HP Z4 G4 Workstation Xeon W-2235 64GB DDR4 2TB NVMe RTX 4000 8GB Windows 11 Pro

Professional workstation for compute-intensive

The HP Z4 G4 Mid-Tower Workstation is built for professionals who need reliable single-processor performance for demanding applications such as 3D CAD, rendering and complex simulations. It ships with an Intel Xeon W-2235 3.8GHz (4.6GHz Turbo) 6 Core Processor, 64GB DDR4 2933MHz ECC Registered Memory, a 2TB M.2 NVMe Solid State Drive and an Nvidia Quadro RTX 4000 8GB GDDR6 graphics card. Windows 11 Pro is pre-installed and digitally activated.

Sustained-load behaviour

The 1000W 80 Plus Gold 90% efficient power supply delivers stable energy to the 6-core Xeon W-2235 and Quadro RTX 4000 during extended rendering or simulation tasks. Four 16GB DDR4 2933 ECC modules provide error-correcting memory that maintains data integrity over long compute sessions. The mid-tower chassis uses tool-less access for thermal management, while the PCIe NVMe drive keeps project assets feeding the GPU without bottlenecks.

Verify PCIe slots, M.2 keying

This unit includes three DisplayPort 1.4 outputs and one USB-C graphics connector on the Quadro RTX 4000; confirm your monitors match these interfaces. The motherboard uses an LGA 2066 socket and supports up to 512 GB DDR4 2933 ECC across multiple slots, so check available DIMM slots if you plan to expand beyond the factory 64GB. Internal storage bays and M.2 slots accept SATA and PCIe NVMe drives, but verify the M.2 key type required for your additional drives.
