =D

Perfect solution for the graphs Olin. Very nice.

One thing that has me a little worried about trusting the results that show only AVG FPS is that we don't know the low FPS.

For instance, if you get an average of 48FPS, that's plenty, but if every time an explosion goes off you dip to 15FPS, then that's no good at all.

On the other hand, perhaps I am misinterpreting avg fps as a viable benchmark for how a card will play a game?

So in framerate performance tests that use the exact same scenes to benchmark results for all video cards, you're worried that there's a mysterious point in which one card will suffer a frame rate loss that somehow won't affect all of the other cards?

You should take a good look at how these people test videocards:

Just running benchmarks simply doesn't cut it anymore, you need to play the games to see which cards gives the best experience... you might be in for a surprise.

And you really should have tested 2560 X 1440/1600 resolution, if you are going to buy a 660ti/670 sli setup then you won't be playing at 1680x1050, it's just ridiculous.

Just my 2 cents.

That's a good point, and if it is true that all cards will render the exact minimum frame rate relative to their average frame rate ratio between each card, then we could calculate exactly what the minimum frame rate would be on each card--given we know one cards minimum frame rate!

How can I tell what the minimum frame rate will be with the current information?

I actually could care less what the average FPS is when buying a card to play games. I need to know what the minimum fps are so to maintain fluid game play throughout each scene.

For instance, if the average frame rate is 50 and the minimum is 18, that's a potential red flag.

If a card tests 40fps average over all tests and then tests minimum 18fps in the same test, that's a definite flag.

# key term: relative performanceOlin Coles 2012-08-21 20:35
I could test any card on my system using my settings and report the results, but that won't mean anything unless you use the exact same hardware and software. That's why we use the average to compare relative performance, since it contrasts the differences between products tested under the same circumstances.

Much like the charts, you're making much to do over nothing.

# Why we want lowest FPSChris 2012-12-17 10:32
Olin, it is a valid point about the lowest FPS. To give an example, let's say that the two SLI setups run a test (BF3 example) at 124 vs. 112 FPS. Particularly based on the criteria you set out at the beginning, based on memory throughput, it's important to know if those results indicated either:

1. A consistent 10.7% increased framerate for the 670 SLI setup... or...
2. A scenario during the test where the 660 TI SLI setup dropped down to 20 FPS for a few seconds due to the bandwidth being flooded.

Either of those two scenarios could produce the difference we see in the average FPS. From a gaming perspect, 112 FPS is plenty... but 20 for brief moments during game play could reduce the quality of play significantly, whereas a floor of 60 FPS would not.

# single card till price dropsdave gray 2012-10-02 15:15
the new superclocked 660 ti is little more than the 660 ti and boosts around 5% to 6% I'm going with that and when prices drop, pick up a 2nd card. At present I don't play over 1680x1050 but will go to 1920 x 1080 when VA or IPS monitors improve response times and by then the 2nd card for sli should have dropped 25% or more

# SLI or not??Rich M 2012-10-07 09:41
So I am I correct in saying that if you are going for the single card option the 6600ti is a better value? I really don't have $600+ to blow on 2video cards, I can build an entire decent system with the $300+ savings from the one card. The costs will even go higher for the sli being mobo and psu costs more money as well. I don't compete as mush as I used to, so will the 660ti be better suited for me?

# RE: SLI or not??matt 2012-10-07 10:17
read the review, he says point blank on the last page, for a single card configuration the 660ti is a better deal then a single 670. don't got $600 for graphics cards? then don't sli them, cause if you're going with sli the 670's a better deal anyways.

# 670 longterm availabilitycaleb 2012-10-10 17:56
Here is my main issue and the only reason I am hesitant to jump on the 670 as opposed to the 660. Two years ago around xmas I got a really good deal on a 470 and have been very pleased with it ever since. However now that I am looking for a little more horsepower, there is not a 470 to be had anywhere while you can still find 460's for sli. Would this likely be an issue in another year and a half to two years when I would want to sli a 670?

only time will tell that, but with the lower price point, + being released later on (and therefore closer to the next generation of cards) i'd bet 660s n 660 tis will be easier to find then a 670 down the road, since demand for them won't slow down as much, since again they're newer.

I think saying the 660 Ti could keep up with a 670 if it's OC is a misreading of every DX11 benchmark graph in this entire review. The 670 is blowing the 660 Ti away and you're not even reviewing an OC version of the 670 like a FTW edition. It looks like you just don't want people to realize how close the 670 is to the 680 in these charts and you're hoping for a price drop.

I see absolutely no reason to get a GTX 690 at $999 when you can run 660 ti's in a 3 way sli configuration for $100 less than a 690 and get even higher frame rates. Heck even 2 way sli 660ti's are a better deal considering you'll be running any game at ultra settings over 100 fps and for $400 less than a 690, which you'll get maybe 20-30 more frames than the dual 660s. If getting 20-30 more frames is worth paying $400 extra to some of you, you have issues or absolutely no understanding of monetary value. Anyway here's a link where they compare dual/triple sli config 660ti's to several other cards including a GTX 690. The differences are so not even remotely worth $999 or even paying extra for dual 670s.

# you're missing some other factors.matt 2012-12-06 11:56
take into consideration the additional power requirements that 3 way sli set up would need. the 690 uses 300 watts the 660ti uses 150 allegedly, however you can overclock it quite a bit and pull closer to 220, which means you'd want enough overhead on the power supply to leave aside 660 watts just for graphics. on top of needing 6 6 pin cables.

you've already covered that extra $100 difference for the most part, in just the cost of a higher end power supply. now think of the real world cost of running it at 450-660 watts, the electrical cost also works against you.

then you have the fact that 2 way sli tends to run smoother then 3 way sli, and last but not least think of airflow. 3 cards take up quite a bit of space in the case and restrict the airflow far more then a single would, as well as increase the noise levels dramatically.

i'd say the 690 is worth it if you really intended to choose between those set ups. and as an added bonus you get to say you have the best, rather then a pretty wicked set up.

# RE: you're missing some other factors.Greg 2012-12-06 22:32
@ Matt, that's definitely a fair point with the power consumption and I honostly don't know anyone who runs triple sli, just all things considered you're gonna get better performance than a single 690 for about the same price with a higher power supply in mind and if power supply isn't an issue it's 100 bucks saved.

Also I just don't see any reason to get a $999 card when you can run double for cheaper and get near to the performance. I myself just have a single 660 ti and have no problems running games like The Witcher 2, BF3 on Ultra settings @ 1920x1080 with no frame rate issues.

If you have some crazy 3 screen setup running 2560x1440 and you're into graphic design, then yea I can see that as a good reason to go with a 690, otherwise why? Bragging rights? I just don't see much of a graphical or performance differece once you're hitting at around 80fps and beyond or don't really care I guess. There's just absolutely nothing out there where you need a 690 or even running sli to max something out.

# RE: RE: you're missing some other factors.matt 2012-12-06 23:04
it really is all about bragging rights for the most part, that and future proofing your system. some people have nothing better to blow there money on, or want the absolute best, even if they don't realistically need it. others figure 1 epic card now is the same cost as a new epic card in 2 years + a 680 today, so why not grab it and not have to worry about it when money may be tighter in the future?

but either way you look at it, the 680s and 690's aren't orientated toward budget minded users anyways. they're all about power users and enthusiasts. people like you and me aren't their target consumer.

# 660ti sli with 670gtxG-string8086 2012-12-12 11:06
Is it possible to sli,

x1 660ti (same gpu, mem, cores etc just 192bit,
with x1 670gtx of the same spec 256bit?

I have a PNY xlr8 660ti 2GB xlr8 (Amazon black Friday 80) + with an unecessary 20 pnp

and an evga 670gtx non ftw 2Gb 288

basically all that appears to be different is one is 256bit and the other 192bit.

My first test was an epic fail, as windows 8 crashed (my opinion is w8 is an epic mode would not work.)

Windows will boot with both cards sli'd just haven't had time to do a full test.

btw its only a gap stop until I can get another 670gtx

my 850w is old school from 2009 so having to split rails isn't my prefered method but works.

If it works I will still gain better fps in Crysis 2, Heavens bench etc, just the 670gtx reaches 107fps which seems weak in Heavens Bench 3

so anyone had any success?

I don't know what test result your looking at because the gtx 660 ti smashed the 670 in every benchmark in sli. The 660 ti scaled nearly perfectly double the frame rate. The 670 was a fare margin under double frame rates, go back and have another look.
