Nvidia’s newest graphics card is — again — its most powerful, its most energy efficient, and its best for next-generation gaming in virtual reality and in Ultra HD resolutions. It’s also surprisingly cheap internationally, and unsurprisingly expensive in Australia. But price aside, if you do happen to pick up a new GTX 1080-based card either from Nvidia or any of its manufacturing partners, you’ll get yourself an extremely powerful and future-proofed card that also serves as a great bellweather for what will be a very important year in graphics technology.
What is It?
- Base Clock: 1607MHz
- Boost Clock: 1733MHz
- Memory Clock: 10.0Gbps
- Memory: 8GB GDDR5X
- Power: 180W, 8pin
The Nvidia GeForce GTX 1080 is the first graphics card released by Big Green on its brand new Pascal microarchitecture. Pascal is the first 16-nanometre graphics card architecture out there, and that represents a significant leap forward in the efficiency of turning electricity into 1s and 0s versus the older 28-nanometre process used in Nvidia’s Kepler and Maxwell cards — you might know them better as the GeForce GTX 6xx, 7xx and 9xx series. The GeForce GTX 1080 is — for now — the flagship card in the line, with a slightly less powerful GTX 1070 also being released a couple of weeks after the 1080.
The GTX 1080 is significantly more efficient than the GTX 980 and GTX 980 Ti and GTX Titan X that it inherits Nvidia’s gaming performance crown from. The chipmaker says it trounces all three of these cards in outright gaming performance, but at the same time it does so while consuming less power. And you can tell that’s true purely through the card’s physical design — it uses a single 8-pin power connector and is rated for 180 Watts of energy usage, where previous models were in the 250 Watt range and used a combo of paired 8- and 6-pin or 8- and 8-pin cables.
While the GTX 1080’s geometrically interesting shroud looks new, its blower design and integrated vapour chamber are effectively the same as the one used on the GTX 980 Ti and Titan X. Third-party cards will have their own (usually superior) cooling solutions. The rear I/O design, too, is the same as 980 Ti with three full-size DisplayPort sockets and one HDMI, as well as a legacy DVI-D connector. The difference is that these ports are all the latest standard — the HDMI, for example, is HDMI 2.0b and supports all the newest gizmos like High Dynamic Range video output and 4K at 60 frames per second.
The GTX 1080 is the first card in Nvidia’s new line-up to use GDDR5X memory, a faster and higher-bandwidth standard that’s a little more expensive than regular GDDR5 but not as expensive as High Bandwidth Memory (HBM), as used in AMD’s new Radeon cards. GDDR5X is anywhere up to two times as fast as GDDR5, and Nvidia has stacked the GTX 1080 with a full 8GB complement of it — this card is intended to be used for the high-res textures and assets of Ultra HD and VR games of this year and next.
What’s it Good At?
In our standardised 1080p benchmarks, the GeForce GTX 1080 monsters through every game thrown at it — it’s more than overkill if you’re looking for consistent 1080p performance above 60 frames per second. It’s a similarly powerful choice for 1440p; with the GTX 1080 being the first in a new generation of graphics cards and also the first of the year alongside AMD’s imminent Radeon refresh — code-named Polaris and Vega — we’re also moving to only running graphics tests both at 1440p and 2160p (4K Ultra HD, 3840×2160 resolution). We’re also going to abandon a few of these games and move to a more modern suite of Rise Of The Tomb Raider, Grand Theft Auto V, DOOM, Project Cars and Battlefield 4 for various DirectX 12, Vulkan and VR testing.
Nvidia GeForce GTX 1080: Average Frame Rates
Far Cry 4 (Ultra): 1080P: 132FPS 1440P: 96FPS 2160P: 49FPS
Battlefield 4 (Ultra): 1080P: 142FPS 1440P: 69FPS 2160P: 61FPS
Crysis 3 (Very High): 1080P: 141FPS 1440P: 69FPS 2160P: 55FPS
Metro: Last Light (Very High): 1080P: 85FPS 1440P: 60FPS 2160P: 46FPS
Tomb Raider (Ultimate): 1080P: 201FPS 1440P: 140FPS 2160P: 58FPS
Almost across the board, this represents a roughly 35 per cent performance improvement on Nvidia’s GeForce GTX 980, and around 20 per cent on the previous generation’s card to beat, the GTX 980 Ti, especially at 1080p and 1440p resolutions. The gap narrows somewhat up at the pointy end of 4K, but consistent average frame rates of 45-60FPS shows that this is just about the first single-card solution that makes 4K games playable at a consistently smooth frame rates. Anecdotally, I can say that it’s still a little short of impressive when it comes to demanding virtual reality resolution and frame rate, but I don’t have the numbers to back that up.
Nvidia has sold its first-run Founder’s Edition cards to its potential buyers on the strength of its craftsmanship and design, and it absolutely is a beautiful piece of technology — as much as a graphics card can be. For something that sits hidden away inside most computer cases, this isn’t a big deal, but if you’re the kind of hardcore gamer that will buy the 1080 to show it off lit up inside your windowed PC case, then you’ll appreciate its chiselled good looks. It certainly feels and looks solid.
The GTX 1080 is partial to a bit of overclocking, too. I’m not a particularly avid overclocker myself — my experience ended with tracing pencil lines on old AMD chips — but the 1080 is the first Pascal card that supports a one-click, card-customised overclocking process through a third-party tool like EVGA’s Precision. The Pascal architecture lets users find the maximum safe clocks at each voltage increment — Nvidia calls this GPU Boost 3.0 — and it’s a very easy way to maximise performance. I hit a maximum full-voltage boost clock of 2.04GHz perfectly easily on my GTX 1080, and from everything I’ve read I’d expect that to be a relatively mainstream result.
What’s it Not Good At?
Nvidia’s claims about performance have, for this particular card and this particular generation of cards, been significantly massaged to make it sound more powerful than it is — which is a pity because it’s already so powerful that it doesn’t need any superfluous marketing on top of that excellent hardware performance. Nvidia says you’ll get three times better performance than the previous generation of GeForce cards, but that 3x figure is only within one specific virtual reality workload — and relies on some new Nvidia tech inside the card that have significantly improved VR processing. So the claims are accurate, just very specific. For regular, everyday gaming, it’s about 30 per cent better than last generation’s GTX 980. Which is plenty.
I’m really, genuinely impressed with the performance that I got out of the Nvidia GeForce GTX 1080. It’s a crazy powerful graphics card, and brings that 30 per cent boost in performance at only 70 per cent of the energy consumption of the previous generation of graphics card. Simply that fact, on paper and in abstract, should be enough to tempt you to purchase the GTX 1080. It’s an impressive feat for Nvidia to pull off.
But then there’s the price tag to consider. Taken in the context of the US$999 ($1600AU £899 in the UK) GTX Titan X that it beats soundly in outright flatscreen gaming performance, and the still-circa $1200 local price of GTX 980 Ti graphics cards available today through All Reputable PC Component Retailers, the GTX 1080 comes with a great price tag (£619 for the Founder's Edition in the UK). But there’s a big Australia Tax, and a big early adopter tax on top of that.
This is shaping up to be a very exciting year in PC graphics, and it’s guaranteed to be one of the best years to upgrade your gaming rig — especially if you’re using Nvidia’s 700-series or AMD’s 7000-series GPUs in your PC already, or an even older card. A card like the GTX 1080 will likely be more expensive than its sticker price if you take into account the fact that you should probably get a new (1440p or 4K) monitor, and you don’t want your old CPU to bottleneck things, and you could really do with a SSD as well…
I’m very interested to see what AMD brings to the table in the next couple of weeks and months. With that said, it’s almost a certainty that Nvidia’s GeForce GTX 1080 will hold the single-card gaming performance crown until the 1080 Ti or the next Titan is announced, and if flagship levels of graphical grunt are what you’re looking for then you won’t be disappointed with the GTX 1080 that you buy.
Our testbed for all our 2016 graphics card benchmarks is a pretty powerful rig — it’s the kind you’d buy if you were a serious gamer, but not necessarily into extreme overclocking and getting the best possible synthetic test scores. It uses a sixth-gen Intel Core i7-6700K processor running at stock 4.0GHz clocks on an Asus Maximus VIII Gene, has 32GB (4x8GB) of Corsair Dominator Platinum DDR4 RAM, and uses a 512GB Samsung 950 Pro M.2 SSD for Windows and game files alike. Cooling is courtesy of a Noctua NH-U12S and everything is housed in a Fractal Design Define Mini.
