HP Z4 G4 Workstation Xeon W-2223 3.6GHz 64GB DDR4 1TB NVMe RTX 5000 16GB Windows 11 Pro

Professional Single-Processor Workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2223 processor running at 3.6GHz with a 3.9GHz turbo frequency across four cores. It ships with 64GB of DDR4 2666MHz ECC registered memory in a four-module configuration and a 1TB PCIe NVMe solid-state drive. An Nvidia Quadro RTX 5000 graphics card with 16GB GDDR6 memory on a 256-bit bus provides four DisplayPort 1.4 outputs and a VirtualLink connector. Windows 11 Pro is pre-installed and digitally activated.

Suited for ISV-Certified Professional Applications

This system targets engineers, designers and analysts running certified 3D CAD, rendering, visualization and GPU-accelerated workloads that rely on ECC memory and professional driver stacks. The 1000W 80 Plus Gold power supply and multiple PCIe slots support internal expansion for additional storage or specialised add-in cards. Buyers who need dual-processor throughput, higher core counts per socket or greater than 512GB maximum memory capacity should evaluate alternative platforms.

Factory-Configured Memory, Storage and Graphics

The 64GB DDR4 2666 ECC kit occupies four DIMM slots, leaving room to scale toward the 512GB ceiling supported by the Xeon W architecture. The 1TB M.2 NVMe drive delivers fast system responsiveness while SATA bays remain available for high-capacity project storage. The pre-installed RTX 5000 16GB card is validated for ISV applications, removing the need for separate graphics procurement and driver qualification. Tool-less chassis access simplifies future upgrades to memory, storage or expansion cards.
