HP Z4 G4 Business Desktop Xeon W-2223 3.6GHz 256GB DDR4 500GB NVMe Quadro RTX 4000 8GB Windows 11 Pro

Professional single-processor workstation

This HP Z4 G4 mid-tower workstation delivers Intel Xeon W-2223 performance with a 3.6 GHz base clock and 3.9 GHz turbo across four cores. It targets engineers, designers and analysts running compute-intensive professional applications that benefit from high single-thread speed and ISV-certified reliability. The 256 GB DDR4 2666 ECC registered memory and 500 GB NVMe SSD support large datasets and fast project loading out of the box.

Verify LGA 2066 platform and power budget

Confirm your existing infrastructure can accommodate an LGA 2066 socket motherboard and the 1000 W 80 Plus Gold power supply included with this unit. The mid-tower chassis requires adequate rack or desk depth for tool-less service access, and the Quadro RTX 4000 occupies a double-width PCIe slot with three DisplayPort 1.4 and one USB-C output. Ensure your display cables and monitor inputs match these connectors before deployment.

256 GB ECC memory and Quadro RTX 4000 change

Eight 32 GB DDR4 2666 ECC modules fill half the 512 GB maximum, leaving four slots open for future expansion without replacing existing sticks. The Quadro RTX 4000 adds 8 GB GDDR6 on a 256-bit bus, enabling GPU-accelerated 3D CAD, rendering and visualization workloads that integrated graphics cannot handle. Windows 11 Pro 64-bit digital activation is pre-installed, so the system is ready for domain join and enterprise management immediately.
