Professional tower workstation

The HP Z4 G4 is a new tower workstation built for professional design, engineering and content-creation tasks. A six-core Xeon W-2135 at 3.7 GHz and 32 GB of DDR4 ECC memory deliver stable performance for CAD, rendering and data-heavy applications. Windows 11 is preinstalled for immediate use.

Suited for single-threaded professional apps

This system suits users who need certified Quadro graphics and ECC memory for 3D modelling, simulation or multi-display workflows. Buyers who want more storage than the 250 GB NVMe drive provides, or who require dual-processor scaling, should look at a different platform. The four Mini DisplayPort 1.4 outputs support up to four monitors.

Memory fixed at 32 GB

The workstation arrives with 32 GB of DDR4 ECC installed and the specification lists the maximum capacity as 32 GB, so no further memory upgrades are possible. This limit decides whether the Z4 G4 can handle your largest datasets and multitasking needs.
