The PNY NVIDIA RTX PRO 4000 SFF is a professional workstation graphics card built on NVIDIA's Blackwell architecture, fitted with 24GB of GDDR7 memory with ECC (error-correcting code) protection on a 192-bit bus, and a PCIe 5.0 x16 interface. The "SFF" (small form factor) dual-slot, 70W-OEM design is built specifically to fit into compact workstation chassis and low-power server/workstation builds where a full-size, high-wattage GPU wouldn't fit or wouldn't be supported by the power supply -- a common requirement for OEM system integrators. Output is via four Mini DisplayPort 2.1b connectors, supporting multiple high-resolution displays simultaneously. Aimed at CAD, 3D rendering, AI/ML and other GPU-accelerated professional workloads rather than gaming, where NVIDIA's consumer GeForce line is the norm instead.
