HP Z4 G4 Workstation Xeon W-2223 3.6GHz 16GB DDR4 500GB NVMe Quadro RTX 4000 8GB Windows 11 Pro

Built for professional workflows

The HP Z4 G4 workstation pairs an Intel Xeon W-2223 four-core processor at 3.6 GHz with a 3.9 GHz turbo boost and 16 GB of DDR4 2666 ECC registered memory. A 500 GB NVMe SSD provides fast boot and project loading while the NVIDIA Quadro RTX 4000 8 GB GDDR6 card drives up to four displays via three DisplayPort 1.4 outputs and one USB-C connector. A 1000 W 80 Plus Gold supply powers the mid-tower chassis running Windows 11 Pro.

Verify power and expansion needs

Confirm your facility can deliver sufficient mains current for the 1000 W power supply and that the mid-tower dimensions suit your rack or desk space. The LGA 2066 platform supports DDR4 2666 ECC registered modules up to 512 GB total capacity, so plan memory upgrades with matching speed and ECC type. Ensure any additional PCIe cards fit the available slot layout and that DisplayPort 1.4 or USB-C monitor cables match the Quadro outputs.

Replaces older single-socket towers

This system upgrades from earlier Xeon workstations limited to lower core counts, slower DDR4 speeds or smaller NVMe boot drives. The jump is worthwhile when ISV-certified stability, ECC memory integrity and Quadro RTX 4000 graphics acceleration are required for CAD, rendering or simulation workloads. Buyers needing dual-socket scaling or higher GPU memory should evaluate larger platforms.
