Graphics Performance
The GeForce GT 820M scores 542 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Entry Level tier as a Legacy generation graphics card. It is built on the Maxwell 2.0 (2014−2019) architecture (codename: GM204), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 1536 shader units (the primary compute units for rendering pixels), 96 TMUs (texture mapping units), and 64 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 1.659 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1127 MHz from a base of 1038 MHz.
