HP Z4 G4 Workstation Xeon W-2223 3.6GHz 256GB DDR4 4TB NVMe Quadro P5000 16GB

Professional Workstation Build

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2223 processor with four cores running at 3.6GHz and a 3.9GHz turbo frequency. It ships with 256GB of DDR4 2666 ECC registered memory configured as eight 32GB modules. A 4TB PCIe NVMe solid-state drive provides primary storage, while an Nvidia Quadro P5000 graphics card with 16GB GDDR5X memory drives four DisplayPort 1.4 outputs and one dual-link DVI-D port. The system includes a 1000W 80 Plus Gold power supply and Windows 11 Pro.

Suited For Specialised Workloads

This configuration targets engineers, designers and analysts running ISV-certified applications that demand ECC memory integrity and professional GPU drivers. The 256GB memory capacity supports large datasets and complex simulations within the 512GB maximum supported limit. Buyers who need more than four CPU cores, higher memory bandwidth than DDR4 2666 provides, or graphics memory beyond 16GB should evaluate alternative configurations. The mid-tower form factor also limits the number of full-length add-in cards compared to larger chassis.

The Deciding Specification

The Xeon W-2223 processor uses the LGA 2066 socket and delivers four cores at 3.6GHz base clock with 3.9GHz turbo. This core count defines the workstation's throughput ceiling for both single-threaded CAD operations and lightly threaded simulation tasks. If your software licenses scale poorly beyond four cores, this CPU avoids paying for unused silicon. If your solvers scale efficiently across eight or more cores, the four-core limit becomes the bottleneck regardless of memory or storage speed.
