Graphics Performance
The Iris Plus Graphics 640 scores 1,353 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 Generation 9.5 (2016−2020) architecture (codename: Kaby Lake GT3e), manufactured on a 14 nm++ process— smaller process nodes improve power efficiency and transistor density. It packs 384 shader units (the primary compute units for rendering pixels), 48 TMUs (texture mapping units), and 6 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 0.8448 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1100 MHz from a base of 300 MHz.
