Nvidia GeForce GTX 980 Ti 6GB Review

Power Consumption

Power Consumption Measurement for Different Applications

We measure the power consumption of these graphic cards as described in The Math Behind GPU Power Consumption And PSUs. It's the only way we can achieve readings that facilitate sound conclusions about efficiency. Once again, we’re using picture galleries to provide a detailed breakdown of the results across all the rails and connectors for those interested.

When you look at the tables, bear in mind that the overall results for all rails is not calculated by adding the numbers in the column above them. The maximum or minimum figures do not always occur at the same time on all rails. So, the overall results represent how high the power draw was across all rails at the same time.

Idle and 2D Desktop

Power consumption comes in at 10W, which is certainly good. However, based on observing the individual rails, it’s also clear to see that there are many load fluctuations. The 10W result is really just the average of a lot of ups and downs.

 MinimumMaximumAverage
PCIe Total0.98W 30.24W 7.44W 
Motherboard 3.3V0.94W 2.11W 1.01W 
Motherboard 12V1.20W 12.60W 2.20W 
Motherboard Total2.12W 13.66W 3.21W 
Graphics Card Total5.12W 38.33W 10.35W 

Gaming Loop

Aside from stress testing (and depending on the game, of course), this is where we see the highest power consumption. A measured average of 233W is a little higher than the GeForce GTX Titan X’s 224W. This doesn’t really come as a surprise though, since Nvidia's GeForce GTX 980 Ti boosts its core clock rate a bit higher than the Titan X after it warms up and reaches its temperature target.

 MinimumMaximumAverage
PCIe Total34.16W 358.80W 184.05W 
Motherboard 3.3V1.19W 3.43W 2.26W 
Motherboard 12V20.16W 80.52W 47.17W 
Motherboard Total22.27W 83.03W 49.43W 
Graphics Card Total66.08W 428.38W 233.48W 

Stress Test

The GeForce GTX 980 Ti’s TDP is 250W, according to Nvidia. But it never reaches that number under normal conditions, except in certain professional applications. None of the usual stress tests manage to push it past the 254W mark. Taking the 233W gaming power consumption into consideration, 19 to 22W of headroom remain for overclocking. These are just idle musings for a reference-class GeForce GTX 980 Ti, though, since it runs into a thermal limit anyway. There’d be a bit more headroom with a higher-capacity cooling solution, even if this one is optimized for Nvidia's 250W cards.

 MinimumMaximumAverage
PCIe Total30.24W 236.88W 199.57W 
Motherboard 3.3V1.32W 3.30W 2.24W 
Motherboard 12V22.80W 70.56W 52.41W 
Motherboard Total24.91W 72.67W 54.65W 
Graphics Card Total65.24W 296.84W 254.22W 

Nvidia should be commended once again for doing a great job limiting its new card’s power consumption via the motherboard’s PCIe slot to under 75W. Load spikes, which we often see even from mainstream graphics cards, are practically nonexistent. Dynamic power distribution across the rails functions perfectly and without a hitch.

Power Consumption Overview and Comparison to Other Graphics Cards

Here’s a lengthy comparison of where the GeForce GTX 980 Ti stands compared to its competition.

    I'm writing this as seriously as I can, not being a fanboy: What is the purpose of the Titan X at this point? It lost its DP performance that made it a fantastic workstation-gaming hybrid. Also, it really sucks for people who bought a Titan X just a little over a month ago? That's ~$350 down the drain pretty much. Yea the Titan X has all that extra VRAM, but for what? 3 4K displays maybe, at which point a 980ti SLI would probably lose by about ~5% due to a few less CUDA cores.

    Again though, for most customers, the 980ti is the obvious choice. I just feel like nVidia totally screwed over most of their Titan X customers now. And why? Well, I really think the 980ti will be the cheaper answer to AMD's Fury or whatever Fiji will be called, Really interested to see how it will do. If Fiji beats the Titan X/980ti, it's rumored $800 price point would make the 980ti a somewhat compelling offer depending on how well it does.

    In the end, I'm loving this competition!

    How important is gaming to you if you spend $500 on GPU and $500 on a monitor?

    I guess i am the only one paying for rent out there.

    i personally find 4k at sub 48 inch stupid... but than again, i had 800x600 monitors at 15 inches and played some games at 640x480 on 17 inch screens, i also played ps1 games, so once hd came around and was single gpu at 1080p i had no issues whatsoever with jaggies any more.

    im not paying 500+$ for AA
    im also not sacrificing that much processing power for AA
    hell im 1920x1200 at 24 inch... i dont use aa.

    granted, a monitor could last you 5+ years if you get a good one so you can see it as an investment, and a gpu, im learning more and more if you sell your high end gpu the moment a new high end gpu comes out, you can get a sizeable upgrade every year for under 100$ and you over all come out ahead.

    sorry im tired as hell, i just realized i dont know which way to meant your comment to be taken.

    If you don't have $1000 of discretionary income each year, you need a better job. Better question would be, what adult doesn't have $1000 for a graphics card and a monitor?

    And this is exactly why I've been waiting to buy a new vid card and display.

    Wowza.
  • Eggz
    SOOOOO glad you're finally including the 780 ti in the graphs again! There were a lot of people with this card, and excluding it from the Tom's graphs made things harder to assess. Thanks!
  • damric
    This GTX 980 Ti seems significantly better price/performance than the GTX 980. I will be recommending these for higher end builds.
  • photonboy
    My first considered card since my GTX680 2GB. My only complaint is:

    NVidia only reference model? (sigh)

    I get the reasons. Minimal competition plus overclocking with better cooler beats Titan X hands down (for gaming). Plus, maybe we'll see non-reference later.

    FYI, the EVGA 980 Hybrid got 1600MHz on GPU. That's a fan on main card for VRM's etc and Liquid cooler loop just for GPU with 12cm rad/fan. Even if it "only" got 1300MHz for 980Ti that's still a 30% boost over stock 1000MHz but maybe 1500MHz is actually possible?

    So.. I'll wait a bit longer thanks.
  • turkey3_scratch
    This really seems like a great card! Those frame charts show fantastic improvements over the 980. I was expecting more of a middle-ground between the Titan X and the 980 but it practically matched the Titan X's performance spot-on! All for $375 less.
  • Knicks2012
    So whats the point of having a Titan X now?

    Yea seems like the 980 just lost all relevance. I'm glad to see this though as I was debating whether to get a 980 or not. Guess we just solved that one.
  • Aspiring techie
    Nice! It looks like Nvida is making ultra-high end gaming available to the non-rich folks. All that's left to do is wait for AMD to roll out their cards and see who wins.

    This fills a much needed high end gap. To this point I've still been recommending the R9 295 for the very high end builds. This changes everything and two of these in SLI should finally be able to effectively drive 4K. I don't even consider the silly-priced Titans.
  • corndog1836
    WOW. 780ti is still way up there. thanx for including it again so I can see the progression of things....
  • corndog1836
    just wait for EVGA to make 980ti Classified.. WoooooHooooo!!!!!
  • redgarl
    Your Witcher 3 bench are off. You didn't install the right 15.5 patch and used the leaked one.

    My Crossfire setup with two 290x is averaging at 45FPS. with AA and Hair deactivated at 2160p. Of course, if you activate HairScam, then of course the AMD card crumble...

    The worst is that it is not even good looking.
  • Arabian Knight
    waiting for AMD card . and I hope AMD wins this round. too tired from Nvidia pricing.

    If you put it that way it is a fair point.

    Titan X is for development, no one should have bought it for gaming.

    no it is not and he is a very rude person.

    not all people live in USA and have good salaries.

    People in Romania Graduated from uni for example earn around 500 euro per month only. and is ALL spent on living and eating and clothes and rent , at the end of the month nothing remains.

    in places like India or Ukraine or Africa or Asia is even lower.

    and those work 10 times harder than any one in USA ... but live in a Poor country.

    you are selfish and rude people. very rude !
