HP Z4 G4 Workstation Xeon W-2225 4.1GHz 128GB DDR4 4TB NVMe RTX 4000 8GB Win 11 Pro

HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2225 processor running at 4.1GHz with a 4.6GHz turbo frequency across four cores. It ships with 128GB of DDR4 2933 ECC registered memory in a 4x 32GB configuration and a 4TB PCIe NVMe solid-state drive. Professional graphics are provided by an Nvidia Quadro RTX 4000 with 8GB GDDR6 memory and a 256-bit interface. The system includes a 1000W 80 Plus Gold power supply and Windows 11 Pro.

Suits ISV-certified CAD and simulation.

This workstation suits engineers and designers who rely on ISV-certified stability for 3D CAD, rendering and visualisation tasks using a single professional GPU. The four-core Xeon and 128GB DDR4 2933 ECC memory handle large datasets and complex simulations within certified applications. Buyers who need multi-GPU scaling, higher core counts for distributed rendering or greater than 512GB maximum memory capacity should evaluate alternative platforms.

Verify PCIe slots and M.2 keying before adding

Before ordering, confirm that your planned expansion cards fit the available PCIe slot layout and that any additional M.2 drives match the supported keying and PCIe NVMe protocol. The 1000W 80 Plus Gold unit powers the factory configuration; calculate total draw if you intend to install additional high-power GPUs or storage devices. Ensure your display connectors match the Quadro RTX 4000 outputs of three DisplayPort 1.4 and one USB-C port.
