HP Z4 G4 Business Desktop Xeon W-2225 4.1GHz 256GB DDR4 4TB NVMe RTX 4000 8GB Windows 11 Pro

HP Z4 G4 Mid-Tower Workstation

This HP Z4 G4 mid-tower workstation is built for professionals who need reliable single-processor performance in a compact chassis. It ships new with Windows 11 Pro and targets engineers, designers and data scientists running certified ISV applications. The system combines an Intel Xeon W-2225 processor with professional NVIDIA graphics for compute-intensive workflows.

Tool-free access simplifies upgrades and maintenance

The chassis features tool-less entry to internal components, making memory, storage and PCIe card changes straightforward. Eight populated DDR4 slots mean adding more RAM requires removing existing 32GB modules first. The 1000W 80 Plus Gold power supply delivers 90% efficiency but uses proprietary cabling that limits aftermarket GPU swaps without adapter kits.

256GB DDR4 ECC and 4TB NVMe handle large datasets

With 256GB of DDR4 2933 ECC registered memory across eight slots, the system supports up to 512GB total for complex simulations and multi-tasking. The 4TB PCIe NVMe drive provides fast project storage and boot responsiveness. The Quadro RTX 4000 8GB GDDR6 card drives up to four displays via three DisplayPort 1.4 outputs and one USB-C connector for professional visualisation.
