Inno3D GeForce GTX 1080 Ti iChill X3

GeForce GTX 1080 Ti iChill X3 boxNvidia partners may each have their 1080 Ti model, but Inno3D is looking to best them all with its own version of the Nvidia GeForce GTX 1080 Ti iChill X3.

For us, even the name is enough to whet the appetite. And it should be too: featuring the most powerful Pascal-driven GPU Nvidia has to offer, this card delivers heftier specs than we’ve seen before.

That means it will handle 4K gaming VR, and most things you’d want to throw at it. But to what level? Looking towards the most powerful 1080 Ti we’ve seen – the Asus’ 1080Ti ROG Strix OC – this may win out. On price too, as the GTX 1080 Ti iChill X3 is available for under £700.


  • 3,584 Stream Processors
  • 1,607MHz Core Clock
  • 11GB 352-bit GDDR5X
  • 1,426MHz Memory Clock
  • PCI Express 3.0
  • DisplayPort Ready: 1.4
  • Max Supported Resolution: 7,680 x 4,320
  • 1 x DVI-D, 1 x HDMI 2.0b, 3 x DisplayPort 1.4GeForce GTX 1080 Ti iChill X3 front

We necessarily need to put it this card against the 1080 Ti ROG Strix OC, because that’s the beefiest card we’ve tested. Similarly, the iChill has 3,584 stream processors, but in terms of clock speeds Inno3D has raised the bar.

While the Asus core clock achieves an approximate 8% gain on the 1080 Ti base specs, Inno3D’s is closer to 9%. That means a huge core clock of 1,607MHz in this card, boosted up to an eye-watering 1721MHz – a feast for the performance hungry.GeForce GTX 1080 Ti iChill X3 rear

Turning to the memory, this card boasts NVidia’s newest – first-generation GDDR5X, and there’s 11GB clocked at a massive 1,426MHz. It’s around 400MHz more than NVidia’s specs, and over 300MHz more than Asus’ card.

That means this part is able to deliver over 500GB/s memory bandwidth (502GB/s to be precise) across a 352-bit memory bus. Those specs, delivered by virtue of a 8+6-pin design, should be power enough for any enthusiast. One things cleat, Inno3D wants to make a mark.

Design – Inno3D Nvidia GeForce GTX 1080 Ti iChill X3

With so much power on hand, the GeForce GTX 1080 Ti iChill X3 needs a design to match – not necessarily the striking military styling it’s given in, but some serious cooling and card support. For the first of those duties, Inno3D has summoned it’s iChill X3 cooling solution.

Beneath the triple fans, iChill X3 features a PDCS (power direct cooling solution), including a sizable memory heatsink, GPU heatsink and a solid heatpipe/aluminium fins combination. This solution isn’t the most comprehensive we’ve seen, but certanily shouldn’t leave the card in danger.

Other features of note include a ‘0dB’ fan full-stop mode, and an iChill logo-shaped LED indicator showing the level your card’s working at (blue = low power, red = ‘Full Gear’ gaming, green = low power gaming).

All of this is fixed on to Inno3D’s full-length Herculez Backplate – a necessity on a 2.5 slot card which is a little over 30cm in length. However, one thing Inno3D has eschewed is integrated PWM-equipped fan headers. So if you’re keen on extra case cooling support, you’re out of luck.

Performance – Inno3D Nvidia GeForce GTX 1080 Ti iChill X3

With the specs this card has we’d expect some really strong performance. Handily we’ve got it, and the GeForce GTX 1080 Ti iChill X3 delivered a score of 7,066 in 3D Mark Ultra.

This test is designed specifically to test the 4K capabilities of a card, and it’s the highest score we’ve seen. More than the ROG Strix 1080 Ti, and threatening to leave most Pascal-powered graphics solutions a little lacking.

If our 3D Mark score hints at high performance, our gaming tests confirm it. Running in 4K at Ultra settings, the card powered through Battlefield 1, with a 77fps average. Fallout 4 and Witcher 3 scores were lower, but produced effortless performance with averages in the high 50s.

The one thing we expected, and is noticeable, is the increase in heat that the power and performance of this card brings with it. Running through Unigine Valley at 4K resolution, the peak temperature topped out at 82 degrees. Idling was fine at 33c, but that 82c is around ten degrees higher than we’d like to see it. So it’s more than a little warm.

Nvidia rates the max temp of the 1080 Ti is 91c, so 82 isn’t as far away as we’d like. Having said that, we’re not sure almost ten degrees below that limit is likely to cause significant long-term issues. Solid case cooling is recommended for anyone concerned by overall system temps though.

Conclusion – Inno3D Nvidia GeForce GTX 1080 Ti iChill X3

We recently called the Asus ROG Strix Nvidia GeForce 1080 Ti OC a ‘beast’. That has to make the Inno3D Nvidia GeForce GTX 1080 Ti iChill X3 even more beastly. Able to deliver faultless 4K gameplay and VR, Inno3D has taken the Nvidia 1080 Ti specs and tweaked them to the extreme.

What we have here is a beast in all senses. This is a physically imposing, game-thrasher of a card, and it looks as business-like as its benchmark scores proves it to be The highest performing 1080 Ti card we’ve yet seen, to spot it available for less than lesser performing cards is surprising. There’s a caveat here though. While this card is a monster, the heat it generates may turn some away. The physical size of the part is also worthy of consideration, but that’s not uncommon at this level of performance.

Ultimately what it comes down to is the balance of need and want. Few may need this card, but its huge performance may be tempting. We can see why, and especially at the prices we’ve seen it being offered at. The included mouse mat wouldn’t really sway us, but if we wanted massive performance whatever the trade-off then we’d look here.
