PLEASE NOTE THAT THIS GRAPHICS CARD HAS 2 VARIANTS: MAXWELL AND KEPLER. THIS IS THE MAXWELL VARIANT.
GeForce GTX 860M 4GB is a high-end mobile graphics card, based on the 28nm Maxwell GM107 Core.
This variant comes with the extremely energy efficient GM107 Core first seen on GeForce GTX 750/GeForce GTX 750 Ti.
The Full GM107 offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5. Furthermore, the frame buffer was doubled to 4GB though this will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product. .
In terms of performance, the card proves to be faster than the higher positioned GeForce GTX 770M, while it consumes 25% less energy. Therefore, most of today's games can be played at the highest settings and only a few not with 1080p.
This Graphics Card needs to be paired with a decent Quad Core Processor and at least 8GB of RAM.
