HP Z4 G4 Business Desktop Xeon W-2235 3.8GHz 32GB DDR4 1TB NVMe Quadro P4000 8GB Windows 11 Pro

Mid-tower Xeon workstation for professional

The HP Z4 G4 is a new business desktop built around an Intel Xeon W-2235 processor running at 3.8GHz with a 4.6GHz turbo across six cores. It ships with 32GB of DDR4 2933 ECC registered memory in a four-module configuration and a 1TB PCIe NVMe solid-state drive. An NVIDIA Quadro P4000 graphics card provides 8GB of GDDR5 memory on a 256-bit bus with four DisplayPort 1.4 outputs for multi-monitor setups. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Tool-less chassis simplifies upgrades

The mid-tower design offers toolless access to internal components, multiple PCIe slots, and additional M.2 and SATA bays for storage expansion. The LGA 2066 socket supports the installed Xeon W-2235, while the motherboard accepts up to 512GB of DDR4 ECC memory across its slots. A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers ample headroom for the Quadro P4000 and future add-in cards. Integrated gigabit ethernet and high-definition audio handle networking and sound without extra cards.

Sustained performance backed by ISV certification

The workstation is engineered and tested to meet industry standards with certification across leading professional applications for 3D CAD, rendering, visualization, and GPU-accelerated workloads. The Quadro P4000 maintains stable output under continuous compute loads, supported by the Gold-rated power supply and the chassis airflow design. ECC memory protects data integrity during long simulations or large dataset processing. The platform targets users who need certified reliability rather than consumer-grade components.
