Built for compute-heavy workloads

This HP Z4 G4 workstation pairs a 6-core Intel Xeon W-2235 running at 3.8 GHz with a 4.6 GHz turbo boost with 256 GB of DDR4 2933 ECC registered memory. The 500 GB PCIe NVMe SSD and NVIDIA Quadro RTX 5000 16 GB GDDR6 graphics card support 3D CAD, rendering and GPU-accelerated tasks. Windows 11 Pro is pre-installed for immediate deployment.

1000 W 80 Plus Gold supply handles peak loads

The integrated 1000 W power supply operates at 90 % efficiency, delivering stable power to the CPU and GPU under sustained professional workloads. Tool-less internal access simplifies maintenance while the mid-tower chassis manages airflow for the Xeon processor and Quadro graphics during extended compute sessions.

Quad DisplayPort 1.4 plus VirtualLink for VR

Four DisplayPort 1.4 outputs and a VirtualLink connector drive multiple high-resolution displays or VR headsets directly from the Quadro RTX 5000. ISV certification with leading professional applications ensures reliability for critical projects, while the 512 GB maximum memory ceiling allows future expansion beyond the factory 256 GB configuration.

Questions about this item

How is the Quadro RTX 5000 installed in the mid-tower chassis, and which power connection is often missed?

The GPU seats in a full-length PCIe x16 slot and draws power from the 1000 W 80 Plus Gold supply via an 8-pin connector that must be fully latched or the card will not initialise.

What maintenance will the 256 GB DDR4 2933 ECC memory require over its service life?

The registered ECC DIMMs have no moving parts; only occasional slot reseating is needed if the workstation is moved, otherwise they run for the system lifetime without replacement.

Which limit appears first when the Xeon W-2235 sustains 4.6 GHz turbo across all six cores?

The 1000 W 80 Plus Gold power supply and chassis thermal design cap sustained all-core turbo; the CPU will throttle to its 3.8 GHz base once the package power budget is reached.
