Nvidia made the GeForce GTX 1070 and GTX 1080 official tonight at the Dreamhack festival in Austin, TX. As expected, these graphics cards use a Pascal GPU fabricated on TSMC's 16-nm FinFET process. The GTX 1080 uses GDDR5X RAM, while the GTX 1070 uses GDDR5. The GTX 1070 and GTX 1080 cards themselves look almost exactly like the variety of cooler shrouds leaked in recent days.
The GTX 1080 promises 9TFLOPS of single-precision performance, and it comes with 8GB of GDDR5X RAM. That card will be available May 27 for a suggested price of $599, or $699 for the "Founders Edition" card. The Pascal GPU on this card includes 2560 stream processors clocked at a boost speed of 1733MHz.
The GTX 1070 promises 6.5TFLOPS of single-precision performance. It comes with 8GB of GDDR5 RAM, and it'll carry a suggested price of $379 when it hits store shelves on June 10. Like the GTX 1080, the GTX 1070 will also come in a "Founders Edition" for $449.

Nvidia CEO Jen-Hsun Huang made some startling performance claims regarding its new graphics cards. Huang said the GTX 1080 will be twice as fast as a single Titan X—all while using a little more power than a single GTX 980. The GTX 1070 is purportedly "faster than a Titan X."
To demonstrate Pascal's overclocking prowess the company ran a Paragon demo on a GTX 1080 card running at a whopping 2116MHz with an air cooler. The chip only hit 67° C or so under load.
