GeForce GTX 660 Ti Review: Nvidia's Trickle-Down Keplernomics

SLI And CrossFire, Compared

Now that we know how a single GeForce GTX 660 Ti fares, it's time to consider the performance of two rendering cooperatively. We're adding two GTX 660 Tis in SLI and a pair of Radeon HD 7950s in CrossFire to each game chart.

Of the seven games tested, one doesn't seem to work with CrossFire at all. All seven support SLI.

Although the GeForce GTX 660 Ti loses to the Radeon HD 7950 most of the time in our single-card testing, a pair in SLI manages to outperform the 7950s in CrossFire three times out of seven (one of those clearly because CrossFire isn't working properly). Lets dig a little deeper, though. In Batman, CrossFire simply doesn't do anything for the AMD cards. In Battlefield, one GTX 660 Ti beats one HD 7950, so we'd expect two cards to demonstrate a similar outcome. Skyrim is really the only outlier, and we know that it's largely processor-dependent. Combine that knowledge with the experience of CrossFire having higher overhead and it makes more sense that the GeForce cards would shift into the lead.

    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.

    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.

    That's strange - on techpowerup review the 660Ti is above 7950's average performance.

    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.

    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.

    I have been holding to upgrade my GTX 460 256bits. I wonder if this card will be bottlenecked by my C2Q 9550 @ 3.6ghz....

    GPGPU = Kepler = FAIL....
    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 lower
