HP Z4 G4 Workstation for Professional Compute

This new HP Z4 G4 mid-tower workstation pairs an Intel Xeon W-2225 4-core processor running at 4.1GHz with 4.6GHz turbo, 16GB of DDR4 2933 ECC registered memory, a 2TB NVMe SSD and an NVIDIA Quadro RTX 4000 8GB GDDR6 graphics card. Windows 11 Pro is pre-installed and the system is powered by a 1000W 80 Plus Gold supply. It is built for engineers, designers and analysts who need certified single-processor performance for CAD, rendering and simulation workloads.

Who This Suits and Who Should Look Elsewhere

Buyers who need ISV-certified reliability, ECC memory integrity and professional graphics drivers for 3D CAD, visualization or GPU-accelerated applications will find this configuration aligned with those requirements. Teams that require dual-processor scaling, higher core counts than the four provided by the W-2225, or greater than 16GB of memory out of the box should evaluate alternative platforms.

Deciding Specification: 4-Core Xeon W-2225

The Xeon W-2225 delivers four cores at a 4.1GHz base frequency with 4.6GHz turbo, setting the ceiling for single-thread throughput and total parallel capacity in this chassis. If your workloads demand more simultaneous threads or a higher base frequency than this processor provides, the system will not meet the performance target regardless of the graphics or storage configuration.
