HP Z4 G4 Workstation Xeon W-2225 4.1GHz 256GB DDR4 2TB NVMe RTX 4000 8GB Windows 11 Pro

Workstation for compute-intensive workflows

The HP Z4 G4 is a new mid-tower desktop built around an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo frequency across four cores. It targets professionals who need certified reliability for 3D CAD, rendering, visualization and GPU-accelerated applications. The system ships with Windows 11 Pro pre-installed and activated. Buyers who require dual-processor scaling or higher core counts for massive simulations will need a different platform.

ECC memory and professional graphics connectivity

The chassis holds 256 GB of DDR4 2933 ECC registered memory configured as eight 32 GB modules, with capacity to reach 512 GB. A 2 TB M.2 PCIe NVMe drive provides primary storage, while internal bays and additional M.2 slots accept further SATA or NVMe drives. The NVIDIA Quadro RTX 4000 adds 8 GB of GDDR6 memory on a 256-bit bus and outputs through three DisplayPort 1.4 connectors and one USB-C graphics port. Integrated Gigabit Ethernet and high-definition audio handle networking and sound without add-in cards.

1000 W Gold power supply for sustained loads

An 80 Plus Gold certified 1000 W unit delivers 90 percent efficiency under typical loads, supporting the CPU, GPU and full memory population without headroom concerns. The mid-tower design uses toolless access for component swaps and maintenance. Acoustic profile and thermal behaviour are tuned for professional environments running continuous compute-intensive workloads. Builders who need redundant power supplies or rackmount form factors should consider other chassis options.
