HP Z4 G4 Business Desktop Xeon W-2235 256GB DDR4 500GB NVMe Quadro RTX 4000 8GB Windows 11 Pro

Intel Xeon W-2235 workstation for professional

This HP Z4 G4 mid-tower workstation is built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 256 GB of DDR4 2933 ECC registered memory and a 500 GB NVMe solid-state drive. An Nvidia Quadro RTX 4000 graphics card with 8 GB GDDR6 provides certified performance for 3D CAD, rendering and visualisation tasks. Windows 11 Pro is pre-installed and digitally activated.

Verify power, display outputs

The unit includes a 1000 W 80 Plus Gold power supply rated at 90 % efficiency, so confirm your mains circuit can support this draw. The Quadro RTX 4000 offers three DisplayPort 1.4 connectors and one USB-C graphics port; ensure your monitors match these inputs or have suitable adapters. Memory is populated as eight 32 GB modules filling all slots, so any future expansion up to the 512 GB maximum will require replacing existing DIMMs. No display is included in the package.

Single-processor platform

The LGA 2066 single-socket design targets workloads that benefit from high per-core frequency rather than dual-processor scaling. Multiple PCIe slots and tool-less chassis access allow straightforward addition of storage drives or specialised add-in cards. Integrated Gigabit Ethernet and high-definition audio handle baseline connectivity without consuming expansion slots. The mid-tower form factor fits standard rack or desk deployments while leaving room for the certified professional graphics card.
