HP Z4 G4 Business Desktop Xeon W-2235 32GB 4TB NVMe Quadro P4000 Windows 11 Pro

Mid-tower workstation for professional workloads

The HP Z4 G4 is a business desktop built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory and a 4 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8 GB GDDR5 memory provides four DisplayPort 1.4 outputs for multi-display setups.

Suited for certified applications and large datasets

This configuration targets engineers, designers and analysts who rely on ISV-certified stability for 3D CAD, rendering and simulation workloads. The 512 GB maximum memory ceiling supports very large datasets, while the Quadro driver stack is validated for professional software. Buyers who need more than a single processor socket or who require consumer-grade gaming features should consider other platforms.

Sustained performance with a 1000 W 80

A 1000 W power supply rated at 90 percent efficiency delivers stable power during extended compute or render jobs. The mid-tower chassis offers tool-less access and multiple PCIe slots for adding storage or expansion cards without downtime. Integrated Gigabit Ethernet and high-definition audio handle baseline connectivity while the workstation maintains thermal headroom under continuous load.
