HP Z4 G4 Workstation Xeon W-2123 Quadro P400 8GB RAM No HDD

HP Z4 G4 Workstation | Xeon W-2123 | NVIDIA Quadro P400

The HP Z4 G4 is the world’s best-selling performance workstation, engineered to provide a rock-solid foundation for the 2026 demands of professional engineering and development. This configuration features the Intel Xeon W-2123, a high-frequency quad-core processor (3.60 GHz base) designed specifically for single-threaded performance in CAD applications and stable compute in Linux server environments.

Equipped with 16GB of DDR4 ECC RAM and the NVIDIA Quadro P400, the Z4 G4 is a high-reliability "workhorse" capable of handling 2D/3D modeling, software compilation, and dedicated dev-ops testing with enterprise-grade stability.

Key Performance Features

• High-Frequency Xeon Architecture: The Xeon W-2123 is optimized for workflows where clock speed is more critical than core count (such as AutoCAD or SolidWorks), while maintaining the reliability of ECC (Error Correction Code) memory support.

• NVIDIA Quadro P400 Graphics: A professional-grade GPU designed for reliability and driver stability. It provides a crisp, multi-monitor output (Mini DisplayPort) optimized for professional software suites rather than consumer gaming.

• Front-to-Back Airflow: The Z4 G4’s legendary chassis design features a sophisticated internal layout that keeps the CPU and memory cool under heavy thermal loads, ensuring the system doesn't throttle during long render or compile times.

• Security & Manageability: Includes HP’s suite of security features, including Sure Start (self-healing BIOS) and a TPM 2.0 module, making it fully compliant with modern corporate IT and government security standards.

• Tool-Less Serviceability: The interior is designed for rapid upgrades. Changing the power supply, adding RAM, or installing additional PCIe cards can be done in seconds without specialized tools.
