Graphics Performance
The Tesla K20c scores 4,432 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: GK110), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 2496 shader units (the primary compute units for rendering pixels), 208 TMUs (texture mapping units), and 40 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 3.524 TFLOPS — this measures the theoretical peak floating-point performance.
