GeForce GTX 965M quietly joins Nvidia's mobile lineup

Without much (or seemingly any) fanfare, Nvidia has added a third offering to its GeForce GTX 900M-series mobile GPU family. The new GeForce GTX 965M has fewer stream processors and a narrower memory interface than its siblings, but it's clocked a little faster, and it runs its memory at the same speed as the rest of the line.

Model Stream
GeForce GTX 980M 1536 1038 Yes up to 4GB GDDR5 2500 256-bit 160
GeForce GTX 970M 1280 924 Yes up to 3GB GDDR5 2500 192-bit 120
GeForce GTX 965M 1024 944 Yes ? 2500 128-bit 80

Considering the rumor mill has been rife with talk of a desktop GeForce GTX 960 with a 128-bit memory interface and a new GM206 chip, some may see this announcement as an omen of sorts—but they'd be wrong.

We asked Nvidia to tell us more about the GTX 965M, and it turns out this part is based on the same GM204 GPU that powers the rest of the GTX 900M series, along with the desktop GTX 970 and 980. Nvidia simply disabled some of the GM204's functional units to achieve the reduced SP count and narrower memory interface on the GTX 965M. For reference, the fully unlocked GM204 has 2048 stream processors split across four GPCs and a 256-bit memory interface split across four 64-bit memory controllers.

According to Nvidia, the GTX 965M delivers "awesome 1080p gaming in a mobile platform." The company says "many notebook OEMs" already have GTX 965M-powered systems on display at CES this week. Retail availability shouldn't be too far off. (Thanks to TR reader SH SOTN for the tip.)
