Graphics Performance
The RadeonT 660M scores 2,221 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Entry Level tier as a Recent generation graphics card. It is built on the RDNA 2.0 (2020−2025) architecture (codename: Rembrandt+), manufactured on a 6 nm process— smaller process nodes improve power efficiency and transistor density. It packs 384 shader units (the primary compute units for rendering pixels), 24 TMUs (texture mapping units), and 16 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 1.459 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1900 MHz from a base of 1500 MHz.
