HP Z4 G4 Business Desktop Xeon W-2225 4.1GHz 64GB DDR4 2TB NVMe RTX 4000 8GB

HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 processor with four cores running at 4.1 GHz and a 4.6 GHz turbo frequency. It ships with 64 GB of DDR4 2933 ECC registered memory across four 16 GB modules and a 2 TB PCIe NVMe solid-state drive. Professional graphics are provided by an Nvidia Quadro RTX 4000 card with 8 GB of GDDR6 memory on a 256-bit bus, driving three DisplayPort 1.4 outputs and one USB-C connector. A 1000 W 80 Plus Gold power supply and Windows 11 Pro complete the package.

Suited for ISV-certified CAD and simulation

This workstation targets engineers, designers and analysts who rely on certified drivers for 3D CAD, rendering, visualisation and GPU-accelerated compute workflows. The Xeon platform delivers ECC memory integrity and up to 512 GB total capacity for large datasets and complex simulations. Buyers who need higher core counts for heavy multi-threaded rendering or who require multiple high-end graphics cards should look at dual-socket or larger-chassis alternatives.

2 TB NVMe boot drive and 64 GB ECC RAM

The 2 TB NVMe SSD provides fast system responsiveness and ample space for active project files, while the 64 GB DDR4 2933 ECC configuration handles substantial assemblies and datasets without paging. Memory headroom extends to 512 GB across the platform’s slots, so future expansion is straightforward. The single RTX 4000 8 GB frame buffer limits extremely large scene rendering or multi-GPU compute scaling, which would demand additional graphics memory or a second card.
