Graphics Performance

The Radeon HD 6850 X2 scores 2,534 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 TeraScale 2 (2009−2015) architecture (codename: Barts), manufactured on a 40 nm process— smaller process nodes improve power efficiency and transistor density. It packs 960 ×2 shader units (the primary compute units for rendering pixels), 48 ×2 TMUs (texture mapping units), and 32 ×2 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 1.536 TFLOPS ×2 — this measures the theoretical peak floating-point performance.
