Professional workstation for compute-intensive

The HP Z4 G4 mid-tower workstation delivers single-processor performance with an Intel Xeon W-2235 3.8GHz six-core processor reaching 4.6GHz turbo. It includes 16GB DDR4 2933 ECC registered memory and a 4TB NVMe SSD. The Nvidia Quadro RTX 5000 16GB GDDR6 256-bit graphics adapter provides four DisplayPort 1.4 outputs plus VirtualLink. Windows 11 Pro 64-bit is pre-installed.

Build integration with tool-less access

This mid-tower chassis offers tool-less entry for simple upgrades and maintenance. Multiple PCIe slots support additional professional graphics or I/O cards. Internal bays and M.2 slots accept combinations of SATA and PCIe NVMe drives for flexible storage scaling. Integrated Gigabit Ethernet and high-definition audio handle baseline connectivity. A monitor is not included and must be sourced separately.

Thermals and power with 1000W 80 Plus Gold supply

The included 1000W power supply operates at 90% efficiency under typical loads. The workstation is engineered and tested to meet industry reliability standards for sustained professional workloads. ISV certification with leading applications confirms stable operation during extended rendering, simulation and CAD sessions. Professional graphics certification ensures consistent thermal behaviour for GPU-accelerated tasks.

Questions about this item

What happens when the 1000W 80 Plus Gold PSU is loaded continuously by the Xeon W-2235 and Quadro RTX 5000?

The 1000W 80 Plus Gold supply runs at 90% efficiency under sustained loads, delivering stable power to the 6-core Xeon at 3.8GHz base and the RTX 5000 16GB GDDR6 without throttling.

How loud and hot does the mid-tower get when the Quadro RTX 5000 runs all-day rendering?

HP's thermal design uses a single 1000W Gold PSU and chassis airflow tuned for the RTX 5000 256-bit GPU, keeping noise and temperatures within workstation-class limits during extended GPU workloads.

Which displays and cables must I already own to use the four DP 1.4 outputs and VirtualLink port?

You need monitors with DisplayPort 1.4 inputs and matching cables for each of the four DP 1.4 connectors; VirtualLink requires a compatible USB-C display or headset with its own cable.
