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.

Where did I call you an idiot? You took issue with my response to rarson, who fits my profile as someone who continuously ignores or is unable to understand some very simple concepts backed by mounds of evidence and historical data.Then he has the gall to question my ability to understand certain concepts? Of course I have trouble understanding opinions founded on stupidity. Unless you have the same problems, why would you take offense?

Here, I'll call him an idiot and a liar.He's an idiot and a liar.
He's been one forever.
It will never change.
As least David's butt is smakc full of his lipstick, and poor Goliath is rich as can be and the one still standing and alive.
I guess Galidou sucked too hard now David (amd) is almost dead.
Poor Galidou, supporting the underdog under it's jockstrap just hasn't worked out at all.
I have a feeling David's paramour might be a bit "upset" again, and again, and again, and again, and again.
Did the idiot get anything correct ?
Were his correction to his incorrect comments that he corrected not needed anyway since even after the corrections he issued to himself he was still wrong?
I'll answer that.
YES.

http://www.techpowerup.com/reviews/NVIDIA/GeForce_...20% more performance than last gen for the same price one year and a half later isn't a big deal either. Sure you win on thermal and consumption constraints.
You don't even know me personally and still you have to insult my intelligence, that's what fanboys do... and that's far worse than lacking of judgement in my opinion.
I admit that AT LAUNCH the 7970 was worse than the gtx 280 compared to last gen parts but you have to consider what's coming out too. And we all know they have this kind of information, and estimation of the performance of the part for the price.
So right, they should of priced 7970 400$ but that would of made another war with Nvidia(which already sued AMD for price fixing between them) so this price might just reflect the return to normal for both companies. No more 4870 BIG DEAL, back to normal, not because AMD want to price it BADLY because they have been sued to do so....

You get the first shot on new technology, you price it higher, you lower the price when the new stuff comes out. Same laws for both companies. 4870 was an unknown mistake, the chip wasn't out and the preliminary tests showed it performing way less than when it launched.It was a precipitated launch. Prices had been fixed WAY before the final product. With drivers enhancements and such the 4870 performed WAY above what AMD was hoping for, it was a surprise to them. They couldn't play too much with the price because it was already out in the medias for a while. Shit happens, they have been sued for being lucky with their final products for price fixin and next gen cards AHD to go up in prices breaking the amazing deal they sold for.

"I admit that AT LAUNCH the 7970 was worse than the gtx 280 compared to last gen parts but you have to consider what's coming out too."Finally, now was that so hard?

Worst increase in performance, not, gtx 680 is 20-25% average faster than gtx 580. Biggest increase in price, sure but do you know anything about price fixing between AMD and Nvidia, yep, the prices are fixed by both companies.Even if they were sued just before the days of radeon 4870 and gtx 280(thus explaining in part why the price of the 4870 wasn't adjusted to Nvidia because they were forbid to and were being checked) they continue to do that.

While speaking about all that, pricing of the 4870 and 7970 do you really know everything around that, because it seems not when you are arguing, you just seem to put everything on the shoulder of a company not knowing any of the background.Do you know the price of the 4870 was already decided and it was in correlation with Nvidia's 9000 series performance. That the 4870 was supposed to compete against 400$ cards and not win and the 4850 supposed to compete against 300$ series card and not win. You heard right, the 9k series, not the GTX 2xx.
The results even just before the coming out of the cards were already ''known''. The real things were quite different with the final product and last drivers enhancements. The performance of the card was actually a surprise, AMD never thought it was supposed to compete against the gtx 280, because they already knew the performance of the latter and that it was ''unnaittanable'' considering the size of the thing. Life is full of surprise you know.
Do you know that after that, Nvidia sued AMD/ATI for price fixing asking for more communications between launch and less ''surprises''. Yes, they SUED them because they had a nice surprise... AMD couldn't play with prices too much because they were already published by the media and it was not supposed to compete against gtx2xx series. They had hoped that at 300$ it would ''compete'' against the gtx260 and not win against i thus justifying the price of the things at launch. And here you are saying it's a mistake launching insults at me, telling me I have a low intelligence and showing you're a know it all....
Do you know that this price fixing obligation is the result of the pricing of the 7970, I bet AMD would of loved to price the latter at 400$ and could do it but it would of resulted in another war and more suing from Nvidia that wanted to price it's gtx 680 500$ 3 month after so to not break their consumers joy, they communicate A LOT more than before so everyone is happy, except now it hurts AMD because you compare to last gen and it makes things seems less of a deal. But with things back to normal we will be able to compare last gen after the refreshed radeon 7xxx parts and new gen after that.
Nvidia the ''giant'' suing companies on the limit of ''extinction'', nice image indeed. Imagine the rich bankers starting to sue people in the streets, and they are the one you defend so vigorously. If they are that rich, do you rightly think the gtx 280 was well priced even considering it was double the last generation... It just means one thing, they could sell their card for less money but instead they sue the other company to take more money from our pockets, nice image.... very nice..... But that doesn't mean I won't buy an Nvidia card, I just won't defend them as vigorously as you do.... For every Goliath, we need a David, and I prefer David over Goliath.... even if I admire the strenght of the latter....

I was wrong, Nvidia didn't sue over AMD, both companies were sued for price fixing but things are back now, anyway all this stuff is taking way too much of my time, you have your way of seeing things as facts, I have my way of seeing things as my opinion, I'll give you the benefit of the doubt because you're so much more intelligent than me and I don't care about the ultimate truth as I don't beleive in such a thing.Being sued back in 2008 in the times they were working on gtx2xx and 4870 series might explain the lack of information on each others and the reason why they couldn'T play with the price once they knew the surprise. They were probably forbid to adjust price based on each other performance for the benefit of the consumer. But the surprise of that SO small chip performing sometimes better than a gpu 110% bigger was a real shock for the small company.

You truly are an estrogen doused total licker bleeding red that no tamp can ever stop.Thanks for the pathetic entertainment.
Now you may whine some more in your sensitive little girl voice.

Wow, chizow's acolyte is back. I guess it's his troll name and when he can'T stand it anymore he logs with CeriseCogburn to insult people so he Chizow's name remain clean.Who's whining, when I read you, it seems that's all you can do whine whine whine.... read everything you ever wrote in the last 6 months and that's ALL you do insulting people and whining.... look in the mirror dude.
