HP Z4 G4 Mid-Tower Workstation Xeon W-2235 3.8GHz 64GB DDR4 1TB NVMe Quadro P5000 16GB Windows 11 Pro

Professional Workstation Core

The HP Z4 G4 mid-tower workstation delivers professional single-processor performance for demanding workflows. It is built around an Intel Xeon W-2235 3.8GHz six-core processor reaching 4.6GHz turbo with 64GB DDR4 2933 ECC registered memory. This configuration targets engineers and creators running compute-intensive applications. Buyers needing dual-processor scaling or higher core counts should evaluate larger platforms.

Certified Graphics And Power

The bundled Nvidia Quadro P5000 16GB GDDR5X 256-bit card provides four DisplayPort 1.4 outputs and one DVI-D dual-link connector for multi-display professional visualisation. ISV certification ensures tested compatibility with leading CAD, rendering and simulation software. The integrated 1000W 80 Plus Gold 90% efficient power supply supports the graphics card and future internal upgrades without requiring a separate PSU purchase. Systems needing more than four display outputs require additional graphics hardware.

Memory And Storage Ceiling

The platform supports a maximum of 512GB DDR4-2933 ECC SDRAM across its memory slots, defining the upper limit for large dataset and complex simulation workloads. The installed 1TB M.2 NVMe solid-state drive handles the operating system and active projects with fast PCIe responsiveness. Additional internal bays and M.2 slots accept SATA and further PCIe NVMe drives for capacity expansion. Buyers whose workloads exceed 512GB memory capacity must consider alternative workstation architectures.
