VideoCardz writes NVIDIA's new GeForce 344.77 driver release reveals the existence of the upcoming GeForce GTX 965M and possibly a GeForce GTX 965M.
The driver clearly mentions the GeForce GTX 965M, this card is expected to arrive in a few weeks, and there's also a listing that refers to the NVIDIA N16P-GX. VideoCardz believes this will be the GeForce GTX 960M because the GeForce GTX 860M was codenamed N15P-GX and all Maxwell 900M series GPUs are using the N16 nomenclature.
GeForce GTX 965M is what NVIDIA came up with to satisfy the demand for new mobile cards. We all know notebook manufacturers are always eager to see new cards and series launched in frequent intervals. GeForce GTX 980M and GTX 970M are simply not enough to fill the gap between GTX 800M and GTX 900M series. In fact, only a small portion of notebook sales are based on these two chips. Usually it is the mid-range segment (with cards like x50M or x60M) series that is the most popular and most affordable for end user.
The listing below is taken from GeForce 344.77 drivers. You can see five new entries, from which three are clearly stating the codename of new card, and then there’s N16P-GX. Here I should tell you that GeForce GTX 860M processor was codenamed N15P-GX and Maxwell 900M series are using N16 nomenclature. So, N16P-GX could simply be GTX 960M.
