Seven GeForce GTX 670 Cards, Benchmarked And Reviewed

Gigabyte N670OC-2GD

Gigabyte's N670OC-2GD employs the company's Windforce 3X cooling solution on a GeForce GTX 680 PCB. Although GeForce GTX 670 only needs two six-pin power connectors, Gigabyte deploys one six-pin and one eight-pin plug on this model.

After paving the way for a potentially-screaming overclock, Gigabyte only sets a 980 MHz base clock with an average GPU Boost frequency of 1059 MHz. Its 2 GB of GDDR5 memory run at the reference 6008 MT/s data rate, meaning performance, overall, should be pretty similar to what we'd expect from a reference card.

During testing, we overclocked this card to a 1059 MHz base clock quite easily, so we are somewhat surprised by the conservative factory overclock.

The extremely light Windforce 3X cooling solution gets optimized in time to make it onto Gigabyte's GeForce GTX 670 card. We did have a less-than-favorable experience with our Windforce-equipped GeForce GTX 680 sample, but modifications to the temperature-dependent fans help bring acoustics back under control. Both GPU-Z and our ears suggest that the changes we suggested last time around made it into the GeForce GTX 670 design.

Instead of a very audible 40% fan duty cycle, similar to what we've seen on the Radeon HD 7870 and GeForce GTX 680 prior to Gigabyte's firmware update, this card's fan starts at 20%, or 810 RPM. Along with Asus' board, Gigabyte's Windforce 3X-cooled GeForce GTX 670 is one of the quietest cards in this round-up at idle.

Though it employs three fans and is easily the longest submission, the N670OC-2GD is so light that it doesn't require a supporting frame or a back-plate.

Gigabyte's solution almost begs to be run in SLI mode, as it's the slimmest two-slot card we're testing today.

    Where is the msi gtx 670 power edition?

    Typo on conclusion. "not to loud on loud." That would be the Gigabyte card.

    On the Gigabyte card's page:

    During the course of our testing, we effortlessly set this card to run at 1059 MHz, so we're not sure why Gigabyte held back so much. During testing, we overclocked this card to 1059 MHz quite easily, so we are somewhat surprised by the conservative factory overclock.

    This seems to be saying the same thing twice. Error, or am I missing something?

    hey man,where's MSi Twinfrozer IV OC edition?

    The roundup was published in German on May 22, 2012:,testberichte-241027.html

    Sorry, but at this time (and 4 weeks later too) MSI was unable to deliver one of this cards. When MSI starts so late with this cards, then this is not our fault. ;)

    Please do this with the 680s

    Also, the second chart on the 'Sound Level and Temperature: Overclocked' page is missing the 'Mhz' label on the speed for the Palit card. It should read '1059 Mhz', while it reads only '1059'.
  • LonelyMan
    I'd like to see one for the 680s too, in which the 680 classified and lightning will be present, including others. :D

    please also do battlefield 3 benchmark!

    I've been waiting for this review.

    So glad I bought the ASUS GTX 670 2 weeks ago now :)

    All cards were tested for our charts too (with BF3). Please wait a little bit, our team will update this results soon. :)

    My phone shows me the right content :D iPhone? :D

    Love the video's on the graphic card sounds.

    I am wondering, if it would make any difference for sound if the video card's fans were pointing down, instead of pointing at the side. Or if the fan's sound profile, would change because of the orientation of the card.

    Where is this test lab located at? Middle East? Here in the US, most popular brands nVidia GPU are EVGA, MSI and I don't see they're on the list. That stopped me reading at page 2. Good night.

    there have been some reports and rumours that retail 670/680 are achieving much less overclock/boost than the review samples.

    can you take a look at that?

    "Rather, we suspect a driver problem. There doesn't seem to be any other explanation."

    Tired of this kind of selection bias where any aspect that is subpar is dismissed as a driver issue. Another explanation is the spec sheets are misleading or the conclusions you have about what to expect from extra hardware capacity are wrong.

    I would like to read GTX 680 comparison too, and using PCIE 3.0 spec :)

    thanks man,team toms FTW!
  • Hmm... no EVGA ? :(
  • Formata
    Gigabyte GPUs have been really solid for the last few generations of nVidia cards. No signs they are letting the quality slip, which is great news.
  • TheBigTroll
    this helped me decide what 670 to get.
  • weatherdude
    Excellent comparison. The videos are especially useful. The Asus card is very impressive. I mean just wow.
  • deejaybos
    I JUST ordered my EVGA FTW card after reading reviews on Newegg. I saw too many negative reviews on the ASUS based on the fact that their factory overclock was resulting in all sorts of video errors because of whatever reasons. People suspect it's because it was being pushed TOO far on the ASUS O.C.
