Meet the GeForce GTX 760

As we mentioned earlier, due to its 170W TDP the GTX 760 is essentially a drop-in replacement for the GTX 670 in board designs. Even NVIDIA’s reference design reflects this, with the reference GTX 760 being based on the reference GTX 670’s cooler and PCB. Consequently there’s not much to say about the GTX 760’s design that we haven’t said before. If you’ve seen a GTX 670 then you’ve seen a GTX 760, down to the last screw. For consistency we’ll quickly go over the GTX 760’s design, but this is generally a rehash of what we’ve already said about the GTX 670.

Like GTX 670 before it, GTX 760 is another “small” GK104 design. The complete card is 9.5” long, however the actual PCB is far shorter at only 6.75” long, 3.75” shorter than the GTX 770’s PCB. In fact it would be fair to say that rather than strapping a cooler onto a card, NVIDIA strapped a card onto a cooler. Meanwhile we see that once again NVIDIA is using Hynix R0C (6GHz) GDDR5 RAM here.

The cooler itself is fairly simple, utilizing an aluminum heatsink melded with a copper base plate. A separate heatsink covers the VRM circuitry – once again mounted at the front of the card – while the fan hangs off of the rear of the card. This unfortunately is the same fan as on the GTX 670, which means it makes a faint grinding sound at low RPMs. This design has proven more than adequate for the GTX 670s, though it does leave some room for NVIDIA’s partners to improve on overall cooling performance, especially with open air coolers.

Elsewhere at the top of the card we’ll find the PCIe power sockets and SLI connectors. Two 6-pin PCIe sockets provide the necessary external power, while a pair of SLI bridge connectors at the other end allow for up to 3-way SLI. NVIDIA’s standard I/O configuration also makes an appearance here, offering 2x DL-DVI, 1x HDMI, 1x DisplayPort 1.2.

Looking at clockspeed bins for a moment, it comes as no great surprise that like the GTX 770, the GTX 760 operates at 1.2v at its highest stock clockspeed bin. The higher voltage versus the 1.76v limit on the 600 series causes power consumption to jump up more rapidly at the highest bins, but is necessary to unlock the 1100MHz+ clockspeeds the card is capable of.

GeForce Clockspeed Bins
Clockspeed GTX 770 GTX 760
1162MHz N/A 1.212v
1149MHz 1.212v 1.2v
1136MHz 1.2v 1.187v
1123MHz 1.187v 1.162v
1110MHz 1.162v 1.15v
1097MHz 1.15v 1.137v
1084MHz 1.137v 1.125v
1071MHz 1.125v 1.112v
1058MHz 1.112v 1.1v
1045MHz 1.1v 1.087v

Finaly, for overclockers there is one further bin (1162MHz) available via overvolting to 1.212v. The maximum power target meanwhile is 115%, for a final power limit of 195W.

    Last year I was debating going 570 SLI and buying a second one, or selling it and going for a single 680. I went with the latter and am glad. I spent a lot of research on the decision, and 570 SLI is slightly lower than a single 680, within 90-95% depending on game. So if the 770 beats the 680 by a solid 5-10% (again, depending on games), it's going to really beat 570 SLI.

    Yeah. Im thinking i might stick with a single card. Maybe i should hold off and wait for the 760 Ti that will inevitably come. Really the GTX570 is a great card, its just getting a little long in the tooth, and frankly im kind of spoiled, I always want to make sure any game i can play runs at max settings as far as shadows/textures, etc. I'm apparently the only person on the planet who hates AA (makes things fuzzy), so i typically play most games at 1920x1080 with all settings maxed, 0xAA and 8xAnisotropic. The 570 is doing fine in that respect on everything i play now, i'm just worried about some of the upcoming games like BF4, Witcher 3, etc.

    I usually prefer to stay with single cards, i've just seen way too many situations where SLI didnt work (i.e. game didnt support it), produced poor results, etc. Not to mention the heat, and power consumption issues.

    Regardless, thanks guys for your responses, really helped me clarify the issue.

    Off Topic, im currently running an i7-2600k @ 4.1ghz stable, do you think im fine as far as CPU goes for these future games? Haswell doesn't seem to be a huge jump over Gen3 i7.

    Nfarce is spot on about 570 SLI, though 580 SLI can definitely beat a 680
    (1.5GB 580s are quite cheap on eBay these days, eg. I've seen them go for
    as little as 190 UKP total for two). Assuming you're familiar with the
    difference between a 570 and 580 performance-wise, then with respect to
    Firestrike Extreme, see the lower graph on this page:

    http://www.legitreviews.com/article/2201/9/

    and compare to the following 580 SLI results I obtained (check the
    Graphics scores; the overall scores are skewed against me a bit as my
    system is just a quad-core, though in this case I end up with better
    overall scores anyway vs. a 680, even with the 580s @ stock):

    Stock: http://www.3dmark.com/fs/588100
    Oc'd: http://www.3dmark.com/fs/518352

    For reference, here's just one 580 at stock, showing that it's Graphics
    score matches the article's 580 quite nicely:

    http://www.3dmark.com/fs/588046

    Also, my oc'd 580 SLI Graphics score matches a 780. :D (4506 vs. 4483)
    However, as many would rightly point out, the 780 has a huge VRAM advantage
    which is ideal for games like heavily modded Skyrim (though of course there
    are 3GB 580s, but they tend to cost more - mine was 170 UKP total whereas
    1.5GB 580s normally go for around 100 to 125 UKP), and further differences
    mean a 780 would likely be quicker in other cases, especially if you wanted
    to run a multi-screen setups with AA, etc.

    I haven't bothered running normal Firestrike until now, so here are stock
    and oc'd runs for comparing to the upper graph on the legit page:

    Stock: http://www.3dmark.com/fs/588907
    Oc'd: http://www.3dmark.com/fs/588883

    At stock, 580 SLI easily beats a 680. Oc'd, the Graphics score is well
    ahead of a 780 (infact it's higher than the Titan). This suggests, as one
    might expect, that as the visual load becomes more complicated, a single
    better card like a 780 will shows its strengths, ie. SLI'd 570/580s are
    good at typical HD res, but at resolutions like 2560x1440 a newer card
    would be more sensible.

    There's also the issue of power consumption if you added a 2nd 570; in
    the long term, would the additional electricity cost end up being not that
    much less than the cost difference compared to just upgrading to a single
    newer card? Hard to answer this as elec prices vary wildly by location.
    There's also the extra heat, and as you say the issue of which games run
    well in SLI since not all do.

    Btw, here's an oddity: changing the SLI rendering mode can have a
    dramatic effect on Firestrike Extreme scores, eg. while still at stock
    speed, here are my two 580s using Alternate Frame Rendering 1 (AFR1),
    compared to the earlier link which uses NVIDIA Recommended (examine the
    individual test results):

    http://www.3dmark.com/compare/fs/588100/fs/588603

    Graphics Test 1 doesn't change, but Graphics Test 2 increases by some
    36%, hence the Graphics score shoots up 20% from 3625 to 4363. On the
    other hand, the Combined Test drops by about 10%. I notice this test uses
    a lot of VRAM, so perhaps AFR1 doesn't handle heavy VRAM loading so well.
    I checked by running normal Firestrike with the two different SLI modes,
    the result was identical, suggesting that AFR1 may be better if a game is
    taxing VRAM resources a lot, ie. it may be worth manually experimenting
    with one's games to see if a different SLI mode gives higher performance.

    I tested with 3 cards aswell; the variation in results depending on SLI
    mode is even more pronounced (not checked with 4 cards yet, need to move
    them into the 3930K case). For the sake of completeness, here's the link
    (done with rather low 825 core clocks as the M4E mbd used has no spare
    slots to permit decent oc'ing with 3 cards):

    I read a piece yesterday which suggested NVIDIA wasn't going to release
    any more cards this year, but who knows, that could easily change. It
    would certainly be unusual if they didn't come out with a 760 Ti at some
    point, or something equivalent.

    :D:D Me too.

    > ... I'm apparently the only

    That can certainly happen with some games. Best to experiment with the
    various options. Back when I was playing Oblivion on a 22" CRT at
    2048x1536, I indeed found it better to leave AA off (because the dot
    pitch was so small, no AA at the high res looked quite good). However,
    with the games I'm playing now (FC2, Crysis2), turning on AA does look
    better, but yes some modes are better than others.

    If you don't plan on upgrading your display to a higher res, then adding
    a 2nd 570 would work quite well performance-wise, but on the other hand...

    > situations where SLI didnt work (i.e. game didnt support it), produced

    ... those are all very valid points to consider. Mind you, your CPU is
    running at quite a low clock, so extra heat shouldn't affect your CPU config,
    unless you have a very simple cooler.

    > Off Topic, im currently running an i7-2600k @ 4.1ghz stable, do you think
    > im fine as far as CPU

    A 2600K will easily run at 4.5 to 4.8 depending on the chip, and many will
    run at 5.0+, so you have plenty of scope for boosting your CPU performance
    should you feel that necessary. The limitation on how high it can go is more
    likely to be determined by your PSU, mbd, RAM, CPU cooler config and of course
    just general luck of the draw re the particular 2600K you have.

    You have done your research very wrong.

    I had GTX570 and GTX670 in the past. The performance gap was a consecutive 33 % in favor of GTX670 in 20 different games. Documented that in the forums.

    Meaning GTX680 is 50 % faster than GTX570.

    So SLI GTX570, if scaling is from 50 to 100 %, should be always ahead of GTX680.
  • skgiven - Sunday, August 4, 2013 - link

    Comparing against last years reference GTX660Ti (915MHz) has little merit - most (>90%) of 660Ti's are non-reference and boosting to 1200MHz is fairly standard (22% more than 980MHz)! The most recent 660Ti's are even sweeter on the power.
    Including a recent FOC 660Ti and some lesser cards in SLi (GTX 650 ti Boost, which wins hands down and 460) would have made for a very nice review.
    The 760 wins in high bandwidth games, but not low memory dependent games and apps, and not in terms of Performance/Watt.
    BTW. I'm not seeing the price comparison, even now the GTX660Ti is still much less expensive.

    doesn't look like much of an improvement compared to my overclocked 7850 that i bought for $250 over a year ago..
  • Parablooper - Wednesday, June 26, 2013 - link

    Wow. On 1080p Battlefield it beats a 7970... $270 price point vs. $400.... I like AMD but they better make a move soon or they're off the market.
  • king-dubs - Wednesday, June 26, 2013 - link

    It doesn't. Anandtech is still using 7950/7970/7970GHz results from pre-12.11 drivers.

    http://tpucdn.com/reviews/NVIDIA/GeForce_GTX_760/i...

    Also the 7970 dropped briefly to ~$300 two days ago, and the 7950 (Sapphire Dual-X) is still at $259 after MIR @ Newegg.

    Guru3D results are consistent with TPU:

    The 7970 results are with Catalyst 13.5 B2 (freshly composed for the GTX 780/770 reviews).

    The 7950 results are with Catalyst 13.6 B2 (freshly composed for this article)
