Graphics Performance

The GeForce 845M scores 1,487 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 (2014−2017) architecture (codename: GM108), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 384 shader units (the primary compute units for rendering pixels), 32 TMUs (texture mapping units), and 16 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 0.9032 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1176 MHz from a base of 1071 MHz.
