TweakTown picked up rumors that the Pascal 2.0 release will include more GPUs based on the GP102 core, including cheaper versions of the Titan X and GTX 1080 video cards.
With exception of the entry-level parts, the entire Pascal 2.0 lineup is expected to feature GDDR5X memory. The source also claims these parts will be made on a 14nm FinFET process from Samsung, a rumor that started surfacing a couple of weeks ago.
This rumor is in contrast with previous rumors about a 16nm Volta launch in 2017 so take it with a grain of salt.
