HP Z4 G4 Mid-Tower Workstation Xeon W-2235 64GB DDR4 4TB NVMe Quadro RTX 4000 8GB Windows 11 Pro

Professional Workstation for Demanding Workflows

This HP Z4 G4 mid-tower workstation is built for professionals who need reliable single-processor performance. It ships with an Intel Xeon W-2235 6-core processor running at 3.8GHz with a 4.6GHz turbo frequency. The system includes 64GB of DDR4 2933 ECC registered memory configured as four 16GB modules. A 4TB PCIe NVMe SSD and NVIDIA Quadro RTX 4000 graphics card with 8GB GDDR6 memory complete the core specification.

Upgrading from Older Z Workstations

This configuration replaces earlier Z4 models or standard business desktops that cannot handle large datasets or GPU-accelerated workloads. The jump is worth it when your current machine hits memory limits, storage bottlenecks or lacks ISV-certified graphics for 3D CAD and rendering applications. The 512GB maximum memory capacity provides headroom for future expansion. The 1000W 80 Plus Gold power supply supports the installed Quadro RTX 4000 and additional internal components.

Verify Your Workflow Requirements

Before ordering, confirm that your professional applications benefit from ECC registered memory and ISV-certified Quadro drivers. The workstation provides three DisplayPort 1.4 outputs and one USB-C graphics connector for display connectivity. Integrated Gigabit Ethernet and high-definition audio are included on the motherboard. Ensure your monitors and peripherals match the available video outputs and that your workload fits within a single-socket Xeon platform.
