Not OP, but my guess would be he meant GTX 1080, Titan & co. I would bet the difference in price in comparison to GTX 1050 doesn't come from increased manufacturing costs.
I think he meant GeForce vs Tesla. The GTX 1080Ti is at the higher end of the GTX line yet it's one of the best in terms of "dollar to performance ratio".
EDIT: even the Titan Xp while being much more expensive than the 1080Ti is still vastly cheaper than Teslas
