Graphics Performance

The Radeon Pro V620 MxGPU scores 15,633 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the High-End tier as a Legacy generation graphics card. It is built on the RDNA 2.0 architecture (codename: Vega 10), manufactured on a 14 nm process— smaller process nodes improve power efficiency and transistor density. It packs 3584 ×2 shader units (the primary compute units for rendering pixels), 224 ×2 TMUs (texture mapping units), and 64 ×2 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 10.75 TFLOPS ×2 — this measures the theoretical peak floating-point performance. Boost clock reaches 1500 MHz from a base of 1000 MHz.
