HP Z4 G4 Mid-Tower Workstation Xeon W-2225 4.1GHz 128GB DDR4 2TB NVMe Quadro P5000 16GB Windows 11 Pro

Z4 G4 Xeon W-2225 Workstation

The HP Z4 G4 is a mid-tower workstation 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 128 GB of DDR4 2933 ECC registered memory in a 4 x 32 GB configuration and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory provides four DisplayPort 1.4 outputs and a dual-link DVI-D connector. Windows 11 Pro is pre-installed for professional environments.

Sustained compute and memory throughput

The Xeon W-2225 maintains its turbo frequency across all four cores during prolonged workloads, supported by the 1000 W 80 Plus Gold power supply rated at 90 percent efficiency. The 512 GB maximum memory capacity allows future expansion for larger datasets, while the DDR4 2933 ECC modules deliver error correction for data integrity during extended simulations. The Quadro P5000 256-bit memory interface sustains bandwidth for GPU-accelerated rendering and visualization tasks without throttling under continuous load.

Thermal management and acoustics

The mid-tower chassis uses directed airflow paths to cool the processor, memory and graphics card under typical professional workloads. The 1000 W Gold-rated supply operates efficiently, reducing waste heat and acoustic output compared to lower-efficiency units. Tool-less access simplifies cleaning of internal components to maintain thermal performance over time. Integrated gigabit Ethernet and high-definition audio add minimal thermal load to the system.
