Graphics Performance

The GeForce RTX 4090 Mobile scores 27,048 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Enthusiast tier as a Recent generation graphics card. It is built on the Ada Lovelace (2022−2024) architecture (codename: AD103), manufactured on a 4 nm process— smaller process nodes improve power efficiency and transistor density. It packs 9728 shader units (the primary compute units for rendering pixels), 304 TMUs (texture mapping units), and 112 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 32.98 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1695 MHz from a base of 1335 MHz.
