HP Z4 G4 Business Desktop Xeon W-2235 256GB DDR4 4TB NVMe Quadro P4000 8GB Windows 11 Pro

Workstation for compute-intensive workloads

This HP Z4 G4 mid-tower workstation is built for professionals who run compute-intensive applications such as 3D CAD, rendering, visualization and GPU-accelerated workloads. It ships with Windows 11 Pro and carries ISV certification for leading professional software. Buyers who need a compact small-form-factor chassis or an integrated display should look elsewhere.

256GB DDR4 2933 ECC memory capacity
