The GeForce GTX 660 Ti Review, Feat. EVGA, Zotac, and Gigabyte
by Ryan Smith on August 16, 2012 9:00 AM ESTMeet The Zotac GeForce GTX 660 Ti AMP! Edition
Our next GTX 660 Ti of the day is Zotac’s entry, the GeForce GTX 660 Ti AMP! Edition. As indicated by the AMP branding (and like the other cards in this review) it’s a factory overclocked card; in fact it has the highest factory overclock of all the cards we’re reviewing today, with both a core and memory overclock.

Zotac will be shipping the GeForce GTX 660 Ti AMP at 1033MHz for the base clock and 1111MHz for the boost clock. This represents a sizable 118MHz (13%) base overclock, and a 131MHz (13%) boost overclock. Meanwhile Zotac will be shipping their memory at 6.6GHz, a full 600MHz (10%) over the reference GTX 660 Ti. The latter overclock will stand to be very important, as we’ve already noted the GTX 660 Ti is starting off life as a memory bandwidth crippled card. Power consumption willing, the GTX 660 Ti AMP is in a good position to pick up at least 10% on performance relative to the reference GTX 660 Ti.
Like the EVGA card we just took a look at, Zotac’s GTX 660 Ti is based on NVIDIA’s reference board, so we’ll skip the details here. Rather than using a blower like EVGA however, Zotac is using an open air cooler – dubbed the dual silencer – that is well suited for a board of this length. The cooler uses a pair of 70mm fans, mounted over an aluminum heatsink that runs nearly the entire length of the card. Attaching the heatsink to the GPU itself is a trio of copper heatpipes, which transfer heat from the GPU to various points on the heatsink. Meanwhile the VRMs are cooled by a smaller, separate heatsink that fits under the primary heatsink; given the size and the location, it’s hard to say just how well this secondary heatsink is being cooled.
Altogether the card measures just 7.5” in length, an otherwise itty-bity card made just a bit longer thanks to some overhang from Zotac’s cooler. Zotac advertises their dual silencer as being 10C cooler and 10dB quieter than the competition, and while this may strictly be true when compared to some blowers, it’s not appreciably different than the dual-fan open air heatsinks that are extremely common on the market today. In fact among all of the cards we’re reviewing today this is unquestionably the most standard of them, as Zotac and several other NVIDIA partners will be shipping reference clocked cards built very similar to this. For this reason we’ll be using Zotac’s card as our reference card for the purpose of our testing.
Moving on, power and display connectivity is the same as with the GTX 670 and other cards using NVIDIA’s PCBs. This means 2 PCIe power sockets and 2 SLI connectors on the top, and 1 DL-DVI-D port, 1 DL-DVI-I port, 1 full size HDMI 1.4 port, and 1 full size DisplayPort 1.2 on the front.
Rounding out the package is the usual collection of molex power adapters and quickstart guides, along with a trial version of Trackmania Canyon. However the real star of the show as far as pack-in games goes will be Borderlands 2 through NVIDIA’s launch offer.
Wrapping things up, Zotac is attaching a $329 MSRP to the GeForce GTX 660 Ti AMP, which makes it a full $30 more expensive than reference-clocked cards and reflecting the greater factory overclock. This also makes it the most expensive card in today’s review by $10. Meanwhile for the warranty Zotac is offering a base 2 year warranty, which is extended to a rather generous full limited lifetime warranty upon registration of the card.

660 can go to 1100/1200 as easily as the 7950 gets to 1150 (so another 10% faster)..Check the asus card I linked to before. You'll have a hard time catching the 660 no matter what, it costs you also as noted by anandtech, my comments on watts/cost/heat etc.Memory bandwidth isn't the issue. here and all of it overclocks fairly close. We don't run in 2560x1600. It's not the weakness. That is a misnomer perpetuated by Ryan beating it like a dead horse when only 2% of users use any res above 1920x1200. I just debunked that idea further by showing even monitors at newegg including 27 inchers don't use that res. IE, no, bandwidth isn't the problem. Bad review on ryan's part, and no conclusion is the problem. The CORE clock/boost is the thing when it's not an bandwidth issue, and it's already been shown to not be true.. LOL, yep, nvidia conspiracy, the minimums were used here to...ROFL. Good luck digging for things wrong with 660TI. Minimums are shown at hardocp, guru3d, anandtech and more. Strange thing you even brought this up with no proof.
The NV cards have only been upped 100mhz, which is about ~10%, not 20 like you say. 915/1114 isn't 20%. You CAN get there, but not in out of box exp. I'd guess nearly all of the memory will hit 6.6ghz. Common for 7970OC / gtx680 to hit 7+ghz.

I said 20% because most of their cards are way above reference clocks, I was just representing the reality, not the reference thingys. When you can buy factory overclocked cards at the same price, let's say 10$ premium, mentioning the reference clocks is almost... useless. Plus over the internet, 80% of the reviews had factory overclocked cards so the performance we see everywhere and is in everyone's head, is close to 20% overclock has been done.So in fact there's maybe 10-15% of the juice left for fellow overclockers. I'm estimating, it could be more in the case of better chips. While the 7950 as we know it, has been reviewed everywhere on it's reference clocks/fan and if you take an aftermarket cooler and get, let's be honest and say 40%, it's far ahead in terms of comparison from the reference reviews we have.
And again and for the last time, it all depends on the games.

When I look at things again and again. the memory bandwidth doesn't seem to be much of a problem. The only games where I can guess it could harm it is any new games that will come out with directx11 heavy graphics. Something that taxes the cards on every aspects, else than that, for now, the card doesn't seem to have any weaknesses at all.I never thought that for the moment it was a real weakness for it, the future will tell us but even there, 90% of the gamers plays at 1080p or less and 80% of that 90% pays less than 150$ for their video cards. For those paying more, it all depends on choosen side, games they play, overclocking or not and money they want to spend.
Remove overclocking of the way Nvidia wins almost everything by a good margin. Anyone playing 1080p won't be deceived by any 200$+ card if they are not so inclined playing everything on ultra with 8x MSAA.

You're going to have a CRAP experience and stuttering junk on your eyefinity in between crashes.Come back and apologize to me, and then thejian can hang his head and tell you he tried to warn you.

Here's the WARNING for you again, with the 660Ti STOMPING your dreamy 7950 into the turf in Skyrim at 2560 x 1080http://www.bit-tech.net/hardware/2012/08/16/nvidia...
RussianSensation - Thursday, August 16, 2012 - link
Hey Ryan,In Shogun 2 and Batman AC at 1080P almost none of the new cards are being stressed. I think you should increase the quality to Ultra for the new 2-3GB generation of cards even if the < 1.5GB VRAM cards suffer and bump AA to 8X in Batman. Otherwise all the cards have no problem passing these benchmarks. Same with SKYRIM, maybe think about adding heavy mods OR testing that game with SSAA or 8xAA at least. Even the 6970 is getting > 83 fps. Maybe you can start thinking of replacing some of these games. They aren't getting very demanding anymore for the new generation of cards.
Ryan Smith - Saturday, August 18, 2012 - link
Russian, it's unlikely that we'll ever bump AA up to 8x. I hate jaggies, but the only thing 8x AA does is to superficially slow things down; the quality improvement isn't even negligable. If 4x MSAA doesn't get rid of jaggies in a game, then the problem isn't MSAA.Consequently this is why we use SSAA on Portal 2. High-end cards are fast enough to use SSAA at a reasonable speed. Ultimately many of these games will get replaced in the next benchmark refresh, but if we need to throw up extra roadblocks in the future it will be in the form of TrSSAA/AAA or SSAA, just like we did with Portal 2.

I was speaking a bit on both. The article insinuates that the 660ti is on the same performance level as the 7950. The obvious caveat to your results is that it is ridiculously easy to overclock the 7950 by 35-45%, and GCN performance scales pretty well with clock increases. It should be noted in the article that the perf of 7950 OC'd is beyond what the 660ti can attain. Unless you guys can OC a 660ti sample by 30% or more.CeriseCogburn - Sunday, August 19, 2012 - link
Is this the exact same way we recommended the GTX460 reviews ? With some supermassive OC in the reviews, so we could really see what the great GTX 460 could do ?NO>>>>>>>
The EXACT OPPOSITE occurred here, by all of your type people.
Did we demand the 560Ti be OC'ed to show how it surpasses the amd series ? NOPE.
Did we go on and on about how massive the GTX580 gains were with OC even though it was already far, far ahead of all the amd cards with it's very low core clocks ? NOPE - here we heard power whines.
Did we just complain that the GTX680 is not even in the review while the 7970 is ?
Nope.
How about the GTX 470 or 480 ? Very low cores, where were all of you then demanding they be OC'ed because they gained massively.. ?
Huh, where were you ?
Galidou - Sunday, August 19, 2012 - link
Performance scales pretty well on both design but AMD just is a little better at overclocking because it seems like the base clock is terribly underclocked. It just feels like that but that must be for power constraints and noise on reference designs.
