Power, Temperature, & Noise

Having seen the gaming performance of these cards and the limited gains from their factory overclocks, let’s move on to power, temperature, and noise. If these cards are going to differentiate themselves it needs to be accomplished by factors the manufacturers have more control over, and their respective coolers are a good way to do it.

Idle Power Consumption

With our cards spanning the full spread of possibilities – semi-custom, custom, and custom with heavily modified power delivery – even load power consumption starts separating the cards to at least a small degree. Although it’s just a minor difference, MSI’s GTX 770 Lightning has the lowest power consumption of the three in Battlefield 3, beating every GTX 770, including the lower clocked stock GTX 770, by at least a few watts. Since we are memory bandwidth limited in BF3, and thereby performance limited, for better or worse these cards can’t get too far from each other. But for a few watts difference we’re in all likelihood looking at general chip-to-chip variation rather than some intrinsic advantage in any one card, even with the use of custom components.

FurMark on the other hand shows some larger differences, but as this is our stress test what we’re really seeing is the difference in the cards’ regulated TDP. MSI’s 260W TDP means they have a larger power budget to work with, draw more power, and don’t get throttled quite as hard as the other cards. The end result being that FurMark is not particularly useful in comparing cards in this case. Otherwise the difference between the EVGA and Gigabyte cards is larger than we’d expect even with chip to chip variation, which may mean Gigabyte’s Ultra Durable component selection has some impact under maximal workloads.

Idle GPU Temperature

Moving on to temperatures, despite the difference in both the number of fans and the size of said fans, the end result has all of our cards perfectly tied under BF3. Every card tops out at 66C, EVGA, MSI, and Gigabyte alike. Open air coolers as a general design are difficult to improve on, so despite everyone’s efforts, unless someone uses a wildly different fan curve than the others then any well designed open air cooler should perform similar. Notably, because every card tops out at 66C, they’re all well below the thermal throttle point on the GTX 770 of 80C. This means no card ever throttles, which can be useful for squeezing out a little more performance out of what’s otherwise the same GPU.

Meanwhile FurMark temperatures are less than useful here for the same reasons as power. Gigabyte and EVGA top out at 74C and 75C here respectively, while the higher TDP MSI card tops out at 78C. Though this does go to show that even in our stress test none of these cards reaches the 80C throttle point.

Idle Noise Levels

Finally looking at our noise results, we find that unlike our performance data there’s some clear and meaningful separation between the cards, especially between the EVGA card and the remaining two cards. For whatever reason the EVGA card hits 47dB under BF3, a hair louder than even the blower based reference GTX 770. Admittedly the Titan cooler on the reference GTX 770 is overbuilt for a card of this configuration, and as such over performs and is by no means easy to catch, but it does mean that EVGA isn’t gaining anything over the blower from a noise perspective. It’s no worse, it’s just not any better, which indicates that EVGA’s ACX cooler may not be scaling down very well.

MSI and Gigabyte on the other hand manage to beat EVGA and the reference GTX 770 by 2-3dB, a small but not insignificant amount. The winner here is Gigabyte at 43.8dB under BF3, followed by MSI at 44.8dB. These noise levels aren’t going to be silent, but they’re also not too far off of it. For the level of performance these cards offer it’s a fairly impressive outcome, albeit the typical one for the open air cooler tradeoff.

Speaking of silence, when it comes to idle noise every card is actually a bit worse than the reference GTX 770 here, owing to NVIDIA’s single fan and use of materials. The roughly 40dB results aren’t by any means bad, but they aren’t going to get as close to being silent as NVIDIA’s reference blower.

In summary, differences in TDP aside all three cards are solid, similar performers when it comes to temperature and power consumption. However when it comes to noise under load, both Gigabyte and MSI have an edge here over EVGA and the reference GTX 770, which for stock performance does give these cards a small but meaningful lead over the competition. Gigabyte is the best performer in this respect, although MSI is right behind them. At the same time however this means that despite the difference in the designs of their coolers – 3 smaller and 2 larger fans respectively – it isn’t creating a practical difference between the Gigabyte and MSI cards.

    Ryan: Thank you for the quality review. From time to time, AT includes a table that shows relative performance and pricing of GPUs in AMD's and nVidia's GPU offerings. Would you include such table in this article? Reply
  • Ryan Smith - Friday, October 04, 2013 - link

    Those tables are typically only used in what we consider "primary" reviews.

    For reviews and roundups of individual cards like this, we are less interested in how it compares to competitive cards, and more interested in how the reviewed products compare to other cards in the same product family. E.G. we've previously established how GTX 770 compares to 7970 and the like, but how do the individual 770 cards stack up?

    Thanks for the review Ryan. I understand your reasoning for not including wider comparisons. For me, however, I always read GPU articles with an eye to "what does this mean for me?"...specifically, how is my 7950 boost holding up. I could wish for a better memory, I could open another tab and spend a few minutes pulling up past reviews...and I could wish that round-up and capsule reviews threw in a couple old charts (no reviewer comment or analysis needed), perhaps as an addendum titled "gpu overview" or "the big picture".

    Two games, one favoring AMD and one Nividia, would be great... or even a link to past charts for convenience. Anyway, great reviews...this isn't really a criticism, its just something I would like to see...

    For something like that we have Bench. You can compare any cards we have in our results database, and it always contains the latest data we have collected.

    nice...never noticed that feature before Reply

    Ryan, how did you increase the max boost voltage from 1.2 to 1.212v? (Which app). I use afterburner but even though I move the voltage adjuster to 1.212, it reports at 1.2v.

    Btw, I picked up the 4gb version of the evga 770 (FTW) based on this review & the memory over clocks you saw, and it too is reaching 8+ghz on the memory.

    And, yes, your Bench comparison tool is great and quite helpful.

    I just want to add my story. I get paid over $87 per hour working online with Google! I work two shifts 2 hours in the day and 2 in the evening. And whats awesome is Im working from home so I get more time with my kids. Its by-far the best job I’ve had. I follow this great link >>>> uttr.it/ukvczrq Reply

    Your comments about software from MSI, Evga and Gigabyte are a little strange as there is nothing at all stopping you from using any of their overclocking software on any of the cards mentioned. I use MSI Afterburner on my other branded cards all the time, it even works on laptops. Reply
  • jordanclock - Friday, October 04, 2013 - link

    The point is that this software is part of what you're paying for when you purchase these cards. It's part of the value of the whole package. You could easily swap the heatsinks and fans, but those are still valid points to raise when reviewing the product as a whole. Reply
