What is the Nvidia GeForce GTX 1070?

2016 has been a great year for PC gamers. We’ve seen the arrival of top-notch virtual-reality headsets, such as the HTC Vive and Oculus Rift, plus super-powered VR-focused graphics cards to back them up, such as the Nvidia GeForce GTX 1080.

With all the hype and optimism flooding the PC gaming market, you could be forgiven for overlooking the GTX 1080's less powerful sibling that's on test here. After all, if you’re going to upgrade your rig then the best option is the flagship, right?

But those who dismiss the 1070 will be making a serious mistake. Sharing a common “Pascal” DNA with the 1080, the 1070 is one of the best value-for-money offerings available and should be the first on the list for any PC owner looking to enjoy judder-free 1440p gaming.

Update: Since my original review of the GTX 1070, Nvidia has fleshed out its range of Pascal graphics cards, adding the new, VR-ready GTX 1060 to its roster. Not only is the GTX 1060 ready for whatever your Oculus Rift or HTC Vive throws at it, it also offers a much cheaper route into 1440p gaming. If you’re prepared to make some sacrifices in areas such as anti-aliasing and other fancy effects, it’ll reward you handsomely.

Take a look at our benchmark results on the second page of this review for more information on the differences between the two cards.

Nvidia GeForce GTX 1070 – Specs and technology explained

Nvidia didn’t shy away from making big claims about the 1080’s performance when it unveiled the card earlier this year. The company went so far as to claim it would outperform the £1,000-plus Titan X at certain tasks. Unsurprisingly, the 1070 took a back seat as Nvidia went all-out on 1080 marketing, but many onlookers expected the former to be Nvidia's dark horse this year.

The 1070 has a lot to live up to; its predecessor, the 970 is running on one in 20 gaming PCs according to statistics from Valve's Steam gaming service.

On paper, the card isn’t just a huge improvement on the 970, it can also hold its own against Nvidia’s £550 GTX 980 Ti.

The 1070's use of Nvidia’s Pascal architecture plays a big part here. Pascal is the successor to Nvidia’s previous Maxwell GPU architecture. It improves on Maxwell using a smaller manufacturing process, which reduces the chip’s fabrication nodes from 28 nanometres to 16nm.

The Pascal architecture enables Nvidia to fit more transistors onto a smaller piece of silicon, thus increasing performance while reducing power consumption to a modest 150W.

Thanks to Pascal, Nvidia has been able to cram 1,920 CUDA cores onto the 1070 – the foot soldiers of a GPU that do the majority of the computational-heavy lifting. This is a marked improvement over Nvidia’s GTX 970 card, which houses 1,664 CUDA cores, but still firmly behind the 1080's 2,560.GTX 1070

Pascal also brings to the mix Nvidia’s answer to asynchronous computing. Async compute technology, used by AMD, enables a GPU to work on graphics and computing tasks simultaneously, therefore allowing a card to complete jobs faster. Nvidia’s version of the tech is called "pre-emption", and works slightly differently: it allows the GPU to more intelligently choose which processes to prioritise.

The technology isn’t a big deal right now, since most games still use APIs that don’t support async computing or pre-emption. But with both Vulkan and DirectX 12 growing in use, it will become important in the very near future.

Nvidia’s boosted the 1070’s speed to 1,506MHz, which again is a significant improvement on the 970's 1,050MHz core clock speed; the 1080 clocks in at a slightly higher 1,607MHz.

Watch: Your graphics card questions answered – #AskTrusted

The only possible quibbles you could have with the 1070’s core specs is that it doesn't feature the GDDR5X memory seen on the GTX 1080 and is limited to a two-card SLI configuration.

GDDR5X memory is a new generation of RAM that’s much faster, but it's also more expensive than GDDR5. The tech means the 1080’s 8GB of GDDR5X memory had a clock speed of 10,000MHz.

To me the lack of GDDR5X memory shouldn't be an issue, and when you consider the 1070’s competitive £399 price, you can’t be too disappointed. The card’s 8GB of GDDR5 memory, which features a 256-bit bus for 256GB/sec of memory bandwidth, will meet most regular gamers' needs.

It’s also a marked improvement on the 970, whose lack of memory proved a constant problem. The 970 features a more modest 4GB of GDDR5 memory, only 3.5GB of which was generally usable for the majority of the time. This made 4K gaming on it a pipe dream and 1440p a serious push.

Nvidia is only officially supporting two-way SLI with the GTX 1070. You can get an unlock code to add more cards, but if you do, the three-to-four SLI setup will only work on selected benchmarking applications, such as 3DMark. GTX 1070

Hardcore spec-heads have been up in arms about this, but I believe the complaint is unwarranted. Back in the day, there may have been a reason to connect multiple GPUs, but these days there’s little need for home users. The GTX 1070 and 1080 are both powerhouses, and the fact remains that running multiple GPUs comes with all manner of complications – chief of which is the fact that VR headsets and some game engines don’t like it.

In my mind, it's the VR part of the argument that allows me to forgive the lack of SLI options. This is especially true when you account for the amount of work Nvidia has done with regards to optimising the 1070 for VR. The 1070 has the same Lens Matched Shading, Simultaneous Multi-Projection tech as the 1080.

1440 res, 144hz. Should I get the 1080?

Friday can't come quick enough!!

The 1070 will hover around 60fps on most games at that resolution, not all. A 1080 will certainly do better, but at $150 to $250 more.

Only you can decide, but you should be happy with either card.

I'm looking at the Dell Gaming S2716DG monitor on Amazon for $480. It has 144hz 1440p resolution 1ms response time and G-sync! It should compliment the new card very well.

Is an XB281 not a better choice? Just googled this monitor as I'm tempted by an XB281 and it seems the Dell doesn't offer great contrast levels etc compared to the XB281.

I will be looking forward to AMD's 480, especially, how well OpenCL code performs on the new architecture. I'm positive the 480 will do very well on the graphics aspect but for me computation is the main factor. Nvidia's latest GPU is a monster indeed but from a price/performance perspective; I think AMD are on to a winner.

What? There are no OpenCL benchmarks on the new GCN4 lol

Difficult to say, the only one I can find is double the price of the Dell.

$800 in Australia so not that great a value, and $1200 for 1080

I presume a 1070 will do just fine for the next 4 years on 1440p 60 fps with High setting and 2xAA?

3 years would be fine i'm not sure about 4

Yeah I guess you are right. I know the 1080 is the king, but so is the price.

why would anyone call 400 pounds a competitive privse for a 1070. This card is a mid ranged card it replaces the 97. The 970 came out at 250-260 pounds and the super oced versions 300 ponds so 1070 being 100-170 pounds more that the 970 is very overpriced.

The 480 is a money grab, just a little less than the 970 and around the 960 price, but it gives the performance of around the same as the 970, maybe not even that good. The 10XX series is steps ahead of the 480 and will be for a while.

The head of NVidia should stop lying to us or stop misleading us about the price. My family and I live relatively near where the cards are manufactured & shipped from, and every one of the GTX1070 (&1080) is on Amazon here in the Far East at 50% higher prices than the figures Indicated in the video by the NVidia marketing bod.

Aussie prices are all overpriced the same way as the NVidia cards are all overpriced in Japan, (real near where the cards are manufactured and shipped from).
We are billed from 1300AUD to 2000AUD for the 1080 on Amazon.

1070 is not "mid-range." 1070 is massively faster than a 970.

The mental gymnastics involved in labeling world's second most powerful GPU available as "mid range" must be incredible.
(Pascal TitanX wasn't revealed back when you posted this, and isn't exactly available either.)
