Professional Single-Processor Workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2235 six-core processor running at 3.8GHz with a 4.6GHz turbo frequency. It targets engineers and content creators who need certified application stability and ECC memory integrity for compute-intensive professional workflows.

Mid-Tower Build Integration

The chassis provides multiple internal storage bays and M.2 slots for combining SATA and PCIe NVMe drives alongside the installed 2TB NVMe SSD. Four occupied DDR4 2933MHz slots leave room to expand toward the 512GB maximum, while toolless access simplifies hardware upgrades and maintenance inside the mid-tower frame.

Certified Graphics and Power Foundation

The Nvidia Quadro P2000 delivers 5GB GDDR5 memory on a 160-bit bus with four DisplayPort 1.4 outputs for multi-display visualisation tasks. A 1000W 80 Plus Gold power supply rated at 90% efficiency supports the graphics card and future expansion cards through the available PCIe slots.
