Professional CAD workstation

The HP Z4 G4 is a new professional workstation built around an Intel Xeon W-2135 six-core processor running at 3.70GHz. It ships with 16GB of DDR4 memory and a 512GB solid-state drive. Windows 11 Pro comes pre-installed and the system includes a dedicated K4000 graphics card.

Suited for engineering and design workflows

This configuration suits engineers, designers and content creators who need responsive CPU performance and certified graphics drivers for CAD, rendering and data-heavy applications. The 16GB DDR4 baseline handles typical project files, while two 3.5-inch bays and an M.2 slot allow storage expansion. Buyers who need more memory capacity than 16GB out of the box or who require a different GPU class should look at other configurations.

Six-core Xeon W-2135 at 3.70GHz

The single specification that decides fit is the six-core Xeon W-2135 running at 3.70GHz, which determines the thread count and clock speed available for professional compute tasks. The platform supports up to 512GB of DDR4 memory across its slots. The dedicated K4000 GPU provides certified driver support for professional visualisation workloads.
