Graphics Performance

The GeForce FX 5900ZT scores 33 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 Fermi 2.0 (2010−2014) architecture (codename: GF110), manufactured on a 40 nm process— smaller process nodes improve power efficiency and transistor density. It packs 1024 ×2 shader units (the primary compute units for rendering pixels), 64 ×2 TMUs (texture mapping units), and 48 ×2 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 1.244 TFLOPS ×2 — this measures the theoretical peak floating-point performance.
