The GeForce 820M is a mobile graphics chip by NVIDIA, launched on March 21st, 2015. Built on the 28 nm process, and based on the GK107 graphics processor, 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 GK107 graphics processor is an average sized chip with a die area of 118 mm² and 1,270 million transistors. It features 384 shading units, 32 texture mapping units, and 16 ROPs. NVIDIA has paired 2,048 MB DDR3 memory with the GeForce 820M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 810 MHz, memory is running at 901 MHz.
Being a mxm module card, 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 820M is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
