The next 900M series GPUs in NVIDIA’s notebook line-up have been spotted in yet unreleased GeForce 344.77 drivers. The upcoming GPU’s are labeled GTX 965M and N16P-GX respectively, with the latter likely to be 960M.
The 965M (13D9) follows under the same Device ID family as GTX 980M and GTX 970M (13DX). This suggests the 965M could be a further cut down variant of GM204. The other possibility is brand new GM206 silicon, succeeding the aging GK106. N16P-GX, however, is most likely to feature GM206. Considering N15P-GX was the codename for GTX 860M, it is likely N16P-GX ends up as the GTX 960M. The “P” moniker suggests a second rung Performance GPU (GM204), while “E” codenamed cards end up with Enthusiast GM204. However, NVIDIA has been inconsistent with codenames in the past, so things can change.
N16P-GX, irrespective of branding, will succeed GTX 860M, which was one of the first Maxwell GPUs, featuring GM107. Looking to the future, we can expect 860M to show up rebranded in lower-end 900M Series GPUs, or perhaps with refreshed a GM207 chip. While the 800M Series was a stop-gap mix of Kepler and Maxwell (and even Fermi at the very low end), the 900M Series is expected to be the first top-to-bottom line-up dominated by the Maxwell generation.
