HP Z4 G4 Business Desktop Xeon W-2235 32GB 500GB NVMe Quadro P2000 5GB Windows 11 Pro

Mid-tower workstation for professional workflows

The HP Z4 G4 is a new mid-tower business desktop built around an Intel Xeon W-2235 processor with 6 cores running at 3.8 GHz and a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory in a 4×8 GB configuration and a 500 GB PCIe NVMe solid-state drive. The system includes an NVIDIA Quadro P2000 graphics card with 5 GB GDDR5 memory and a 160-bit interface, and it runs Windows 11 Pro 64-bit.

Expandable chassis with high-efficiency power

The mid-tower form factor provides multiple internal storage bays and M.2 slots for combinations of SATA and PCIe NVMe drives, alongside several PCIe slots for add-in cards. Tool-less access simplifies upgrades and maintenance of memory, storage and expansion cards. A 1000 W 80 Plus Gold power supply rated at 90 % efficiency delivers stable power for the Xeon processor, professional graphics and additional components without requiring an external power brick.

Sustained performance under certified workloads

The Xeon W-2235 maintains high clock frequencies across all 6 cores during extended compute-intensive tasks such as 3D CAD, rendering and simulation. ECC memory protects data integrity for large datasets over long runs, while the Quadro P2000 drives up to four DisplayPort 1.4 displays for continuous visualisation work. ISV certification with leading professional applications ensures reliable operation for critical projects rather than short benchmark bursts.
