HP Z4 G4 Workstation Xeon W-2225 16GB DDR4 1TB NVMe RTX 5000 16GB

HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 four-core processor running at 4.1 GHz with 4.6 GHz turbo. It ships with 16 GB of DDR4 2933 ECC registered memory, a 1 TB PCIe NVMe SSD and an NVIDIA Quadro RTX 5000 graphics card with 16 GB GDDR6. Windows 11 Pro is pre-installed.

Who this suits and who should look elsewhere

This workstation fits engineers, designers and analysts who need ISV-certified stability for 3D CAD, rendering or GPU-accelerated simulation workloads. The four PCIe slots and toolless chassis simplify future upgrades. Buyers who want more storage bays than the M.2 and internal bays provide, or who need dual-processor throughput for large-scale compute clusters, should consider other platforms.

Deciding specification: Xeon W-2225 four-core CPU

The Intel Xeon W-2225 delivers 4.1 GHz base and 4.6 GHz turbo frequencies on four cores with ECC memory support. That clock-speed-to-core balance determines whether single-threaded CAD tasks or lightly threaded simulation jobs finish quickly enough. If your workflow scales across many more threads, a higher-core-count Xeon W or a dual-socket system would be required.
