NVIDIA GeForce 820M, codenamed “N14M-GL”, is a mid-range graphics chip, announced in early Q2 of 2014. It is part of the Fermi generation and relies on a GF117 core, constructed through a 28nm process. There are 96 CUDA cores in total.
All of them operate at a base 775MHz and Turbo Mode can increase the frequency by a potential 21%, up to 938MHz, based on the laptop’s cooling facilities.
The chip also has a 64bit bus and DDR3 memory. NVIDIA GeForce 820M supports DirectX 11, Pixel Shader 5.0, Optimus, OpenCL 1.1 and OpenGL 4.3. Memory bandwidth goes up to 14.4GB/sec. Max resolutions (WxH) are 1560×1600 digital and 2048×1536 analog.
