Technical Analysis
Detailed breakdown of Radeon HD 6450 specifications and capabilities.
Graphics Performance
The Radeon HD 6450 scores 198 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 3 (2010−2013) architecture (codename: Cayman), manufactured on a 40 nm process— smaller process nodes improve power efficiency and transistor density. It packs 1408 shader units (the primary compute units for rendering pixels), 88 TMUs (texture mapping units), and 32 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 2.253 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 800 MHz.
