Graphics Performance
The Radeon HD 6990 scores 3,014 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 3 (2010−2013) architecture (codename: Antilles), manufactured on a 40 nm process— smaller process nodes improve power efficiency and transistor density. It packs 1536 ×2 shader units (the primary compute units for rendering pixels), 96 ×2 TMUs (texture mapping units), and 32 ×2 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 2.55 TFLOPS ×2 — this measures the theoretical peak floating-point performance.
