The GeForce 820A was a mobile graphics chip by NVIDIA, launched on March 17th, 2014. Built on the 28 nm process, and based on the GF117 graphics processor, in its N15V-GM 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 GF117 graphics processor is an average sized chip with a die area of 116 mm² and 585 million transistors. It features 96 shading units, 16 texture mapping units, and 8 ROPs. NVIDIA has paired 1,024 MB DDR3 memory with the GeForce 820A, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 625 MHz, memory is running at 1001 MHz.
Its power draw is rated at 15 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 820A is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
