Graphics Performance
The Radeon HD 8790M scores 1,306 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 GCN 1.0 (2012−2020) architecture (codename: Mars), manufactured on a 28 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 8 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 0.6912 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 900 MHz from a base of 850 MHz.
