HP Quadro K4000M mobile workstation GPU

The HP Quadro K4000M is a mobile workstation graphics card built for the EliteBook 8770w platform. It connects through an MXM 3.0 slot and uses the NVIDIA Kepler architecture. Professional users in CAD, DCC and scientific visualisation can deploy it as a direct replacement or upgrade for compatible HP laptops.

4GB GDDR5 frame buffer with CUDA acceleration

The card provides 4GB of GDDR5 memory across a 256-bit interface running at 2800 MHz. This bandwidth supports large assemblies, high-resolution textures and GPU-accelerated compute through 960 CUDA cores at 600 MHz core clock. DirectX 11.1 compatibility ensures broad ISV application support without additional driver configuration.

Kepler architecture limits for modern workloads

The 4GB memory capacity handles moderate datasets and multi-monitor setups comfortably within the 256-bit bus width. Complex scenes exceeding the frame buffer will page to system memory, reducing throughput. The Kepler architecture and DirectX 11.1 feature set restrict use with newer APIs and modern rendering pipelines that require Shader Model 6.x or Vulkan 1.2 features.

Questions about this item

Will the MXM 3.0 slot need to be re-pasted or the thermal pads replaced after extended use?

The MXM 3.0 module uses a heatsink contact surface that typically requires fresh thermal compound and new pads when the card is removed or after several years of high-load operation.

Does the 256-bit memory bus or the 960 CUDA cores reach their limit first during sustained rendering?

The 256-bit GDDR5 interface at 2800 MHz often saturates before the 960 CUDA cores at 600 MHz in memory-heavy workloads.

How much heat and fan noise should I expect from the Quadro K4000M running all day in an EliteBook 8770w?

The Kepler GPU draws enough power under continuous load to spin the workstation fans at audible speeds, producing noticeable warmth near the exhaust vents.
