Graphics Performance

The RTX A4000 Mobile scores 14,782 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Mid-Range tier as a Aging generation graphics card. It is built on the Ampere architecture (codename: GA104), manufactured on a 8 nm process— smaller process nodes improve power efficiency and transistor density. It packs 5120 shader units (the primary compute units for rendering pixels), 160 TMUs (texture mapping units), and 80 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 17.2 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1680 MHz from a base of 1140 MHz.
