The NVIDIA GeForce GTX 1080 Ti Review

Author: Ryan Shrout
Manufacturer: NVIDIA

3DMark, Unigine Heaven and Overclocking

Let's look at a set of tests from more standard benchmarks like Unigine Heaven and the new 3DMark benchmark. 

I consider these tests to be somewhat of a "best case" for all the cards in our comparison.  We aren't using our frame capture system, we aren't measuring frame latency, nothing like that; I think this should give you an idea of graphics performance if each vendor had the best result for each game.

In 3DMark the GeForce GTX 1080 Ti is a couple of points faster than the Titan X, as expected, which is only made impressive when you consider the launch price points of those two products ($1200 vs $700).

Under Unigine Heaven, the same result is demonstrated. The GTX 1080 Ti is slightly ahead of the Titan X but is 44% faster than the GTX 1080!

Overclocking Results

I didn't have much time to spend tweaking the new GTX 1080 Ti but I was able to use the latest EVGA Precision X software to push our sample to its limits. Overclocking and the process of doing it remains unchanged for the GTX 1080 Ti compared to previous products. We adjusted the power target to 120% and the TDP limit to 90C and started ramping up the clock speed offset to see how high we could get while remaining stable.

This screenshot was from early in our stable overclock settings and as the temperature on the GPU rises the clock speed settles in around the 1960 MHz mark. I was able to push our GeForce GTX 1080 Ti to a +150 MHz offset which bumps the base clock from 1481 MHz to 1631 MHz and the "typical" Boost clock to 1732 MHz. In practice, our long term gaming clock speeds were noticeably higher than that as you'll see below.

Clock Speed Consistency

Looping Unigine Heaven for 10 minutes to warm up the GPU for testing, I used GPU-Z to capture the clock speed and temperature of the GPU in real time to see how consistent the clock speeds were at both stock and overclocked settings.

Clock speed stability of Pascal at stock settings continues to be lower than I would expect from a company in its position. NVIDIA is slightly aggressive with target clock speeds and voltages ath the rated power targets, and that results in the variance that you see here.

Once overclocked, things are not only faster, but considerably more consistent. This is likely because we have increased the power limit.

With everything at stock, the average frequency in this test over a long period was 1725 MHz, about 65 MHz faster than the stock settings of our Titan X last year. When overclocked with a +150 MHz offset and increased power target, the average bumps all the way to 1963 MHz! This is short of the 2.0 GHz clock rate that NVIDIA showed at its launch event, but I have a sneaking feeling they were running at 100% fan speeds in those demos. All considered, this is an impressive result for the new flagship GeForce product.

Small remark on 11 page (Detailed Power Consumption Testing):

Last Light testing at 4K with the Titan X running at a +150 MHz offset (should be 1080 Ti, instead of Titan X).

Other than that - thanks for review.

Saw that too, copy pasta!

interesting power draw from 6-pin & any slow down once we hit peak of 11 GB VRAM?

weird no DOOM, For Honor, Sniper Elite 4 etc benchmark?

March 9, 2017 | 02:36 PM - Posted by Anonymous (not verified)

Doom isn't much of a stress test for anything, I think thats been demonstrated very well by many testing outlets. For Honor and Sniper Elite 4 are pretty damn new, hard to castigate them for not using them

Actually running with Vulcan is good for testing CPU OC stability.

March 9, 2017 | 09:26 AM - Posted by Anonymous (not verified)

2% faster then GTX1080 in Grand Theft Auto V and Gears of War at 1440p.


March 9, 2017 | 11:53 AM - Posted by slizzo

Those two titles are heavily CPU dependent.

Gears of War isn't

Unreal engine isn't cpu dependant

Thanks for the 1400p 980ti benchmark comparisons for those of us thinking of upgrading from that gpu. Looks like a pretty compelling upgrade.

My one question is the reference PCB layout. Is it identical to Titan X pascal? I like to watercool my GPUs to get the most out of them

March 9, 2017 | 09:59 AM - Posted by Jann5s

yes, it is the same PCB, see the pictures here

250 amps? I'd like to see that power supply!

March 9, 2017 | 10:51 AM - Posted by Anonymous (not verified)

At 3V, 5V, 12V... to name a few! :)

March 9, 2017 | 12:19 PM - Posted by Anonymousmouse (not verified)

Hopefully, it is at 1V or below:) It was mentioned in the launch live stream too, there must be a mix up somewhere.

"the NVIDIA GeForce GTX 1080 Ti is going to be selling for $699 starting today from both NVIDIA and it's partners"

But.. but.. it's not selling today anywhere..

March 9, 2017 | 11:54 AM - Posted by slizzo

Yeah, looks like NDA date was today, actual launch is tomorrow.

March 9, 2017 | 01:01 PM - Posted by Anonymous (not verified)

Any word on the 980ti step up to 1080ti?

March 9, 2017 | 01:04 PM - Posted by Anonymous (not verified)

A bigger chip off the GP 102 block, so more performance through more resources. It will be intresting to see what AMD's Vega will offer in performance with all of Vega's new features that are new to the Vega micro-arch relative to the Ti's more amounts of the same with some slightly higher clocks. that $699 price point will not be too difficult for AMD to beat and Vega will have that NCU, HBCC, and other all new features to take into account. So it's the Pascal refresh versus Vega's new features for AMD's latest Flagship offering when Vega is released 2Q of 2017.

AMD does have its more of the same in the mainstream also with the RX 500 series Polaris refresh offerings in April but then Vega will be following. So hopefully by the summer Vega will be here.

I hope that the games are being tuned for Vega in advance unlike some of the games that were/are still not tuned for Ryzen or Ryzen's extra cores for the affordable prices.

You realize that by the time Vega is out (may), we will be looking at preliminary Volta information, right?

AMD missed this generation entirely on the high-end.

March 9, 2017 | 03:19 PM - Posted by Anonymous (not verified)

Good more Volta news to force AMD to get its Navi to market on time! But with Zen/Ryzen and Zen/Naples making some mad revenues for AMD there will be no more excuses for AMD to be late with any flagship SKUs! So the competition moves from the two Ps in the mainstream market to the two Vs in the Flagship market. AMD does not have a flagship P SKU but some dual RX 480 prices deals will be had by some when the RX 500 series P refresh get here for AMD’s mainstream P SKUs along with that V flagship from AMD shortly after.

That Ps and Vs competition will lead to some N and whatever comes after competition as always.

Vega is coming to desktop in the next few months. Desktop Volta is now 1H next year. So at minimum it will be *at least* six months behind Vega, and possibly as much as a year.

Also, AMD will be launching Navi next year. So it won't be Vega that Volta finds itself up against.

Hate to break it to you, but it's AMD who are going to leap frog 'Paxwell' with Vega this year, and unless Volta is something really special, Navi will keep them ahead.

I'm not really sure how you managed to get things *completely* the wrong way round, but trust me, you have.

march 2017. amd gives out "vega" tshirts. nvidia releases a new enthusiast card. and drops the price on another. #gofigure

you have an error in the summary, "Whether or not they can deliver on those promises has yet to be proven.", should say 'deliver on any promises has never been proven'.

Still very upset about Rysen.

PC Master Race, lets see those breath of wild & horizon zero dawn benches. LOL reviews 2 week's before launch suckas

You have a knack for scrutiny. Prepositions aren't sentunzez. Phreiz is 4 needing, dog cat barf, pooped em' XD

Seems there is a typo in OC page:

'NVIDIA is slightly aggressive with target clock speeds and voltages ath the rated power targets, and that results in the variance that you see here.'

I think you should do an article on just how much of a lie TDP figures can be.

250W part? Might spike to 20% higher than that rating.

I think this is something that has real consequences. For supercomputers and other systems that have to last and be run at full load with minimal amounts of failures, this is unacceptable because it shortens the bathtub curve somewhat unpredictably.

Consumer GPUs with boost features are made to squeeze every last bit of performance out of them, rather than last long and be reliable. Hopefully theboard makers compensate, and hopefully their EDA, electromigration simulations and emulation when designing the chips treat the TDP as a complete lie as well.

Power virus games with shitty ScaleformUI menus could very well have a gpu like this sitting above its TDP long enough to probably cause some electromigration. Its really no wonder that larger GPU VRMs are a common failure.

March 9, 2017 | 04:28 PM - Posted by superj (not verified)

I think the key to TDP is that it is THERMAL DESIGN POWER. Not Total Input Power. As long as the short term average power stays below the rated TDP, then substantial brief spikes above the TDP are ok since the thermal cooling capability is buffered by the thermal mass and dissipation power of the cooler.

Why not Doom test?

108% faster than Fury's in AMD sponsored Hitman 4k. Wow!!!!!

37% better than 1080 in GTA5 4k.

26% faster than 1080 Gears of War 4k.

Performance in 1440 may be the result of both ti and 1080 hitting engine limits not that ti is only 2% faster.

This card is designed for 4k isn't this what AMD users always bragging on.

Anyways I'm looking for a great 4k card and this looks like a winner.

Good review PCPer.

great review.

WHY in your testing results do you not show any results for multiple monitors. With all the connectors on the GPU, Why don't you do any testing using them ?

March 9, 2017 | 05:27 PM - Posted by Jeremy Hellstrom

FCAT incompatibility unfortunately.  We are working on it with vendors, so hopefully we will be able to do this soon as we do want to provide that info in reviews.

I am very envious, looks amazing

Seems to be the best card ATM! For quality and price, gtx 1080 ti FTW!

March 9, 2017 | 07:46 PM - Posted by ChuckyDiBi (not verified)

That power draw is much smarter when it come to repartition than the mess that was stock RX480 at launch. Still, I'd wait for a dual 8pin version from OEM!

March 10, 2017 | 02:13 AM - Posted by serpico (not verified)

I'm curious how you measure power through PCI-E. Measuring voltage is easy enough, do you use a precision resistor and op-amp to measure the current?

March 12, 2017 | 06:44 PM - Posted by crackshot91 (not verified)

Hey Ryan, just wondering if you could share the exact settings you used for the unigine heaven bench? It says 1440p Ultra, but what about tessellation (I imagine that's maxed out, of course) or more importantly, antialiasing? Only wondering because compared to your 980 score, mine is a few fps lower with 8xAA, though my card is heavily OC'd and scores significantly higher in 3DMark. Just trying to get a perfect-as-possible comparison :)

Any word on wether that display port adapter is active or passive?

March 14, 2017 | 08:02 AM - Posted by Ninjawithagun

Get a new monitor that has DisplayPort 1.2 or higher. Problem solved. Why would you waste money buying an adapter for an older, inferior monitor?

March 16, 2017 | 11:41 AM - Posted by An extremely concerned reader (not verified)

I have 4 displays, I'd like to use all of them and am wondering whether I'd need to buy another adapter or use the one supplied with the card. What kind of pleb only runs one display? Do you even know how to PC Master Race?

March 14, 2017 | 08:01 AM - Posted by Ninjawithagun

Meh, my Titan X performs a bit better as it will hit 2100Mhz on the GPU. The only real advantage here is the price point. For me, it's a 'no thanks'. I'll wait for Volta to be released this fall ;-)

April 24, 2018 | 11:03 PM - Posted by ment1 (not verified)

I’m running a 8700K at 4.9 ghz + 16 gig ram + ASUS gtx 1080ti Turbo (OC) + 2560x1440 res

Same settings as the review

In game benchmark always stays at around 90 FPS and no more

Any idea why ?
