The AMD 7000 series in the XBox One and PS4 is about the equivalent of a GeForce 580. There are some console based optimizations that may make it faster than an equivalent PC 580 though, which is why W3 requires a 660. The 660 and 660 Ti are close enough performance-wise that the game is fine on either. Also while the Ti is slower on total performance (by a tiny amount), it has quite a few more shaders and texure mapping units (about 30-33% faster). Incidentally, I'm playing Witcher 3 on a 660 Ti and with nVidia optimized settings have not seen any issues. Honestly, I'm guessing the game is actually playable on even lower end cards but you may have framerate drops below 30FPS and that wasn't acceptable to CD Projekt Red.
750s are often a bit slower than the 660s, however, due to lack of cores (especially on the low end), but I'm guessing the game would still be playable, as the AMD equivalent on the PS4 and XOne is 1152 cores and unless something has changed recently, one nVidia core generally performs about the same speed as 2 AMD cores (from what I recall, AMD's cores aren't fully general purpose for texture and pixel operations, but are for general purpose, which is why AMD is often preferred for stuff like bitcoin mining and password cracking).
