Graphics Performance

The Radeon RX Vega 8 scores 1,540 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 GCN 5.0 (2017−2020) architecture (codename: Vega), manufactured on a 14 nm process— smaller process nodes improve power efficiency and transistor density. It packs 512 shader units (the primary compute units for rendering pixels), 32 TMUs (texture mapping units), and 8 ROPs (render output units that handle final pixel output). Boost clock reaches 1190 MHz from a base of 720 MHz.
