HP Z4 G4 Workstation Xeon W-2235 64GB DDR4 1TB NVMe Quadro RTX 5000 16GB Windows 11 Pro

Professional Workstation Build

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency across six cores. It ships with 64 GB of DDR4 2933 ECC registered memory in a four-module configuration and a 1 TB PCIe NVMe solid-state drive. Graphics are handled by an Nvidia Quadro RTX 5000 with 16 GB of GDDR6 memory on a 256-bit bus, driving four DisplayPort 1.4 outputs and a VirtualLink connector. The system includes a 1000 W 80 Plus Gold power supply and Windows 11 Pro.

Suited for ECC Memory Workloads

This configuration targets professionals who need error-correcting memory and ISV-certified stability for 3D CAD, rendering, visualization or GPU-accelerated compute. The single-socket Xeon platform and Quadro RTX 5000 combination is chosen for certified driver support in those applications. Buyers who want more storage bays or multiple graphics cards should look at larger chassis platforms. Users without ECC requirements or certified-application needs may find equivalent throughput on consumer-grade hardware.

Mid-Tower Expansion Ready

The mid-tower form factor provides multiple internal drive bays and M.2 slots for mixing SATA and PCIe NVMe devices alongside the factory 1 TB boot drive. Four PCIe slots allow additional capture, networking or compute cards without removing the Quadro RTX 5000. Toolless access simplifies memory upgrades up to the 512 GB platform maximum or storage reconfiguration. The 1000 W Gold-rated supply delivers headroom for high-wattage add-in cards while the integrated Gigabit Ethernet and high-definition audio handle baseline connectivity.
