HP Z4 G4 Workstation Xeon W-2225 4.1GHz 64GB DDR4 4TB NVMe RTX 4000 8GB Windows 11 Pro

Professional Workstation for Compute-Intensive Tasks

The HP Z4 G4 mid-tower workstation targets professionals who need single-processor performance for demanding workflows. It ships with an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo frequency across four cores. The system includes 64 GB of DDR4 2933 ECC registered memory in a four-by-16 GB configuration. A 4 TB PCIe NVMe solid-state drive provides primary storage capacity.

Thermals Power and Acoustics

A 1000 W power supply rated at 80 Plus Gold with 90 percent efficiency delivers power to the components. The professional chassis design manages thermal output from the Xeon processor and the Nvidia Quadro RTX 4000 graphics card with 8 GB GDDR6 memory. Integrated cooling solutions maintain stable operation during sustained compute-intensive workloads. The power supply efficiency rating supports consistent delivery under load.

Build Connectivity and Expandability

The mid-tower form factor offers toolless access to internal components for simpler upgrades and maintenance. Graphics connectivity includes three DisplayPort 1.4 outputs and one USB-C port on the Quadro RTX 4000 adapter. The motherboard uses an LGA 2066 socket and supports up to 512 GB of DDR4 memory across available slots.
