Professional Workstation for Demanding Workflows

The HP Z4 G4 is a new mid-tower business desktop built around a 6-core Intel Xeon W-2235 processor running at 3.8GHz with 4.6GHz turbo. It ships with 32GB of DDR4 2933 ECC registered memory in a 4x8GB configuration and a 500GB M.2 NVMe solid-state drive. Graphics are handled by an Nvidia Quadro RTX 5000 with 16GB GDDR6 memory on a 256-bit bus, offering four DisplayPort 1.4 outputs and VirtualLink. A 1000W 80 Plus Gold power supply and Windows 11 Pro complete the package.

Suited for Certified Professional Applications

This system targets users who need ISV-certified stability for 3D CAD, rendering, visualization and GPU-accelerated workloads. The Xeon platform supports up to 512GB of DDR4 ECC memory for large datasets and complex simulations. Buyers who require dual-processor scaling or consumer-focused gaming features should evaluate alternative platforms.

Verify Expansion and Power Requirements

Confirm that your workspace accommodates a mid-tower chassis and that your display inputs match the available DisplayPort 1.4 and VirtualLink connectors. The integrated Gigabit Ethernet and high-definition audio handle standard connectivity. Check that your regional mains supply is compatible with the 1000W 80 Plus Gold unit before ordering.
