HP Z4 G4 Workstation Overview

The HP Z4 G4 is a mid-tower workstation built for professional workloads. It ships with an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. The system includes 256 GB of DDR4 2933 ECC registered memory across eight 32 GB modules. A 1 TB PCIe NVMe SSD and an NVIDIA Quadro P5000 16 GB graphics card complete the core configuration.

Suits CAD and Simulation Users Not Multi GPU

This workstation suits engineers and designers running certified ISV applications for 3D CAD, rendering and GPU-accelerated compute. The single-processor LGA 2066 platform and 1000 W 80 Plus Gold power supply support the included Quadro P5000 and large memory capacity. Buyers who need dual-processor scaling or multiple high-end graphics cards should look at a different platform.

256 GB DDR4 2933 ECC Memory Decides Fit

The installed 256 GB of DDR4 2933 ECC registered memory is the key specification for handling large datasets and complex simulations. The board supports a maximum of 512 GB, so this configuration leaves room for future expansion. If your workflow demands more than 512 GB total memory capacity, this system will not meet that requirement.

Questions about this item

Should I choose the 256GB DDR4 2933 configuration or plan for the 512GB maximum?

The workstation ships with 256GB DDR4 2933 ECC registered memory installed as eight 32GB modules. The platform supports up to 512GB total, so you can add more later if workloads demand it.

What does the Xeon W-2235 3.8GHz 4.6GHz Turbo 6 core processor deliver for daily tasks?

The six-core Xeon W-2235 runs at a 3.8GHz base clock and can boost to 4.6GHz Turbo, giving strong single-thread responsiveness and multi-thread throughput for CAD, simulation and rendering workloads.

How does the PCIe NVMe interface affect the 1TB SSD speed in this system?

The 1TB drive uses a PCIe NVMe connection, providing fast sequential read and write performance for quick boot, application launch and large project file access.
