Graphics Performance
The GeForce GTX 660 scores 4,040 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Budget tier as a Legacy generation graphics card. It is built on the Kepler (2012−2018) architecture (codename: GK106), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 960 shader units (the primary compute units for rendering pixels), 80 TMUs (texture mapping units), and 24 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 1.981 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1033 MHz from a base of 980 MHz.
