Professional workstation for demanding tasks

The HP Z4 G4 is a professional workstation built for design, content creation, rendering, engineering and data-heavy applications. Its Intel Xeon W-2135 six-core processor runs at 3.70GHz to deliver responsive performance for demanding professional workloads. The system includes 16GB of DDR4 memory and a dedicated K4000 graphics card. Windows 11 Pro comes pre-installed for immediate setup.

Upgrade from older workstations

This unit replaces ageing workstations that struggle with modern professional software and multitasking demands. The jump is worthwhile when your current machine lacks enough memory bandwidth or GPU acceleration for larger project files. The 1TB hard drive provides capacity for everyday professional work, while the 512GB maximum memory ceiling allows future expansion. Buyers who need more than two 3.5-inch drive bays or a different GPU configuration should look elsewhere.

Check compatibility before ordering

Verify that your workflow fits within the two 3.5-inch expansion bays and single M.2 slot provided. Confirm that your applications run on Windows 11 Pro and do not require memory types other than DDR4. The 55kg weight means you must plan for suitable desk space and handling. Ensure your environment can accommodate the physical dimensions and power requirements of a full-size tower workstation.
