NVIDIA Quadro K4000 3GB GDDR5 workstation graphics card

Professional workstation GPU for legacy pipelines

The Quadro K4000 delivers 3 GB of GDDR5 memory on a 256-bit bus through a PCI Express 2.0 x16 slot. It targets engineers and designers maintaining certified applications that rely on DirectX 11.2 and OpenGL 4.5 compatibility. The single-slot, full-height design fits standard workstation chassis while drawing 80 W TGP via a 6-pin auxiliary connector.

PCIe 2.0 bandwidth caps modern workload throughput

The PCI Express 2.0 x16 interface limits host-to-device transfer rates compared with newer generations, which can throttle compute-heavy tasks or high-resolution texture streaming. Display outputs max out at 4096 x 2160 digital and 2048 x 1536 at 85 Hz analogue across two DisplayPort 1.2 and one DVI port. Only three displays may be active simultaneously, restricting multi-monitor configurations beyond that count.

Upgrades Fermi or entry-level Kepler cards

Moving from earlier Quadro models or consumer GeForce boards gains ISV-certified drivers, 3 GB frame buffer and 256-bit memory width for larger assemblies and viewports. The jump is worthwhile when legacy software mandates Kepler architecture or DirectX 11.2 feature level. Buyers needing more than three concurrent displays, higher API versions or greater memory capacity should consider newer workstation platforms.
