Technical Analysis

Detailed breakdown of Radeon HD 7640G specifications and capabilities.

Graphics Performance

The Radeon HD 7640G scores 454 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 TeraScale 2 (2009−2015) architecture (codename: Turks), manufactured on a 40 nm process— smaller process nodes improve power efficiency and transistor density. It packs 480 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: 0.576 TFLOPS — this measures the theoretical peak floating-point performance.
