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.

Questions about this item

Is the 3 GB GDDR5 memory enough for my CAD and rendering workloads?

The card provides 3 GB of GDDR5 memory on a 256-bit bus, which handles medium-sized models and textures in professional OpenGL 4.5 and DirectX 11.2 applications.

What real-world performance does the Kepler GPU deliver in professional apps?

The Kepler-based Quadro K4000 runs certified drivers for CAD, DCC and visualization software, driving up to three displays at 4096 x 2160 digital or 2048 x 1536 analog resolution.

Will the PCI Express 2.0 x16 interface limit throughput on a modern motherboard?

The board uses a PCI Express 2.0 x16 slot; on newer platforms it operates at 2.0 speeds, which still supplies ample bandwidth for the 80 W TGP GPU and 256-bit memory subsystem.
