Test Setup And Benchmarks
The closest-performing card to the GeForce GTX 660 Ti in Nvidia’s prior-generation line-up is GeForce GTX 580. So, we obviously wanted to include it in our tests. Of course, we also want to see how this new model compares to GeForce GTX 670 as well.
AMD's similarly-priced Radeon HD 7870 is an obvious contender, as is the more expensive Radeon HD 7950. We're throwing the Radeon HD 7970 in as a reference point, too. We had MSI's R7970 Lightning and R7950 on-hand to represent those two products, and we dropped each card's clock rates to reference levels. MSI supplied the GeForce GTX 680 Lightning specifically for this review, and we tested it at stock and factory overclocked settings, too.
From here, things get more complicated. AMD is attempting a preemptive strike against GeForce GTX 660 Ti in the form of Radeon HD 7950 Boost Edition. Essentially, this is a BIOS update to the vanilla Radeon HD 7950 that overclocks the board from 800 to 850 MHz and implements a 925 MHz boost state. The accelerated frequency is adjustable in the Catalyst Control Center's overdrive tool.
We’re not going to spend a lot of time talking about the Radeon HD 7950 Boost Edition because, frankly, we're not fans of such last-minute retaliations. Company representatives claim 7950 Boost Edition cards will be available by Friday. But the last time we were promised availability of a Boost Edition card (the 7970), AMD was about a month too ambitious. We'll believe this one when we see it. You'll find the card's results in our overclocking tests as a result.
Speaking of overclocking, we're including MSI’s GeForce GTX 660 Ti a second time, its core accelerated an impressive 150 MHz and memory running 250 MHz faster thanks to MSI's Afterburner tool. We were able dial in an extra 100 millivolts on the core and set 114% of the maximum board power in order to get there.
Finally, we are looking to find the highest playable settings in each game that deliver a minimum of 30 FPS and an average of at least 40. We don't want to waste GPU performance on rendering hundreds of frames per second, and we aren't interested in numbers that aren't playable.

Hmm. I have been wanting to replace my 560 - this throws a wrench in the gears. I was sold on a ASUS 670 but I think I'll wait to compare specs with their 660ti - I just started ripping my BD collection so the additional RAM bandwidth might be worth the extra $100 but it is still an interesting option.Reply
so, this is basically a card that costs 40$ less then a GTX 580, consumes 100W less power then a gtx 580 and its 8% better...hmm, intresting.Reply
*edit, costs 100$ less then GTX 580.Reply
That's strange - on techpowerup review the 660Ti is above 7950's average performance.Reply
game junkyI was sold on a ASUS 670 but I think I'll wait to compare specs with their 660ti.Asus' DCU2 Top ends up about 5% faster than stock, 8% slower than stock GTX 670 and still uses that excellent cooler.Reply
Still, the GTX 660Ti looks to be a decent card.
Not really fond of how nVidia keeps nerfing their memory bandwidth though.
Once prices drop a little, I could see it being an excellent mainstream card.
nice card, not OVERLY impressed...Reply
BUT THE PRICE...!
c'mon SON let's be real here......
ridiculous @ $300 beans..
waiting for a price cut down.who's with me?Reply
I have been holding to upgrade my GTX 460 256bits. I wonder if this card will be bottlenecked by my C2Q 9550 @ 3.6ghz....Reply
GPGPU = Kepler = FAIL....Reply
that's depressing but I understand nVidia has designated GTX 6 series as a gaming cards but c'mon SON.!!!
ridiculous once again..
Clearly we need more price cuts on the 660ti. I expect AMD to lower the prices even more, heck online retailers sell Radeon cards lower than the MSRP, making 7950 and 7870 even more budget friendly. It's still sad really to see mid-range cards battling at $300+. It used to be $250 and lowerReply
