Confirmed by Nvidia: Official GeForce GTX 1070 tech specifications leak

600,000 Get! Here are hard details on the more affordable cousin of the ferocious GTX 1080.

Sure, Nvidia’s US$600 GeForce GTX 1080 is the most badass graphics card ever created, delivering both outrageous power efficiency and obliterating in-game performance. But ever since Nvidia hosted the GTX 10-series reveal two weeks back, the Internet’s been asking one question over and over and over again: “What about the GTX 1070?”

Teased almost in passing alongside the GTX 1080, Nvidia has only publicly said that the GTX 1070 will pack 8GB of GDDR5 RAM and Titan X-level performance for a juicy US$380 (US$450 for the Nvidia Founders Edition).

Until today.

Earlier this morning, alleged specifications for the GTX 1070 began popping up around the web. We’ve confirmed with Nvidia’s Bryan Del Rizzo that the technical details are accurate, and will go live on the GTX 10-series website tomorrow. So here’s an early preview of the card’s high-level details, as first reported by TechPowerUp:

  • 16nm “GP104” silicon, 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
  • 1,600MHz 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

So as expected, this is a cut-down version of the full-fat GP104 GPU found inside the GTX 1080.

With a quarter of the GP104 GPU’s Streaming Multiprocessors disabled in the GTX 1070, the mainstream variant of Pascal definitely won’t punch quite as high as the monstrous GTX 1080. But with the GTX 1080 offering roughly 25 to 30 percent higher in-game performance than the Titan X—as we covered in our GTX 1080 review—it’s very feasible that the GTX 1070 could indeed achieve Titan-level frame rates. That’ll depend on how much the significant clock speed reduction affects performance, however. While the GTX 1080 boosts up to 1733MHz and hits 1607MHz as its baseline, the GTX 1070 hits 1600MHz max.

It’s also worth noting again that the GTX 1070 packs 8GB of traditional GDDR5 memory, rather than the cutting-edge GDDR5X RAM found in the GTX 1080.

All in all, the GTX 1070 looks like it could very well be a worthy successor to the GTX 970, aka the most popular graphics card among Steam users. Expect to see more granular technical details as the GTX 1070’s June 10 release date draws closer.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
