A lot of people expected NVIDIA would introduce the GeForce GTX 1080 Ti during the company's keynote at CES 2017. Obviously, that didn't happen but there are still strong indications that this product is under development.
Last month there was a rumor that we might see a GeForce GTX 1080 Ti launch in March and now Nordic Hardware claims sources at Taiwanese graphics card makers confirmed this. NVIDIA is reportedly planning to launch the model towards the end of March, with March 20-23 being the most likely timeframe.
The source claims cards are in production so if this is true there's a good chance NVIDIA may use its GeForce GTX Gaming Celebration event on February 28 to show off the GTX 1080 Ti to the public.
The long-awaited GeForce GTX 1080 Ti is believed to be based on the 16nm FinFET GP102 GPU with 3328 CUDA cores. Rumored specifications point to a 1503MHz base frequency 1623MHz Boost, 10GB memory and a 250W TDP. The card has fewer CUDA cores than the Pascal-based Titan X but has higher base and Boost frequencies.
Nordic Hardware mentions its sources are quiet about the AMD Vega, they believe the card may be launched towards the end of May or early June.
