Nvidia confirms more GeForce GTX 1070 specifications

Nvidia has fleshed out the specs of the GeForce GTX 1070 graphics card in a new slide, complementing the information we gleaned at the GTX 1080 unveiling event in Austin, Texas. Previously we knew we should expect a headline 6.5 TFLOPS of performance, with GeForce GTX 1070 cards coming packing 8GB of DDR5 RAM. That slide is reproduced directly below.

At up to $320 cheaper than a founders edition GeForce GTX 1080 graphics card many PC enthusiasts and gamers will be looking towards the introduction of the GTX 1070 to provide an almost irresistible bang per buck ratio. Expected to be available starting from $379 next month, we think that users will be able to enjoy up to 80 per cent of the performance of the powerful new GTX 1080 at an agreeable price.

Above you can see the new tech specs illustrative slide from Nvidia. While the slide was 'leaked' it has been subsequently confirmed as genuine by PCWorld. Mashing up the above slide specs with what we already know results in the following bullet point list:

  • 16nm GP104 silicon, with 7.2 billion transistors
  • 1,920 CUDA cores, 15 out of 20 Streaming Multiprocessors enabled on the GP104 silicon
  • 120 TMUs, 64 ROPs
  • 256-bit GDDR5 memory, 8GB
  • 1,683MHz max GPU boost core clock frequency
  • 6.75 TFLOP/s single-precision floating point performance
  • 150W TDP, single 8-pin PCIe power connector
  • 3x DisplayPort 1.4, 1x HDMI 2.0b
  • 2-way SLI with SLI HB bridge support

You can see from the above that the most significant cuts from the GTX 1080, down to the GTX 1070, come with the reduction in CUDA cores from 2560 to 1920. You can also see immediately that there is a lower GPU core boost speed (down from 1733MHz to 1600MHz) but we don't know the regular core clock speed of the GTX 1070. Of course another well known difference in the models is the different graphics memory in use with the GDDR5X in the GTX 1080 providing 320GB/s of bandwidth, beating the GDDR5 in the GTX 1070 which provides 256GB/s of bandwidth. However with the GTX 1070 you are going to save your electricity and a significant chunk of cash in the initial outlay.

As a reminder the Nvidia GeForce GTX 1070 Founders Edition card will become available on 10th June for $449, with the board partner custom design versions being released at $379 or so, a few weeks later.


Nvidia has published a page dedicated to the GeForce GTX 1070 graphics card. There's all the information above, and more, there to look through. One notable spec addition is that we are told that the GeForce GTX 1070 GPU base clock speed is 1506MHz. You may be interested to see how Nvidia compares the GTX 1070 against the previous generation GTX 970 graphics card, as in the example screenshot embedded below...

So (theoretically) around 70% of the performance of a 1080? I reckon that should put it between the 980 and 980 Ti. If we get direct conversion + VAT pricing it'll come in at around £300 for the cheapest cards, which looks to be a fair bit cheaper than the current 980? That feels both good and underwhelming, somehow…!
I have been mulling over an upgrade, but I'll need something more enticing than that if you're right, scary.

It would be really hard to stomach blowing £300 on a new card, irrespective of performance. And if it's not a really significant boost over a 970 then it becomes even less sensible.
Wish AMD would hurry up with polaris 10 - Want to see benchmarks between the two before I pick one of the two up. From rumours the Polaris 10 should be somewhere between a 390 and 390x which should make it close to a 1070 at a guess
“1,600MHz max GPU boost core clock frequency
6.75 TFLOP/s single-precision floating point performance”

1920 * 2 * 1600 = 6.15 TFLOPS.

In addition, it's irregular to use boost clocks to calculate base TFLOPS, but Nvidia seem to be doing it this generation.

Regarding Polaris 10, with one SKU's spec leak of 2304 minimum shaders and 1.266GHz minimum clock, we get 5.8 TFLOPS.

If AMD can get a boost to around 1.4GHz, then they will be beating the 1070 on paper by around 5%.
The usual nVidia trick. Drip feed the performance, with the usual 10/15fps extra over the previous gen, which is to be expected. Man when will companies stop milking customers? Never.

Let the people that JUST HAVE to have the latest buy them releasing cheaper 980/980ti cards to ebay. Buy those instead and overclock if you feel like it. Far more sensible.
