Nvidia has officially taken the wraps off two consumer-grade Pascal graphics cards, the GeForce GTX 1070 and GTX 1080, claiming to beat the performance of the company's earlier Titan X at half the price.
Unveiled at a 2AM showcase event on Saturday morning, Nvidia's latest graphics cards are built with Ultra HD and virtual reality gaming in mind. Both models feature the same Pascal graphics processing unit (GPU): the GP104, boasting 2,560 CUDA cores. In the top-end GTX 1080, this is linked to 8GB of GDDR5X memory with a claimed 320GB/s of throughput via a 256-bit interface; the 1070, meanwhile, opts for slower GDDR5 memory with an as-yet unconfirmed throughput. Nvidia hasn't clarified whether the clock speeds - 1,607MHz stock boosting to 1,733MHz - are the same between the two cards, but has stated that the GTX 1080 can throw out nine teraflops of compute performance to the GTX 1070's 6.5 teraflops.
For the GTX 1080, the only model for which full launch specifications are publicly available, Nvidia is claiming some impressive figures: the card is claimed to draw just 180W, run happily from a system with a 500W power supply, and use just a single eight-pin supplementary power connector. The reference design board is 111.2mm long, and takes up two slots with the standard cooler design.
At the same event Nvidia introduced a new in-game photography feature dubbed Ansel, named for noted photographer Ansel Adams. When supported by a game - something developers need to explicitly code in - Ansel allows a game to be frozen and the camera positioned freely. Shots can also be captured in 360 degrees, for later viewing on virtual reality headsets or gyroscope-equipped smartphones and tablets.
Nvidia has indicated US pricing of $379 for the GTX 1070 and $599 for the GTX 1080, with UK pricing expected to be announced closer to the 27th of May launch date of the latter card. More information is available on Nvidia's website
