Will either of those be cost-feasible, though? Titan X is already clearly using the chips that weren't good enough for the fully enabled Quadro. New process - probably fairly lousy yields on a big chip this early. Can Nvidia afford to release a cheaper card that uses binned chips?
Yeah they should be. Because they'll be coming March next year at the earliest (going off previous examples).
So by then the 16nm process should be far more mature.
