Technical Analysis
Detailed breakdown of Radeon R9 290X / 390X specifications and capabilities.
Graphics Performance
The Radeon R9 290X / 390X scores 8,380 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Mid-Range tier as a Legacy generation graphics card. It is built on the GCN 2.0 (2013−2017) architecture (codename: Grenada), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 2816 shader units (the primary compute units for rendering pixels), 176 TMUs (texture mapping units), and 64 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 5.914 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1050 MHz.
