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.

@ 720p the lower range of cards (ATI 78XX etc.) will destroy framerates even with everything turned up, there is no need to waste time benching!!!!!!!!!!!zlandar - Thursday, August 16, 2012 - link
Anyone notice how the 7950 went from 69 fps at 2560 x 1600 on the 5/10/12 review to 85 fps on today's review? That simply from improved driver performance?Ryan Smith - Thursday, August 16, 2012 - link
Correct. Beginning with Catalyst 12.7 AMD's Skyrim performance has significantly improved.thegr8anand - Thursday, August 16, 2012 - link
Just wondering, Toms say the performance of 660 is 3-4% below 7870 while Anand says its 10-15% more. What gives??Ananke - Thursday, August 16, 2012 - link
This is a castrated effectively 128-bit 24 ROPs hugely overpriced card. Best Buy had it for several days already, it is in the same green box as 560ti, and apparently nobody paid attention it was taken to the sale floor :). So, some people :):) already bought it, tried it, and can confirm it is not worth the money asked. In my sole opinion it can justify max. $199 at launch. It is disappointing. So, for whoever has and feels OK, GTX 670 for $400 is the way to go, otherwise pick up Radeon 7950 or 7870. I personally will choose the AMDs because of compute, NVidia current generation computing just plain sucks, but if you only play one game BF3 :):):) then maybe several hundred dollars is OK to spend on the GTXs.silverblue - Friday, August 17, 2012 - link
It's a 192-bit memory bus, not 128-bit.Different reviews have different setups. Toms seems to be the exception as regards the 7870 being superior; in general, the 660 Ti comes closer to the 7950. In some titles, it's shockingly fast.
If there was to be a standard 660, all NVIDIA could do here is to cut down the number of shaders and texture units - clocks won't do it as you'll just clock them back up again, and memory is already nerfed.

"Closer to the 7950"?? Careful, sounds like ignoring the evidence. BEATS it, and usually the 7970 (even ghz at times) too...see all my other posts...Pointless to even respond here?.. I've already written every game at hardocp, anand show victories for Skyrim, Batman AC, Witcher2, Battlefield3, Battlefield 3 Multiplayer, Portal 2, max payne 3...That rules out HardOCP I guess. Anand added a few more, Shogun 2 (another landslide for 660 TI, even against 7970), Dirt3 used here anand - Wash (though minimums do show Nvidia as Ryan points out)...
Civ5, landslide again at 1920x1200 here anandtech...Metro2033 here anandtech, <5% win for Nvidia %1920x1200 (I call it a wash I guess)...
So which game can I point to that will be OK to you? I'll try to help you let AMD win...:)
Understand Tomshardware, turned all cards to default...So you buy a card and downclock them all to test...ROFL "we dropped each card's clock rates to reference levels." from page 2 of their article:
http://www.tomshardware.com/reviews/geforce-gtx-66...
That same page 2 from their review at the bottom of the graphics card list:
"All overclocked cards reduced to reference specification for testing"
So, every card will perform UNLIKE what you would buy on either side. Their review is worthless as they are nerfing even ATI cards. Though it hurts NV more. I'm not sure why they even ran the benchmarks...They should have just said look elsewhere for real answers to how these will perform when you buy them out of the box. Nobody else did this, which is why they are ODD in their results.

That's great them Tom's Hardware can put 100% or near so amd cards in their bang for buck monthly again perpetuating the big lie, jiggering the price categories up or down depending on what makes amd fanboys gleeful. It's so ridiculous they get best card for 115, best card for 155, then next month, best card for 90, best card for 135 ETC, and then they squish the crap amd card in just uner the number, and their attached price link shows it 50 bucks higher on the day of their postYou thought this place was bad ? LOL
Then the rabid amd fans at toms put a minus 20 on every comment that doesn't kiss the amd quite often. They're goners.
They do have more than 1 reviewer, so some times you'll get something sane, but not very often. It's been degrading for a long time, it's really sad.

nVidia's profits and sales show very few people are amd fanboyyed out like you are.I recommend not believing nor following a word of advice from you.
claysm - Friday, August 17, 2012 - link
It has a lot to do with what settings are being used in-game. The Tom's article admits at the end that their setup could be AMD favored, since they tend to prefer high levels of AF and AA, which eat up memory bandwidth and heavily tax the memory subsystem (a strong point for AMD).
