The GeForce 920MX is a graphics card by NVIDIA, launched in March 2016. Built on the 28 nm process, and based on the GM108 graphics processor, in its N16V-GMR1-S variant, the card supports DirectX 12.0. Unlike the fully unlocked GeForce 930A, which uses the same GPU but has all 384 shaders enabled, NVIDIA has disabled some shading units on the GeForce 920MX to reach the product's target shader count. It features 256 shading units, 24 texture mapping units and 8 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 965 MHz, which can be boosted up to 993 MHz, memory is running at 900 MHz.
Being a mxm module card, the NVIDIA GeForce 920MX does not require any additional power connector, its power draw is rated at 16 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. GeForce 920MX is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
