The Nvidia RTX PRO 4000 SFF is a professional workstation graphics card from Nvidia's Blackwell generation, built in a small-form-factor (SFF) design so it fits compact/slimline workstation towers rather than only full-size desktops. This PNY-manufactured card carries 24GB of GDDR7 memory with ECC (error-correcting code) support — a feature aimed at professional/scientific workloads where memory error detection matters, unlike consumer GeForce cards. It connects over PCIe 5.0 x16, outputs via four Mini DisplayPort 2.1b connections, and draws just 70W, low enough to run without extra PCIe power connectors in many systems. It's aimed at CAD, 3D design, and professional visualisation users needing certified workstation drivers in a smaller physical footprint than a full-height professional GPU.
