HP Z4 G4 Business Desktop Xeon W-2225 4.1GHz 32GB DDR4 1TB NVMe Quadro P4000 8GB Windows 11 Pro

HP Z4 G4 Workstation for Professional Compute

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo frequency across four cores. It ships with 32 GB of DDR4 2933 ECC registered memory in a four-module configuration and a 1 TB PCIe NVMe solid-state drive. The Nvidia Quadro P4000 provides 8 GB of GDDR5 memory on a 256-bit bus with four DisplayPort 1.4 outputs. Windows 11 Pro is pre-installed and digitally activated.

Sustained Load Behaviour with 1000 W Gold Supply

A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency delivers stable power for extended rendering or simulation sessions. The Xeon W-2225 maintains its turbo frequency under multi-core workloads supported by the workstation thermal design. ECC memory corrects single-bit errors in real time, preserving data integrity during long compute runs. The Quadro P4000 drivers are ISV-certified for consistent performance in professional 3D CAD and visualization applications.

Upgrade Path from Earlier Workstations

This system replaces older single-processor towers that max out at lower memory capacities or lack NVMe boot drives. The 512 GB maximum memory ceiling and multiple M.2 slots allow future expansion for larger datasets. Four PCIe slots and toolless chassis access simplify adding storage controllers or a second GPU when workloads grow. Buyers who need dual-socket scaling or more than four CPU cores should evaluate higher-tier platforms.
