The Nvidia GTX 850M GDDR5 is a 800 series’ mid-top midrange gaming GPU, based on the Nvidia Maxwell (I) architecture and the GM107 core and using GDDR5 VRAM. At its time, the GTX 850M GDDR5 could be found in laptops for as low as $700-$800 with a typical price of around $800-$1000. There is a second version of the GTX 850M with DDR3 VRAM which delivers considerably lower gaming performance (core is the same, but memory bandwidth is “choking” it).
Gaming performance is adequate for medium-high graphics settings @ 1080p. Compared to the Pascal current offerings (2018), performance is about a little higher than the entry level MX150 in heavy 3D games and considerably lower than the GTX 1050 and 1050 Ti. So, the GPU is not cost effective as of the release of the Pascal architecture (or later), that’s besides requiring considerably higher power to operate.
- GTX 850M DDR3
- GTX 850M GDDR5
- GTX 960M
The GDDR5 version is the same as the GTX 860M in practice, but with around 10-15% lower maximal core clocks and can easily be overclocked to the 860M levels.
Both these GPUs were rebranded as GTX 950M and GTX 960M.
