Graphics Performance
The Radeon HD 7420G scores 316 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: Malta), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 2048 ×2 shader units (the primary compute units for rendering pixels), 128 ×2 TMUs (texture mapping units), and 32 ×2 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 4.096 TFLOPS ×2 — this measures the theoretical peak floating-point performance. Boost clock reaches 1000 MHz from a base of 950 MHz.
