Graphics Performance
The Tesla K40c scores 4,495 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: GK180), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 2880 shader units (the primary compute units for rendering pixels), 240 TMUs (texture mapping units), and 48 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 5.046 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 876 MHz from a base of 745 MHz.
