Single-processor workstation

The HP Z4 G4 is a mid-tower workstation built around a single Intel Xeon W-2235 processor for professional compute workloads. It targets engineers and designers who need certified application stability and expandable memory in a serviceable chassis.

256GB DDR4 with ECC headroom

Eight 32GB DDR4 2933 ECC registered modules deliver 256GB of error-correcting memory today, with the platform supporting up to 512GB for larger datasets. The 2TB PCIe NVMe SSD provides fast primary storage, while additional internal bays and M.2 slots remain available for SATA or further NVMe expansion.

1000W Gold supply and Quadro RTX 4000

A 1000W 80 Plus Gold power supply feeds the Nvidia Quadro RTX 4000 8GB GDDR6 card, which outputs through three DisplayPort 1.4 connectors and one USB-C. Tool-less access and multiple PCIe slots simplify future GPU or add-in card upgrades, and integrated Gigabit Ethernet handles wired connectivity.
