HP Z4 G4 Workstation Xeon W-2235 3.8GHz 16GB DDR4 1TB NVMe RTX 4000 8GB Windows 11 Pro

Professional single-processor workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor running at 3.8GHz with a 4.6GHz turbo frequency. It ships with 16GB of DDR4 2933 ECC registered memory, a 1TB PCIe NVMe solid-state drive and an Nvidia Quadro RTX 4000 graphics card with 8GB GDDR6 memory. Windows 11 Pro 64-bit is pre-installed and digitally activated for immediate deployment.

Upgrades from earlier Xeon or Core X systems

This configuration replaces single-processor towers limited to lower core counts or slower memory speeds, delivering six cores and support for up to 512GB DDR42933 ECC RAM. The jump is worth it when your workflows demand ISV-certified stability for 3D CAD, rendering or GPU-accelerated compute and you need the 256-bit memory interface of the RTX 4000 for large models. Buyers who need dual-processor scaling or more than 512GB memory capacity should look elsewhere.

Verify your peripheral and power needs

The workstation includes a 1000W 80 Plus Gold power supply rated at 90% efficiency and provides three DisplayPort 1.4 outputs plus one USB-C video connector on the graphics card. Confirm your monitors match these display interfaces and that your rack or desk space accommodates a mid-tower chassis. Integrated Gigabit Ethernet and high-definition audio are onboard; no wireless networking hardware is included.
