Graphics Performance

The RadeonT Vega 8 scores 1,894 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Entry Level tier as a Aging generation graphics card. It is built on the GCN 5.1 (2018−2022) architecture (codename: Cezanne), manufactured on a 7 nm process— smaller process nodes improve power efficiency and transistor density. It packs 448 shader units (the primary compute units for rendering pixels), 28 TMUs (texture mapping units), and 8 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 1.702 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1900 MHz from a base of 300 MHz.
