I have had confirmation from DVDFab developers that even though the GTX1070Ti/GTX1080 has 2x NVENC engines, DVDFab will only use a single engine.
On that basis, a GTX1080 is little/no faster than a GTX1050Ti when encoding as they both will only use 1x NVENC CUDA engine.

That is correct, you asked how many engines it had, so I told you. In relation to Fab , Fab will only use one of the engines.
