Nvidia GTX 1080

Nvidia officially unveiled its latest graphics cards last night—the grand reveal that tooks years of research and billions (with a "b") of dollars to get to. And to the company's credit, the money seems well-spent.
According to Nvidia, its new GTX 1080 card is faster and cheaper than its current top-of-the-line card, the $1,000 Titan X, and it's roughly three times as power-efficient, too. In fact, a single GTX 1080 card is faster than two of its predecessors, Nvidia's GTX 980, running in SLI. And at an MSRP of $600, it only costs $50 more than a typical GTX 980 right now.
Nvidia's GTX 1080 will be the first of its cards to arrive on May 27. Two weeks later, the less-expensive GTX 1070 will likely make its debut with an MSRP of $380. Nvidia didn't release very many details about the latter at its Austin event last night. The GTX 1070 should likely reach just around 72 percent of the performance of the GTX 1080 (a total of 6.5 TFLOPs, which is 2.5 TFLOPs less than the GTX 1080). It'll run GDDR5 memory, not GDDR5X, but we don't know the clock speeds for the cheaper card's memory, nor even how many CUDA cores the card might have or even its base or boost clock speeds.
In other words, we don't know very much about the GTX 1070 at all. While we suspect that it'll launch on June 10, that's actually the date that Nvidia assigns to the card's more expensive "Founders Edition" version, which has a reference design for the card and cooler. The standard version of the card, which costs less, should come out around the same time, but we don't know for sure—and it'll be branded with the trappings of whatever manufacturer ends up making the specific card you purchase.
Both the GTX 1080 and 1070 are Nvidia's first (consumer-grade) graphics cards to be powered by its latest Pascal microarchitecture, which uses 16nm transistors instead of the previous generation's 28-nanometer design. In other words, Nvidia is shrinking its components (again), which allows it to stuff even more onto a single chip—7.2 billion, in the case of the GTX 1080.
To put this all in real-world terms, one of Nvidia's demos from the other evening showed a GTX 1080 running at a clock speed of 2,144Mhz—blisteringly fast—but maintaining a relatively decent temperature of 67 degrees Celsius (air cooled). 
Though Nvidia didn't release the specific name of the GPU powering its new cards, said cards will be using a brand-new SLI setup known as SLI HB, or SLI High Bandwidth. In short, SLI HB doubles the bandwidth the cards have access to, but it'll require to use a new kind of bridge to link them together.
Nvidia didn't just announce new hardware at its presentation, though. If you're looking to take lovelier screenshots and videos in your games, a new Nvidia tool called Ansel will allow you float through your games (if they support Nvidia's SDK) as if you were a large, disembodied, digital observer. Ansel not only supports fancy filters and allows you to tweak the properties of your images while you're shooting them, but it'll also let you capture screenshots at massive resolutions (above 61,000 pixels) and even 360-degree screenshots, if you're hip to the latest virtual reality hardware.
