The GeForce 940M is a graphics card by NVIDIA, launched in March 2015. Built on the 28 nm process, and based on the GM107 graphics processor, in its N16S-GT1-KB-B variant, the card supports DirectX 12.0. The GM107 graphics processor is an average sized chip with a die area of 148 mm² and 1,870 million transistors. Unlike the fully unlocked GeForce GTX 750 Ti, which uses the same GPU but has all 640 shaders enabled, NVIDIA has disabled some shading units on the GeForce 940M to reach the product's target shader count. It features 512 shading units, 32 texture mapping units and 16 ROPs. NVIDIA has placed 2,048 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 1020 MHz, which can be boosted up to 1098 MHz, memory is running at 900 MHz.
Being a mxm module card, its power draw is rated at 75 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it.
