Aorus GTX 1080 Ti Xtreme Edition 11G Review

Every manufacturer seems to have its gamer-oriented brand. For Asus, that's ROG. Gigabyte has the less prolific, but growing Aorus. You can now find motherboards, notebooks, and peripherals under this label. It was only a matter of time before graphics cards joined the fold, too.

Since the design and specifications of Nvidia's Founders Edition cards don't always titillate enthusiasts, companies like Gigabyte feel compelled to bring a little extra to the table. The Aorus GeForce GTX 1080 Ti Xtreme Edition 11G is no exception with its three 100mm fans, generous use of copper, and attention-grabbing lighting.

Since the actual performance of any third-party card depends on the GPU Boost frequency it can sustain, and thus on cooling, power limits, and processor quality, any review that relies on bar charts is little more than a snapshot of a single specimen. That's why we're putting our emphasis on the actual implementation of each model. To that end, a lot of equipment goes into thoroughly documenting a graphics card's behaviors. If you'd like a peek at what goes into such an evaluation, check out our Nvidia GeForce GTX 1080 Ti 11GB Review. It makes for a good baseline on which Gigabyte builds.

The retail card we tested came with an unusually high-quality GPU, which we were able to overclock beyond 2.1 GHz using water-cooling. At default settings, it needed less than 1V. However, since chip quality is a roll of the dice, our voltage and frequency results cannot be considered representative of every sample out there.


The Package, Dimensions & Interfaces

This card is larger than Gigabyte's GeForce GTX 1080 Xtreme Gaming and Aorus' GTX 1080 Xtreme Edition. Further, its backplate and VRM heat sink are entirely new.

Weighing in at a staggering 1.443kg, the Aorus GeForce GTX 1080 Ti Xtreme Edition 11G is beefy, to put it nicely. Its gross length is 29cm from the slot bracket's outer edge to the shroud's back. A 13.5cm height isn't obscene by any means, but a thickness of 5.5cm means you'll need to reserve three expansion slots. Additionally, it requires an extra 0.5cm of clearance on the other side; keep that in mind if you're using a large CPU cooler.

The mix of light metal alloys and some plastics feels cool to the touch, following the company's corporate design.

Up top, you'll find a back-lit Aorus logo and a fan-stop indicator. A pair of eight-pin power connectors is positioned at the end of the board and rotated by 180°.

Peeking into the top and bottom reveals that the cooler's fins are oriented vertically. We also spy an elaborate VRM heat sink that dissipates thermal energy from a number of additional components.

The card's back side reveals five 8mm heat pipes for the right part of the cooler structure. From this angle, a sixth heat pipe (6mm) is hardly visible.

The slot bracket features six display outputs, of which a maximum of four can be used simultaneously in a multi-monitor setup. In addition to one dual-link DVI-D connector, the bracket also hosts two HDMI 2.0b ports and three DisplayPort 1.4-capable interfaces. No doubt, this is a nod to Rift and Vive owners who need at least one HDMI output for their HMD. The rest of the slot plate is dotted with openings for airflow, though they're not functional due to Gigabyte's fin design. There is even a third internal HDMI port, if you'd prefer to hook up your HMD there.

Because there are no suitable video switches with six lanes, Aorus employs two controllers, requiring two separate BIOSes.

BIOS Flash & Aorus Tool

In this review, we're using the current BIOS, version F4, which is based on Nvidia's v. E build. It's a lot more stable than what came before. Thus, we recommend updating to the newest version.

One of the changes Gigabyte implemented was reducing the default mode's power target to 250W, while maintaining the same clock rates. The lower target proved sufficient; additional headroom wasn't needed to sustain its desired frequencies. Overclockers still have access to targets as high as 375W via software, though.

If you're going to update, we suggest using Gigabyte's "VGA@BIOS Utility" for flashing the BIOS. Bear in mind the process gets a little tricky due to the card's dual-BIOS implementation, imposed by the aforementioned video switches. If you want to flash the first (AH) BIOS, you need to use the HDMI2 port. Flashing the second (AD) BIOS necessitates switching to the DVI-D output. Both files are included in the download from Gigabyte's site.

At least for now, we strongly discourage using the special OC mode in Aorus' tool. Instead, overclock through third-party apps like MSI's Afterburner utility.

A GPU-Z screenshot provides the most pertinent technical information, even if the GPU Boost values we observed were much higher than Gigabyte's official specifications.

Test System & Methodology

We explained our test system and methodology in How We Test Graphics Cards. If you want to learn more about the procedures we're using in today's review, have a look at that story.

Since its publication, however, we did beef up our platform and CPU cooling, mostly to rule out the possibility of a processor-imposed bottleneck. This is particularly important given the flagship status of Nvidia's GeForce GTX 1080 Ti.

    It takes 3 slots!? OMG, this is getting ridiculous...
  • FormatC
    2,5 slots. As the most of these fat cards ;)
  • drwho1
    I wait till this cards drop under $300...

    Although by then I might want "that other new one" ....
  • Bloody Chainsaw
    Correction. In the specs chart, the Titan's memory bus is listed as 38-bit. Should be 384.
  • Kevin-M
    At that absurd price point you would think there would be more generosity than the inclusion of one of the most common elements on the planet! Thanks but no thanks, I will remain a smart shopper and wait until the price point comes down to a realistic one!
  • FormatC
    Expensive is relative. Mostly all non-smokers have money enough. It is the question, which priority you set. :)
  • SiggeLund
    Will you be reviewing any of the 1080ti cards with closed loop coolers?
  • FormatC
    If I get one as sample, yes. But closed loop isn't a solution. This are more or less toys.
  • TMRichard
    I must say I think I got a Golden Sample then, my card stays at a stable 2012MHz GPU clock under 65C with fans @ 75% Just waiting on EK to get their block ready so I can add it to my loop!
  • FormatC
    As I wrote in my review - it is a pure lotto. The test sample is running with GPU- und VRM-Waterblock with the AB Extreme and 1.093 Volts at 20°C (chiller) stable 2166 MHz. Other cards neets 1.2 Volts (I have a NO2 BIOS from another card) to crack the 2100 MHz barrier stable. If you buy a card, you get no warranty which GPU quality you get.
  • Sam Hain
    At stock settings,no clocks adjusted, power-limit left at 100% and custom fan curve utilized; fans will run at 60% @50*, 70% @60*, 80% @70*. Mine will boost to 2038 no problem.

    I've never seen the card go above 63* and it is hard to hear the fans.

    EDIT: My case has two front intake fans (one 140mm/one 120mm), an internal 120mm adjustable rail-fan blowing across the top of the Ti, two 120mm exhaust fans and my H105 120's are pulling outside air into the case. This helps a bit with temps.

    I just wish I had one of theese...
  • DerekA_C
    still waiting on vega to start price wars then I will buy
  • DerekA_C
    or I may wait until volta comes since i want dx12 vulkan as the future of gaming and these tend to not do as good in those as amd cards but volta is suppose to change that only one can hope.

    You really sure that Vega can fight with the 1080 Ti customs? The price wars will start (if Vega is coming this year) below the 1080 Ti. The 1080 non-Ti might be cheaper. But wars? AMD need every Cent to survive. If Vega is good, you have to pay for it.

    Nvidia already has all new cards being built will all new ram faster than any other card they have ever made. This will be another Dinosaur in 2 years.

    I seriously doubt it. Sure they've got fast ram in the works, DDR6 specs have already being published this week and someday HBM will be more reality than myth but this vram already offers a lot.

    In twenty years of buying GPU's I've never seen a single card/GPU solution this powerful and holding it's own with the highest resolutions as these OC'd AIB cards. The ram on these are very easily overclockable right out of the box. My Strix is stable at 11.99Ghz for two months now, clock @ 1975-2066mhz, on air and @ 50-65c. Games in 1440p/ultra settings hold 90-130fps and 4k 45-60fps same settings.

    In two years it might show some age but dinosaur it won't be. Prices will probably drop in the next year but there's many articles out there showing how GPU prices are still very relative to price/performance points over 10 years ago. High end cards always cost more.
  • Th3pwn3r
    LOL @ the people complaining about price. People were paying $1500 for Titan's. People were spending THOUSANDS on triple SLI setups. We're getting so much more for our money that it's awesome. When you think PC parts are expensive, I will tell you that I once paid $350 for 2GB of Corsair ram.
  • brucewithatemper
    This thing is aan absolute beast! Thanks for sharing!
  • Kaheel
    Hello,I've got a problem with my 1080 TI Aorus xtreme edition . It's unstable and crashing every 5 to 10 minutes while playing any game.oc mode and game mode,I tried almost everything new driver ,bios even RAM ,PSU1000w
    I've tried it on another PC but still have the same problem.
    It seems a manufacturer problem as i saw while surfing the internet searching for technical solutions. 
    any help?
  • daniel2k
    @KAHEEL the problem is the program that they use. It's unstable because you use the OC mode, try using afterburn from MSI that it's the best everybody from what i've seen that have an aorus said dont use the OC mode or somethin like that maybe is because of that hope i've been useful
  • FormatC
    A few cards of the first batch were not correct selected. I recommend you do use the RMA and as reason use the not working OC-Mode.
