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.

Questions about this item

What comes in the box and what must I buy separately?

The workstation includes the Xeon W-2223 processor, 16GB DDR4 2666 ECC memory (2x 8GB), 500GB M.2 NVMe SSD, Quadro RTX 4000 8GB GDDR6 graphics card with three DisplayPort 1.4 and one USB-C output, 1000W 80 Plus Gold power supply, and Windows 11 Pro. A monitor is not included.

Which memory capacity should I choose for this workstation?

The system ships with 16GB DDR4 2666 ECC registered memory and supports up to 512GB total. Choose 16GB for standard professional workflows; select higher capacities only if your applications regularly exceed the installed amount.

What does the 3.6GHz Xeon W-2223 speed mean in actual use?

The four-core Xeon W-2223 runs at a 3.6GHz base frequency and can reach 3.9GHz turbo when thermal headroom allows, delivering strong single-thread performance for CAD, simulation and rendering tasks inside this Z4 G4 chassis.
