NVIDIA GeForce GTX 660 Ti 2GB Kepler Graphics Card Review

Author: Ryan Shrout
Manufacturer: NVIDIA

Power Consumption and Temperatures

With all the power efficiency improvement talk that NVIDIA has been pushing on us since learning about the new Kepler GPU, we were eager to see how the actual power consumption actually turned out.

View Full Size

Between the GTX 670 and the GeForce GTX 660 Ti we see a 14 watt power consumption difference - pretty close the 20 watts that NVIDIA claimed.  The Radeon HD 7870 uses only 16 watts less power while the HD 7950 is using 42 watts more.  This again shows us the power efficiency of the Kepler design, though maybe not as dramatically as the GTX 680 or GTX 670.

While these numbers are not directly comparable since the GeForce GTX 660 Ti is using a non-reference cooler, it does show us that the Kepler core can be cooled pretty easily.

nvidia has a beast of a video card with 660ti compared to 7950 even with an updated bios.

Thank you for sharing your info. I really appreciate your efforts and I will
be waiting for your next post thanks once again.

All the retailers say there are non listed. I hope I don't miss the wave before they oos :/

I am looking forward to the upcoming price drops from AMD. Isn't competition great!?

August 16, 2012 | 01:06 PM - Posted by mAxius

i cant wait till the fall/winter when amd releases the 8xxx series of cards then nv sits and waits for a year than updates its lineup

August 16, 2012 | 01:16 PM - Posted by APhamX

Low TDP, cuda cores, and the MSI Twin Frozr looks promising to overclock. I might just move on from my 6970 to this card. 1344 Cuda cores should help in AE rendering.

How much more performous would you get if you have a gtx 670 and want to run that with the 660ti as sli

August 16, 2012 | 01:57 PM - Posted by Terminashunator (not verified)

I doublt you can SLI a 660ti and a 670 together, and a 660ti is about 5-10% less powerful than a 670.

no you SLI a 660 ti and a 670 because are different cards you dick, you can only SLI the same card but they can be different makes. e.g MSI and EVGA, but they have to be the same GPU!

For building an SLI-System you need to use SAME GPUs.
2x GTX 670 OR 2x GTX 660 Ti.
GTX 670 + 660 Ti is not able to run in SLI-Mode.

These are in fact enormous ideas in about blogging. You have
touched some fastidious factors here. Any way keep up wrinting.

September 11, 2012 | 12:58 AM - Posted by YOYO (not verified)

660ti SLI is about a 20% performance increase from a single 680

Gtx 660 ti sli is in some cases even more powerful than the gtx Titan

August 16, 2012 | 01:46 PM - Posted by simieon (not verified)

how does sli scale on this card? will it be worth it towards highly oc'ed 600$ cards?

Hi, i play in a 25' Monitor, and i'm going to buy a 660Ti When the 660Ti goes "Cheap" here in Brazil ( A Lot Expensive here :\ ), but the question is i can Run the 660Ti i have risk of lose the 660ti With a 400w Power Supply ? with a core i3 2120 and 8 gb Kingston Memory ? Thank You. And Sorry for The bad english, i'm Training.

What brand PSU is it? A seasonic, thermaltake, or corsair 400w PSU likely would be okay, but the 660ti like a 450+. Other than that, your next upgrade would likely be a Quad Core i5, but even then the difference would be marginal between an i3 and an i5.

August 16, 2012 | 02:12 PM - Posted by João (XxLeloxX) (not verified)

I Have a Corsair, but i was seeing that probably i will need to change my power suplly, i have Corsair 400CX, that only have a 6 pin connector.

Will faster GPUs help productivity with Folding at Home?

August 29, 2012 | 01:35 PM - Posted by Anonymous (not verified)

If you use the GPU-Client it will. The faster the card, the more points you'll get.
But in Folding@home the Radeons are much faster, then the GTXs.

Question for Tom:
Do you think the 660 has been nerfed enough so that overclocked versions won't exceed a more expensive 670? Because that was a real problem with the 670 vs 680!

August 16, 2012 | 02:47 PM - Posted by Arb (not verified)

at lower rez like 1080 don't think would take much OC to get it to around 670 speed, but that disabled memory controller is a ~25% memory bandwidth hit which would be a pretty size-able OC to get that back. I would say it could get in 670 ball park. This card was aimed at single monitor people.

wish i haddent bought a hd 7850

Why the 660Ti is between the 7870 and 7850 check out a real review on

August 16, 2012 | 05:28 PM - Posted by Anonymous (not verified)

Unless I missed it in my rather quick glance at this review (which has been discarded because of this fact), you should have included the 560 Ti. Did you just assume that no one was interested in the increase of power between the generation gap?

Should have used the 560 Ti, 570, and a 670 as a bench mark competitor - this review is useless with out it.

September 9, 2012 | 11:37 AM - Posted by Anonymous (not verified)

560ti is marginally faster than the 470.

August 16, 2012 | 07:57 PM - Posted by Angry

You missed it, because its quiet obvious with as close as the 660ti performs to the 670.

And that comparison probably in the works anyway....

August 16, 2012 | 08:15 PM - Posted by Anonymous (not verified)

what Catalyst version you used for the test?

August 17, 2012 | 10:29 PM - Posted by Ryan Shrout

12.6 for AMD, 305.37 for NVIDIA.  Article updated!

Can this one card be used to drive an HD TV, and 3 monitors in or out of eyefinity? I want to display a TV on on screen and have 3 monitor computing, not hardcore gaming but along those lines. I don't play many games, but I'm looking for a card that can do this. I currently run 3 heads off of a 6950/70 and run the TV off the z68 gigabyte iSSD mobo. THe current setup works, but I'm looking to upgrade...

I am planning a build which will use 3 660ti's in a 3 way SLi configuration so I should find out just how much of an improvement that makes in the next year. Your next question is why? Well I am not as interested in the performance gain as I am interested in getting at cheap GPUs. I am building the computer as mainly a GPU compute platform its ability to serve as a gaming platform is a perk. I am looking to take advantage GPU processing capabilities for GIS work.

interesting, what type of data?

September 9, 2012 | 02:17 PM - Posted by Anonymous (not verified)

*HELP* Can it handle 3 monitors???? *HELP*

September 16, 2012 | 10:23 PM - Posted by Anonymous (not verified)

it can handle 4, 3 at once for gaming and one on the side

December 11, 2012 | 03:41 PM - Posted by Gunner690 (not verified)

It's my understanding that a 660Ti is a crippled 670gtx on a 192bit bus. So why? can these cards not SLI? surely the 670 would reduce its bus speed down to 192. before you go saying whats the point (I picked up a 660ti for £80 Black friday on Amazon) two 660ti's beat a 670gtx in most youtube benchies.

I'm going to buy gtx 660 ti but,I don't know which version of gtx660ti is the best. I'm thinking about gigabyte gtx660ti 3gb (gv n66toc 3gd)

March 10, 2013 | 07:29 PM - Posted by Macabre (not verified)

As of right now, the HD 7870 is $80 less than the 660 Ti on Newegg. I don't think that $80 is worth the performance difference at all.
