Graphics Performance
The Quadro K420 scores 726 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 Kepler (2012−2018) architecture (codename: GK104), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 1344 shader units (the primary compute units for rendering pixels), 112 TMUs (texture mapping units), and 32 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 2.107 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 784 MHz from a base of 771 MHz.
