Quadro K4000 3GB workstation GPU

The IBM Nvidia Quadro K4000 is a full-height workstation graphics card built on the NVIDIA Quadro K4000 GPU with 768 CUDA cores. It connects via PCI Express 2.0 x16 and ships in new condition. This card targets professionals who need certified driver stability for CAD, DCC and visualisation workloads on a single-slot form factor. It is not suited for buyers who require more than 3GB of frame buffer for large assemblies or high-resolution textures.

3GB GDDR5 192-bit memory and bandwidth

The card provides 3GB of GDDR5 memory across a 192-bit interface delivering 134 GBps of bandwidth. This capacity handles moderate 3D models, 1080p viewport work and multi-monitor setups using the two DisplayPort and one DVI outputs. It runs out of headroom when scenes exceed the 3GB frame buffer or when compute tasks demand more than 768 CUDA cores for parallel processing.

Thermals noise and power in normal use

As a PCIe 2.0 x16 add-in card, the Quadro K4000 draws power from the slot and a supplemental connector, operating within typical workstation thermal envelopes. The reference cooler maintains acceptable temperatures during sustained viewport and render sessions without excessive fan noise. Power draw remains consistent with the Kepler architecture profile for this class of professional GPU.

Questions about this item

Will the PCIe 2.0 x16 interface of the Quadro K4000 limit performance if I keep my older PCIe 1.0 motherboard?

The card runs at PCIe 2.0 x16 speeds and is backward compatible with PCIe 1.0 slots, though bandwidth will be halved compared to a native 2.0 connection.

How can I verify the 768 CUDA cores and 3GB GDDR5 memory are active after installing the K4000?

Open the NVIDIA Control Panel or run a tool like GPU-Z; both will report 768 CUDA cores and 3 GB of GDDR5 on a 192-bit bus.

Does the 03T8312 include the full-height bracket and both DisplayPort cables, or must I buy them separately?

The card ships with the full-height bracket already attached; DisplayPort and DVI cables are not included and must be purchased separately.
