The GeForce GTX 660 Ti Review, Feat. EVGA, Zotac, and Gigabyte
by Ryan Smith on August 16, 2012 9:00 AM ESTOC: Power, Temperature, & Noise
Our final task is our look at the overclocking capabilities of our GTX 660 Ti cards. Based on what we’ve seen thus far with GTX 660 Ti, these factory overclocked parts are undoubtedly eating into overclocking headroom, so we’ll have to see just what we can get out of them. The very similar GTX 670 topped out at around 1260MHz for the max boost clock, and between 6.6GHz and 6.9GHz for the memory clock.
| GeForce 660 Ti Overclocking | |||||
| EVGA GTX 660 Ti SC | Zotac GTX 660 Ti AMP | Gigabyte GTX 660 Ti OC | |||
| Shipping Core Clock | 980MHz | 1033MHz | 1033MHz | ||
| Shipping Max Boost Clock | 1150MHz | 1175MHz | 1228MHz | ||
| Shipping Memory Clock | 6GHz | 6.6GHz | 6GHz | ||
| Shipping Max Boost Voltage | 1.175v | 1.175v | 1.175v | ||
| Overclock Core Clock | 1030MHz | 1033MHz | 1083MHz | ||
| Overclock Max Boost Clock | 1200MHz | 1175MHz | 1278MHz | ||
| Overclock Memory Clock | 6.5GHz | 6.8GHz | 6.6GHz | ||
| Overclock Max Boost Voltage | 1.175v | 1.175v | 1.175v | ||
As we suspected, starting with factory overclocked cards isn’t helping here. Our Zotac card wouldn’t accept any kind of meaningful GPU core overclock, so it shipped practically as fast as it could go. We were able to squeeze out another 200MHz on the memory clock though.
Meanwhile our EVGA and Gigabyte cards fared slightly better. We could push another 50MHz out of their GPU clocks, bringing us to a max boost clock of 1200MHz on the EVGA card and 1278MHz on the Gigabyte card. Memory overclocking was similarly consistent; we were able to hit 6.5GHz on the EVGA card and 6.6GHz on the Gigabyte card.
Altogether these are sub-5% GPU overclocks, and at best 10% memory overclocks, which all things considered are fairly low overclocks. The good news is that reference-clocked cards should fare better since their headroom has not already been consumed by factory overclocking, but binning also means the best cards are going to be going out as factory overclocked models.
Moving on to our performance charts, we’re going to once again start with power, temperature, and noise, before moving on to gaming performance.
Unsurprisingly, given the small power target difference between the GTX 670 and the GTX 660 Ti, any kind of overclocking that involves raising the power target quickly pushes power consumption past the GTX 670’s power consumption. How much depends on the test and the card, with the higher power target Gigabyte card starting with a particular disadvantage here as its power consumption ends up rivaling that of the GTX 680.
We also see the usual increase in load temperatures due to the increased power consumption. The Zotac and Gigabyte cards fare well enough due to their open air coolers, but the blower-type EVGA card is about as high as we want to go at 80C under OCCT.
Last but not least, looking at noise levels we can see an increase similar to the temperature increases we just saw. For the Zotac and EVGA cards noise levels are roughly equal with the reference GTX 680, which will be important to remember for when we’re looking at performance. Meanwhile the Gigabyte card continues to shine in these tests thanks to its oversized cooler; even OCCT can only push it to 46.8dB.

I absolutely will ignore driver support for the 6 series cards. If you are using an AGP card, it's really REALLY time to upgrade.You are just as bad a fanboy for nVidia as any AMD guy here, moron. You are completely ignoring anything good about AMD just because it has AMD attached to it.
I'm completely confident that if AMD had introduced adaptive v-sync and PhysX, you would still say they suck, just because they came from AMD. If you read my post, it says that 660 Ti IS more powerful than the 7870. I was just pointing out that they are closer than they seem. I have no nVidia hatred, they have a lot of cool stuff.
And about the 660 Ti beating the 7950 at 5760x1080, look at the other three benchmarks, moron. The 7950 wins all of them, meaning BF3, Dirt 3, and Crysis 2. It only looses in Skyrim by and average of 2 FPS. Why didn't you include those games in your response.
And when I left the games out, I said that they merely blew the average out of proportion, but that you can't leave them out because you want to. You still have to calculate them in the total. Moron.
And for the record, I'm running a GTX 570, moron.

Look, the amd crew, you, talk your crap of lies, then I correct you.That's why.
Now, whatever you have that is "good by amd" go ahead and state it. Don't tell lies, don't spin, don't talk crap.
I'm waiting...
My guess is I'll have to correct your lies again, and your STUPID play dumb amnesia.
The reason one game was given with 660Ti in that highest resolution winning is very obvious, isn't it, the endless your bud giradou or geradil or geritol whatever his name is was claiming that's the game he was buying the 7950 for...
LOL
ROFL
MHO
Whatever - do your worst.

" Fan noise of the card is very low in both idle and load, and temperatures are fine as well.Overall, MSI did an excellent job improving on the NVIDIA reference design, resulting in a significantly better card. The card's price of $330 is the same as all other GTX 660 Ti cards we reviewed today. At that price the card easily beats AMD's HD 7950 in all important criteria: performance, power, noise, heat, performance per Dollar, performance per Watt. "
LOL
power target 175W LOL
" It seems that MSI has added some secret sauce, no other board partner has, to their card's BIOS. One indicator of this is that they raised the card's default power limit from 130 W to 175 W, which will certainly help in many situations. During normal gaming, we see no increased power consumption due to this change. The card essentially uses the same power as other cards, but is faster - leading to improved performance per Watt.< br />Overclocking works great as well and reaches the highest real-life performance, despite not reaching the lowest GPU clock. This is certainly an interesting development. We will, hopefully, see more board partners pick up this change. "
Uh OH
bad news for you amd fanboys.....
HAHAHHAHAHAHAAAAAAAAAAAAAA
The MSI 660Ti is uncorked from the bios !

"I don't have a problem with that. 660Ti is hitting 1300+ on core and 7000+ on memory, and so you have a problem with that.The general idea you state, though I'M ALL FOR IT MAN!
A FEW FPS SHOULD NOT BE THE THING YOU FOCUS ON, ESPECIALLY WHEN #1 ! ALL FOR IT ! 100% !"
So you have not a problem with performance? good, because actually that means its a competitive card, not a omfg card. And if you want to oc a 660 you would just oc a 7950 so I don't see the omfg nvidia is so much better.
"Thus we get down to the added features- whoops ! nVidia is about 10 ahead on that now. That settles it.
Hello ? Can YOU accept THAT ?"
So essentially when i ask how many people do actually 3D because you seem to think 2% is unimportant in resolution your answer is "well nvidia is 10 ahead because it has features ACCEPT BLINDLY". Not smart.
"Nope, it's already been proven it's a misnomer. Cores are gone , fps is too, before memory can be used. In the present, a bit faster now, cranked to the max, and FAILING on both sides with CURRENT GAMES - but some fantasy future is viable ? It's already been aborted.
You need to ACCEPT THAT FACT."
FPS are gone and future is fantasy? amd cards still perfom, they are very gpgpu focused and they do excellent for that, and still they don't have bad gaming performance while doing it because you just buy a pre OC version or something and you get still awesome performance (very similar to your 660ti god), say to me what is not enjoyable while playing with an AMD card mr fanboy.
And the future, well, future is gpgpu because allows big improvements to computing, yet is "fantasy". It's only non important because nvidia had good gpgpu in the past and not now?
"Okay, so whatever that means...all I see is insane amd fanboysim - that's the PR call of the loser - MARKETING to get their failure hyped.."
Yeah, calling fan-boy before actually noticing that nvidia told the reviewers how to review the card so it looked better, because get realist, if they include a horrible AA technique with no reason at all something is behind the table hiding you know. Haven't you noticed? theres a lot of discrepancy in 660ti's benchmarks around the web, from sites where the 660 loses to 870's radeons and where it wins to 970's, there is not a single liable review now, do you want to see the truth? buy a 660ti a 870 and a 950, and compare the 3, you will have the truth, thay they perform like they are priced and AMD cards are not shit.

Hey, I answered the guys 3 questions. I made my points. I didn't say half of what you're talking about, but who cares.
The guy killed himself with point #1, so that's the end of it.
CeriseCogburn - Saturday, August 25, 2012 - link
Oh stop the crap. nVidia is 10 features ahead, I'm not the one who talked about resolution usage, so you've got the wrong fellow there.3D isn't the only feature... but then you know that, but will blabber like an idiot anyway.
Go away.
claysm - Saturday, August 25, 2012 - link
"I'm not the one who talked about resolution usage". You can't fault him for mixing up his trolls. Since almost everything you and TheJian have said is complete shit it's hard to keep track of who said what.And if you can objectively prove that I've lied about anything, I really would like to see it. And I mean objectively, not your usual response of entirely subjective 'AMD suckz lololol' presented in almost unreadably bad grammar.
I take that back, I won't read it anyways, since I know already know it'll be an nVidia love fest regardless of what the facts state. And I'll reiterate that I'm using an nVidia card. Moron.

Oh it is not, he showed it all to be true and so does the review man.Get out of your freaking goggled amd fanboy gourd.
Look, I just realized another thing that doesn't bode well for you..
What nVidia did here was make a very good move, and the losses of amd on the Steam Hardware Survey at the top end are going to increase....
The amd fanboy is constantly crying about price - they're going to look at $299 with the excellent new game for free and PASS on the more expensive 7950 Russian is promoting EVEN MORE now.
Here let me get you the little info you're now curious about. ( I hope but maybe you're just a scowling amd fanboy liar still completely uninterested because you never got 1 fact according to you LOL sad what you are it's sad)

" Looking at Steam Survey, it is clear why AMD is so desperate. GTX680 has 0.90% share, while even the 7850 lineup has less, just 0.62%. If you look at the GTX670, it has 0.99%. The HD7970 has only 0.54%, about half of what GTX680 has, which is funny considering that the GTX680 is selling only half the time compared to HD7970. It means that GTX680 is selling 4 times faster."
ROFL...
No one is listening to you fools, Russian included... now it's going to GET WORSE for amd....

forgot link, sorry, page 2 commenthttp://www.anandtech.com/show/6152/amd-announces-n...
Okay, and that stupid 7950 boost REALLY IS CRAPPY CHIPS from the low end loser harvest they had to OVER VOLT to get to their boost...
LOL
LOL\
OLO
I mean there it is man - the same JUNK amd fanboys always use to attack nVida talking about rejected chips for lower clocked down the line variants has NOW COME TRUE IN FULL BLOWN REALITY FOR AMD....~!
HAHHAHAHAHAHAHAHHAHA
AHHAHAHAHAHAA
omg !
hahahahahahhahaha
ahhahaha
ahaha
Holy moly. hahahahahhahahha

plus here the 660Ti wins in 5760x1080, beating the 7950 the 7950 boost, and the 7970...http://www.bit-tech.net/hardware/2012/08/16/nvidia...
Skyrim. So, throw that out too - add skyrim to your too short shortlist. Throw out your future mem whine. throw out your OC whine readied for 660Ti...
Yep. So the argument left is " I wuv amd ! " - or the more usual " I OWS nVidia ! " ( angry face )
