Introducing The GeForce GTX 1070
The GeForce GTX 1070’s official reference specifications were revealed a few days after NVIDIA's event, but we’re now able to give you the full scoop. We’ve put a GeForce GTX 1070 Founder’s Edition through its paces and have all of the juicy details laid out on the pages ahead. First up though, we’ve got some specs to get out of the way...

The GeForce GTX 1070 is based on the same GP104 GPU used on the GeForce GTX 1080, and as such, the GeForce GTX 1070 supports all of the new features that NVIDIA’s Pascal architecture enables, including Simultaneous Multi-Projection, more advanced memory compression, GPU Boost 3.0, and others. For more detailed information regarding Pascal, and the changes / enhancements NVIDIA introduced with the architecture, we strongly suggested checking out our GeForce GTX 1080 launch article. We covered Pascal’s new technologies in that piece and won’t be doing so again here.
The GP104 GPU used on the GeForce GTX 1070, however, is scaled down somewhat. Specifically, one of its GPCs (Graphics Processing Clusters) has been disabled, which results in a total of 1920 active CUDA cores, versus the 1080’s 2560, and 120 texture units – the GTX 1080 has 160. The GeForce GTX 1070 also has slightly lower clocks – 1607MHz base and 1733MHz boost, and the 1070 employs standard GDDR5 memory, whereas the 1080 employs more advanced GDDR5X. It's still got a 256-bit interface, though.
All told, the GeForce GTX 1070 ends up with a lower peak fillrate and less available memory bandwidth, but the Pascal architecture and its relatively high clocks still give the card plenty of oomph, as you’ll see in a just a bit. On the plus side, the 1070’s TDP is down to only 150 watts and the card requires only a single supplemental 8-pin power feed.
The GeForce GTX 1070 Founder’s Edition also features a die cast aluminum body which is machine finished and heat treated for additional strength and rigidity. The top edge of the card has NVIDIA’s signature, lighted "GeForce GTX" logo that's adorned cards from the last few generations as well.
