Graphics Performance

The Radeon Pro Vega 20 scores 5,169 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Budget tier as a Legacy generation graphics card. It is built on the GCN 5.0 (2017−2020) architecture (codename: Vega 12), manufactured on a 14 nm process— smaller process nodes improve power efficiency and transistor density. It packs 1280 shader units (the primary compute units for rendering pixels), 80 TMUs (texture mapping units), and 32 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 3.284 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1283 MHz from a base of 815 MHz.
