HP Z4 G4 Business Desktop Xeon W-2235 3.8GHz 16GB DDR4 2TB NVMe RTX 4000 8GB Windows 11 Pro

Professional Workstation Performance

The HP Z4 G4 is a mid-tower business desktop built for compute-intensive workflows. It ships with an Intel Xeon W-2235 processor running at 3.8GHz with a 4.6GHz turbo frequency across six cores. The system includes 16GB of DDR4 2933 ECC registered memory in a dual-channel configuration. Windows 11 Pro is pre-installed and digitally activated for immediate deployment.

Upgrading From Entry Systems

This configuration replaces older workstations limited to four cores, non-ECC memory or SATA-only storage. The jump is worth it when your applications demand certified GPU acceleration, error-correcting memory for data integrity or PCIe NVMe speeds for large project files. The LGA 2066 platform supports up to 512GB of DDR42933 ECC SDRAM for future expansion. Buyers who need only basic office productivity or single-monitor setups will not utilise the certified graphics and expandability this platform provides.

Build Integration Requirements

The Nvidia Quadro RTX 4000 adds 8GB of GDDR6 memory on a 256-bit bus with three DisplayPort 1.4 outputs and one USB-C connector for professional displays. A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power for the GPU and additional PCIe cards. The 2TB NVMe SSD occupies one M.2 slot, leaving internal bays and further M.2 positions open for SATA or PCIe storage arrays. Tool-less chassis access simplifies the installation of extra memory, storage or add-in cards without proprietary tools.
