Unlike other mobile GPU launches we can remember, this is not a paper launch, as Nvidia assures us that we will have a chance to see plenty of design wins, including models from some well known manufacturers like Alienware, Acer, ASUS, HP, Lenovo, Razer and others.

As far as we can see from Nvidia's official specifications, both the GTX 960M and the GTX 950M are based on the same 28nm GM107 GPU, the same one behind the Geforce GTX 750 Ti desktop graphics card. Both pack 640 CUDA cores, 128-bit memory interface and the same set of features including Battery Boost, GPU Boost 2.0, Optimus and Adaptive VSync.

The GTX 960M will work at a base clock of 1096MHz with a yet to be revealed GPU Boost clock, which will most likely vary depending on the notebook manufacturer, while the GTX 950M works at 914MHz GPU base clock with undertermined GPU Boost clock. The GTX 960M will ship with 2500MHz clocked GDDR5 memory while the GTX 950M will be available with both 2500MHz clocked GDDR5 memory and 1000MHz clocked DDR3 memory.

As noted, both GPUs should be available immediately in a plenty of notebooks including Alienware 13, Acer V Nitro, HP Omen, ASUS G501, Lenovo Y50, Razer's updated Blade Pro notebook and plenty of MSI's notebooks as well.

Nvidia's site also shows the new Geforce 940M and Geforce 930M GPUs, but fails to share any of details, so we guess we will see those at a later date as well.
