The NVIDIA GTX 1080 and GTX 1070 are now official. The company has announced the GeForce 1000 series at an event in Austin, Texas, where the GTX 1080 will be offered before the month ends, while the cheaper GTX 1070 will be available by June.

The company announced their two Pascal architecture-based video cards that have boosted overall performance, better memory bandwidth and is more power-efficient that the company's previous offering. NVIDIA claims that their new GPU will be twice more powerful in virtual reality workload compared to their older GeForce Titan X.

The GTX 1080 is equipped with 2560 CUDA cores (the GTX 980 contains 2048 CUDA cores) and is clocked at 1,607 MHz, which can be boosted to 1,733 MHz. Gamers who are planning to purchase one would be happy to know that the two GPU is overclockable with the new GPU Boost 3.0.

Jeff Fisher, senior vice president of NVIDIA's PC business said, "The PC is the world's favorite gaming platform, and our new Pascal GPU architecture will take it to new heights."

Fisher added, "Our first Pascal gaming GPU, the GeForce GTX 1080, enables incredible realism in gaming and deeply immersive VR experiences, with dramatically improved performance and efficiency. It's the most powerful gaming GPU ever built, and some of our finest work."

The premium model also comes with an 8 GB GDDR5X memory with a 256-bit bus that offers 10 GB/s of memory clock and 320 GB/s memory bandwidth. Overall, it offers around 25 percent improvement against Titan X, and as much as 65 percent against the GTX 980 model.

No technical information is available yet for the new GTX 1070 except that it is using the older GDDR5 memory.

Booth cards use the same 16nm FinFET process and comprise 7.2 billion-transistor count.

The NVIDIA GeForce GTX 1080 "Founders Edition" will be available on May 27 for US$699, while custom board from OEM is expected at US$599.

The NVIDIA GeForce GTX 1070 "Founders Edition" will be available on June 10 for US$449 and OEM models will start at US$379.
