HP Z4 G4 Workstation Xeon W-2235 128GB 4TB NVMe RTX 4000 8GB Win 11 Pro

Professional Workstation for Demanding Workflows

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency across six cores. It ships with 128 GB of DDR4 2933 ECC registered memory in a four-module configuration and a 4 TB PCIe NVMe solid-state drive. An NVIDIA Quadro RTX 4000 graphics card with 8 GB of GDDR6 memory provides certified professional visualisation, and Windows 11 Pro is pre-installed for immediate deployment.

Upgrade Path from Entry Workstations

This system replaces older single-socket workstations limited to lower core counts, slower memory speeds or smaller NVMe capacities. The jump is justified when workflows require ECC memory integrity for large datasets, certified GPU drivers for 3D CAD or rendering, and a 1000 W 80 Plus Gold power supply that supports sustained high-load operation. Buyers needing more than 512 GB of total memory or multi-GPU configurations should evaluate larger chassis platforms.

Build Integration and Expansion

The LGA 2066 platform provides multiple PCIe slots for additional storage controllers, capture cards or specialised I/O. Four occupied DIMM slots leave room to reach the 512 GB maximum using higher-capacity modules. The 256-bit GPU drives up to three DisplayPort 1.4 monitors plus a USB-C display output. Integrated Gigabit Ethernet and high-definition audio handle baseline connectivity without add-in cards.
