HP Z4 G4 Workstation Xeon W-2235 32GB 1TB NVMe RTX 5000 16GB Win11 Pro

Workstation for professional compute

The HP Z4 G4 Mid-Tower is a new business desktop built around an Intel Xeon W-2235 processor with six cores running at 3.8 GHz and a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory in a four-module configuration. A 1 TB PCIe NVMe SSD provides the primary storage, while an NVIDIA Quadro RTX 5000 graphics card with 16 GB of GDDR6 memory drives up to four DisplayPort 1.4 outputs and a VirtualLink connector. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Verify power and expansion needs

The chassis uses a mid-tower form factor with an LGA 2066 socket motherboard supporting up to 512 GB of DDR4 memory across its slots. A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency is fitted as standard. Buyers should confirm that the available PCIe slots and physical clearance match any additional cards they intend to install. Integrated gigabit ethernet and high-definition audio are provided on the motherboard.

Thermals and power in daily use

The 1000 W gold-rated supply delivers headroom for the Xeon CPU and the RTX 5000 GPU under sustained professional workloads. System fans are managed by the workstation firmware to balance airflow against acoustic output during rendering or simulation tasks. Power draw will scale with compute intensity, and the 90 percent efficient supply helps reduce waste heat at the wall. No liquid cooling or exotic thermal hardware is mentioned in the specifications.
