The Nvidia GeForce GTX 1080 Ti has been arguably the most anticipated graphics card of the new year. The 1080 series is Nvidia’s top-end GPU for gamers, and this year's iteration even outpaces the Titan X in several regards.
Priced at $699 or £699 (about AU$930) – the same as the pre-discounted Nvidia GeForce GTX 1080 – this card offers stunning performance that’s often equal to the Titan X. Beyond being Nvidia’s most impressive GPU to date, it’s a showcase of how far the company’s Pascal architecture has come in less than a year.
CUDA cores: 3,584
Texture units: 224
ROP units: 88
Base clock: 1,480MHz
Boost clock: 1,582MHz
Video memory: 11GB GDDR5X
Memory clock: 5,505MHz
Memory data rate: 11Gbps
Form factor: Dual-slot
Power connectors: 1 x 6-pin, 1 x 8-pin
Ports: 3 x DisplayPort 1.4, 1 x HDMI 2.0
The Nvidia GeForce GTX 1080 Ti is packing 3584 CUDA cores, 224 texture units and 88 ROPs. It comes with just a notch less video RAM than the god-like Titan X, but the 1080 Ti’s 11GB complement of GDDR5X VRAM is tuned to a faster 11Gbps – clearly Nvidia is a fan of Spinal Tap – making this Nvidia’s quickest Pascal card.
There’s no question the Nvidia GTX 1080 Ti is a performance beast, running at a base 1480MHz frequency and 1582MHz when boosted.
True, the GTX 1080 boosts to a higher 1,733MHz; however, the Ti model is running with more cores and VRAM, boosting performance in both benchmarks and real-world gaming.
Design and cooling
If you’ve seen one of Nvidia’s self-produced Pascal graphics cards, you’ve seen them all. Externally, the original GeForce GTX 1080 and Nvidia’s latest Ti (or tai as the company pronounces it) card are virtually indistinguishable.
Not that we’re complaining. Nvidia’s design for its Founders Edition cards was a hit when it first debuted and the modern, angular look still appeals. One little change users might notice is the lack of a DVI port; don’t fret though, as the GTX 1080 Ti comes with an adapter you can plug into a DisplayPort.
Getting rid of the DVI port has made more room for a better cooling solution. In fact, Nvidia says its new high airflow thermal solution provides twice the airflow area of the GeForce GTX 1080's cooling system.
Our testing corroborates those claims. Even at a full load, the GTX 1080 Ti stayed at a cooler 75 degrees Celsius while the GTX 1080 peaked at 82 degrees Celsius. Of course, you can push both cards to the edge of 91 degrees Celsius by adjusting the power limiter and overclocking the GPUs.

4K gaming at 60fps with a single graphics card has long been the promised land for gamers, and the Nvidia GTX 1080 Ti is the closest we've come to it. Getting a silky-smooth gaming experience in Ultra HD is highly dependent on which games you play, however.
We were able to achieve frame rates in the 50 to 60 range with games like Battlefield 1 and Doom. That’s not an easy feat - but these are also two of the most optimized games in existence right now.
Likewise, Nvidia released a DirectX 12-optimized Game Ready Driver that helped us run Rise of the Tomb Raider at a solid 40fps, not quite matching the Titan X’s 57fps performance and double the 20fps previously seen on the GTX 1080.
Those are best-case scenarios, and you shouldn’t think the Nvidia GTX 1080 Ti is a bulletproof solution for 4K gaming. Total War: Attila for one thing brought the Titanium-power GPU to its knees as it struggled to render the game at a just-playable 26fps.
Getting to the pure-performance testing 3DMark: FireStrike Ultra benchmark, the GTX 1080 Ti completely demolishes its forebears by a difference of 2,000 to 4,000 points across the board. More impressively, this ultimate GeForce skips ahead of the Titan X too.
The most mind-blowing bit is that the Nvidia GTX 1080 Ti is doing all of this without any overclocking. Nvidia claims the card can be pushed as far as 2GHz, and while we haven’t quite pushed it that far yet we have been able to achieve a stably running system at 1.7-1.8GHz range.
From top to bottom this is Nvidia’s most impressive graphics card to date. It’s remarkably more powerful than the original GTX 1080 while matching the Titan X’s gaming performance. You’re also looking at one of Nvidia’s coolest-running cards with plenty of overclocking potential.
If you’ve been pining for Nvidia’s top GPU, but couldn’t stomach the $1,200 (£1,099, AU$1,599), the Nvidia GTX 1080 Ti looks much more appetizing at $699 or £699 (about AU$930).
