The GeForce GTX 850M was a mobile graphics chip by NVIDIA, launched on March 12th, 2014. Built on the 28 nm process, and based on the GM107 graphics processor, in its N15P-GT-A1 variant, the chip supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GM107 graphics processor is an average sized chip with a die area of 148 mm² and 1,870 million transistors. It features 640 shading units, 40 texture mapping units, and 16 ROPs. NVIDIA has paired 2,048 MB DDR3 memory with the GeForce GTX 850M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 902 MHz, memory is running at 1001 MHz.
Its power draw is rated at 45 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. GeForce GTX 850M is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
