We already mentioned that Nvidia is very likely set to release the GeForce GTX 1080 Ti based upon a GTX gaming Celebration (public) event soon.
Nordic hardware now claims this to be the end of March. The website would have gotten its information through Taiwanese videocard makers who let them know the cards would be roughly a month away.
In all likelihood that date would be around 20 and 23 March. The GTX 1080 Ti is powered by a GP102 chip with likely 3328 shader processors enabled. Clock speeds should sit in the 1.5 GHz ranges with boost at say 1.6 Ghz. The memory would be 10 GB on a 384-bit wide memory bus at effective clock rate of 10 GHz. The TDP of the card would be with 250 watts.
Below a chart they compiled.
