HP Z4 G4 Business Desktop Xeon W-2235 128GB 4TB NVMe Quadro P5000 16GB Windows 11 Pro

Professional workstation for compute-intensive

The HP Z4 G4 is a new mid-tower business desktop built around an Intel Xeon W-2235 processor with 6 cores running at 3.8 GHz and a 4.6 GHz turbo frequency. It ships with 128 GB of DDR4 2933 ECC registered memory in a 4 x 32 GB configuration and a 4 TB PCIe NVMe solid-state drive. An Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory and a 256-bit interface drives professional visualisation workloads. Windows 11 Pro is pre-installed and digitally activated.

Tool-free chassis with professional I/O

The black mid-tower enclosure uses a tool-less design for straightforward access to internal components. The Quadro P5000 provides four DisplayPort 1.4 outputs and one dual-link DVI-D connector for multi-display setups. Integrated Gigabit Ethernet and high-definition audio handle networking and sound without add-in cards. A 1000 W 80 Plus Gold power supply rated at 90 % efficiency delivers stable power to the CPU, memory and graphics subsystem.

Verify memory, storage and slot requirements

This system uses DDR4 2933 ECC registered DIMMs; confirm that any additional modules match this specification before ordering. The motherboard supports a maximum of 512 GB across its available slots. The 4 TB boot drive occupies an M.2 NVMe slot; check remaining M.2 and SATA bays if you plan to add further storage. Ensure your displays use DisplayPort 1.4 or dual-link DVI-D inputs to match the graphics card outputs.
