Yeah that is gm107 version of the 940MX(512 shaders, gm108 has 384 max) with 1GB GDDR5 on 64bit memory interface(ahh they cutted the memory interface to half on gm107 chip for 940mx).
I would say VRAM amount is fine for that slow gpu. It's better to have 1GB gddr5 than 2GB of ddr3. +Being gm107 you have nvenc video encoder, so shadowplay(probably not that usefull) and gpu encoding should work on it.
