Graphics Performance
The Radeon RX 6900 XT scores 26,729 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Enthusiast tier as a Aging generation graphics card. It is built on the RDNA 2.0 (2020−2025) architecture (codename: Navi 21), manufactured on a 7 nm process— smaller process nodes improve power efficiency and transistor density. It packs 5120 shader units (the primary compute units for rendering pixels), 320 TMUs (texture mapping units), and 128 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 23.04 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 2250 MHz from a base of 1825 MHz.
