The NVIDIA GeForce GTX 660 Review: GK106 Fills Out The Kepler Family
by Ryan Smith on September 13, 2012 9:00 AM ESTCrysis: Warhead
Kicking things off as always is Crysis: Warhead. It’s no longer the toughest game in our benchmark suite, but it’s still a technically complex game that has proven to be a very consistent benchmark. Thus even four years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and the answer continues to be “no.” While we’re closer than ever, full Enthusiast settings at a 60fps is still beyond the grasp of a single-GPU card.
Crysis has been a game that has consistently penalized Kepler for its lack of memory bandwidth. Nowhere was this more evident than the GTX 660 Ti, which thanks to its memory bus reduction took a significant hit. But as we alluded to in our introduction, there’s a corner case where the GTX 660 is going to be able to easily keep up with the GTX 660 Ti: ROP and memory bandwidth-bound situations. As a result we’re looking at the best case scenario for the GTX 660 when held up against the GTX 660 Ti, which sees the GTX 660 offer 95% of the performance of the GTX 660 Ti. Most games aren’t going to be like this, but in this one case the GTX 660 may as well be as good as the GTX 660 Ti as far as performance goes, which goes to prove just how bottlenecked Crysis is by memory bandwidth.
Looking at a more meaningful comparison, because the GTX 660 doesn’t take a memory bandwidth hit compared to the GTX 660 Ti, the resulting card is much more resource balanced which in turn impacts AMD’s ability to lead in this benchmark. AMD once again wins here with the 7870 taking the lead, but only by a relatively modest 7% margin. This is the first time we haven’t seen a comparable AMD card lead by a significant margin in this generation, which for NVIDIA is an improvement though still not a reversal of fortunes. At the same time however NVIDIA isn’t doing too much better than the 7850 here, beating AMD’s lesser 7800 by an even more modest 5%.
As for NVIDIA’s older cards, the generational performance gains are in-line with what we’ve already seen out of the other GTX 600 cards. Compared to the GTX 460 1GB for example, a card that launched over 2 years ago at the same price, performance is up by 50-60%. But unsurprisingly this is less than the performance gain going from the 8800GT to the GTX 460, a similar timeline jump that saw performance more than double. At the very least NVIDIA certainly has the 8800GT licked at this point (by nearly a factor of 4x), but this means they’re also at risk of perpetuating longer upgrade cycles for current GTX 460 owners.
Moving on to minimum framerates, our results are almost the same with one interesting twist: the GTX 660 is now beating the more expensive GTX 660 Ti. Why? As we mentioned earlier, because of the higher core clock the ROPs on the GTX 660 actually have a greater theoretical throughput than the ROPs on the GTX 660 Ti. Since we’re not seeing any other factors that would explain this difference (i.e. drivers) it’s very likely that the GTX 660’s faster ROPs are giving it the advantage here.
Though while this is enough to push the GTX 660 ahead of the GTX 660 Ti, it’s not improving the GTX 660’s situation relative to the 7800 series at all. The GTX 660 is still closer to the 7850 than it is the 7870 here.

chizow doesn't understand the concept of early adoption. He only mentioned rebates because that Nvidia rebate debacle has been beaten over his head time and time again.chizow - Friday, September 14, 2012 - link
Ah just a matter of time before the only idiot on the internet willing to defend AMD's laughable 28nm launch prices arrives to defend their honor.How do you feel now about those $550, $450, and $350 pricepoints you so vigorously defended when the 7970/7950/7870 launched?
And yes its important to mention the rebates because revisionists like yourself are so quick to forget the actual rebates, they only mention the price drops.
So just as I asked then, where's AMD's rebates given the floor has completely dropped from under their entire pricing structure just a few months after release, just as I predicted?

We did not vigorously defend the pricing scheme, we're just not seeing it as worse as you can see it, hence why we answer to you. Everytime I see people like you speak about AMD the way they do, I just see so much hate, when you start to say things like idiot and trying to say we're defending our ''honor'' you're past the point where your arguments are worth even a penny to me.If you have to disrespect people when speaking about video cards, there's one thing I have to say, you have a choosen side and it hinders your judgement. Stay respectful and I'll give you credit but now it's too late you just proved ourselves that you're not fit to judge well in this discussion.
Anyone know that a judge couldn't work on an affair of murder if the murdered one is in his own family because it... would severely hinder his judgement by putting emotions in the way. Disrespect to me is the worse form of acting when arguing. You lost it all there to me, I'm just sad I did reply to your previous messages without reading this one first, I would of just realized that it's too late for you.
AMD and Nvidia are both company trying to make money, trying to put one on a pedestal like if everything they do is related to god and thus is perfect... AMD's 4870 was a mistake, 7970 was a mistake, gtx 280 is related to god and it's AMD's pricing scheme that is at fault.
Everything AMD does is wrong, everything Nvidia does wrong is AMD's fault.... Like my 6800 gt that never worked properly with that Nforce 3 chipset, AMD's fault, that driver release that fried tons of Nvidia's video cards, AMD's fault, GTX 670's performance so close to GTX 680's performance, AMD's fault, 660 ti 192 bit bus and 24 ROPs, AMD's fault(I heard they stole them during the night and are not willing to give em back unless Nvidia pays a heavy ransom), Why isn't Nvidia making more money than Intel and Microsoft, AMD's fault, my grandfather's cancer, AMD's fault, wow, life is a bag full of surprise. Chozow's lack of respect calling us stupid, AMD's fault, we lost our honor because of... AMD's fault.....

Uh disrespect? You mean like you questioning very easily referenced facts like price and performance at every turn, or questioning how much I paid for a 2xGTX 670 or even that they existed with 680 PCB? Or questioning numbers only to be rebuked by a link from a widely respected website, only to question that website, then get provided with more benchmarks from one of the site you linked and question that one too?There comes a point you can't reason with people like you, so if you want to argue about emotional attachment leading to irrational behavior, you should really look in the mirror.
But what should I care, as you said everyone must look themselves in the mirror and be at peace with their own decisions in life, I can for a fact say I'm good with my buying decision this round, do you think one can say the same about buying AMD 28nm parts under their ridiculous asking prices, especially given all of the recent price drops?
Also, I have been critical of Nvidia as well with 28nm, so to say I think they can do no wrong, downright dishonest on your part. There's a reason I waited to buy my 670s instead of snatching them up at launch for $400, but then again, I've been at this long enough to make an informed decision.

''Uh disrespect? You mean like you questioning very easily referenced facts like price and performance at every turn, or questioning how much I paid for a 2xGTX 670 or even that they existed with 680 PCB''Nope, I mean calling other idiots: ''Ah just a matter of time before the only idiot on the internet willing to defend AMD's laughable 28nm launch prices arrives to defend their honor.''
End of the discussion, you're a disrespectful Nvidia fanboy, I doubted for the gtx 670 price you said because I was vigorously looking for a 670 but not a reference fan design, something with an aftermarket fan that will stay cool for a nice and quiet overclock.
For what you call facts, life turn around perception and interpreted by the brain. Women tend to dislike when their boyfriend cheat on them while in some country it's normal to have many wifes, know what I mean? Perception is something personnal, something might be bad and abnormal and seem like a fact from someone's standpoint but for another human being, it might be just normal dependnig on their choosen side, past experiences and emotions. If someone totally beleives 2+2 makes 5 and no one can convince him of anything else, then to him it's the truth. If the only truth to you is your truth, you will disagree all of your life with other peoples because they have a different point of view.
All I was discussing with you isn't that AMD is perfect and that their pricing is perfect, I was just defending my point of view, the way I saw things while saying ''TO ME IT SEEMS LOGICAL'' while all you had to say was ''REFERENCED FACTS, FACTS, FACTS, FACTS'' not caring about how I perceived things, I just hoped you could understand why I see things this way, I understand the way you see things because I can tell it seems logical to me but that isn't the way I see IT.

"End of the discussion, you're a disrespectful Nvidia fanboy."Please don't talk about respect when you can't even adhere to your own standards.
If you claim "TO ME SEEMS LOGICAL" while questioning my conclusions but ignoring facts and historical data that are relevant to the industry in general and graphics cards in particular, that suggests to me that your thought processes are not logical at all, but born of ignorance or subnormal intelligence.
After all, a simpleton can believe Unicorns and Fairies exist, but that does not make it so.
You brought up the GTX 280 again, yet once again you can't seem to understand the very key differences with the GTX 280 vs. 7970 launch prices. I've already outlined them, do I need to do so again?
Simple question, do you think Nvidia's pricing was worst at launch with the 280 than AMD's pricing with the 7970?

''You brought up the GTX 280 again, yet once again you can't seem to understand the very key differences with the GTX 280 vs. 7970 launch prices. I've already outlined them, do I need to do so again?''I brought that up?? You have to read back to realize you started it all again speaking of rebates and such which was the only reason why I answered to you to show that not everyone sees the way you do.
Maybe we could just state that Nvidia made a mistake by pricing the gtx 680 at 500$ because it was stronger than a 600$ card and then they are the faulty one as you usually see things.
''I've already outlined them, do I need to do so again?''
Well if you outlined them, if it was so different, why did you bring up the apst of the gtx 280 to compare to this different story in the first place?
Calling you an Nvidia fanboy isn'T disrespectful to me like calling other idiots defending their honor. It means you have a choosen side, maybe it might seem like it's an attack but it'S not, sorry if the hat fits your head.

Oh and I was wondering, for someone so informed about your purchases and everything, did you say you owned a gtx 280? For someone buying 330$ gtx 670 that's quite a fun ''fact'' considering you whined about the TOO LOW price of the radeon 4870, but no, you didn't get to buy one of those for 250$ on special, you got the gtx 280.... Fun stuff when the 4850/4870 were at the TOP of Performance/dollar charts, which was something we don't see often.....(fanboyism?)I'm an informed buyer which is why the only video cards I bought brand new at launch for me, my wife or friends are: Geforce ti 4200, radeon hd 9500 flashed to 9700 pro, 8800 gt, radeon 4850/4870, gtx 460 ti, radeon 6850/6870, gtx 660 ti and the radeon 7950 I super overclocked for my 3 monitors and skyrim :)
And yes there are ATI cards included in my buying decision which doesn't make me a Fanboy and helps my OPINION being undistorted by emotions thus the reason I'm not calling others idiots when speaking in forums related to VIDEO CARDS.

Since you love to make this about me, when it really isn't....Yes I bought a GTX 280 at launch but I waited a few days and got lucky on a Bing cash back promotion on Ebay. 35% Bing Cash Back, quite a few others got it as well (feel free to google it), brought the total to $420ish. Then Nvidia issued their big rebate after the 4870 launch, so I had the option of $120 check or $150 EVGA bucks, I took the cash.
So $300, minus the $220 I got for my 8800GTX on Ebay and I paid a whopping total of $80 out of pocket for the fastest single GPU. Early 2009 I got a 2nd 280 for $230 in a Dell deal after the economic crash that dropped prices on all GPUs....
Obviously not everyone would have been so fortunate, but if I didn't get 280s, I might very well have gotten 260s or waited for 285s.
