Workstation Kepler GPU with 3 GB GDDR5

The NVIDIA Quadro K4000 is a Kepler-generation workstation graphics card built for professional 3D and compute workflows. It connects through a PCI Express 2.0 x16 slot and occupies a single full-height bracket space. The board carries 3 GB of GDDR5 memory across a 256-bit bus and draws up to 80 W TGP from a single 6-pin auxiliary power connector. Drivers support DirectX 11.2 and OpenGL 4.5 for certified application stability.

Two DisplayPort 1.2 and one DVI for three displays

This card suits users who need up to three simultaneous monitors at digital resolutions up to 4096 x 2160 or analog up to 2048 x 1536 at 85 Hz via two DisplayPort 1.2 outputs and one DVI port. It is not for buyers who require four or more active displays, modern API features such as DirectX 12 or Vulkan, or a rear mounting bracket included in the box.

256-bit memory interface width

The 256-bit memory interface width is the specification that determines whether bandwidth matches the dataset size in typical CAD, DCC or GPU-compute tasks. A narrower bus would limit throughput for large models, while a wider bus would indicate a higher-tier part not represented by this SKU.

Questions about this item

How much heat does the 80W TGP generate when the card runs all day?

The 80W TGP means the card draws up to 80 watts under load, so expect a corresponding amount of heat that a normal workstation case fan can handle.

My power supply only has 6-pin connectors; will the 6-pin auxiliary power connector on this card work?

Yes, the card uses a single 6-pin auxiliary power connector, so a PSU with one 6-pin lead is sufficient.

Can I drive my older 2048 x 1536 analog monitor from the DVI port while using two DisplayPort 1.2 screens?

Yes, the DVI port supports 2048 x 1536 at 85 Hz analog, and the two DisplayPort 1.2 outputs can each drive 4096 x 2160 digital displays simultaneously.
