Professional Workstation for Compute-Intensive

The HP Z4 G4 Mid-Tower Workstation is built for professionals who need reliable single-processor performance in demanding applications such as 3D CAD, rendering and large-dataset simulations. It ships with Windows 11 Pro and a 1000W 80 Plus Gold power supply. This system is not suited for buyers who require dual-processor scaling or server-grade redundancy.

Xeon W-2225 Four-Core Processor with 4.6GHz Turbo

The decisive specification is the Intel Xeon W-2225 CPU running at 4.1GHz base clock and reaching 4.6GHz Turbo on four cores, installed in an LGA 2066 socket. It is paired with 64GB of DDR4 2933 ECC Registered Memory across four 16GB modules, expandable to 512GB. Builders who need higher core counts or a different socket should consider other configurations.

Quadro P5000 16GB GDDR5X with 1000W Gold Supply

The Nvidia Quadro P5000 provides 16GB of GDDR5X memory on a 256-bit bus and drives up to four DisplayPort 1.4 outputs plus a dual-link DVI-D connector. The integrated 1000W 80 Plus Gold unit delivers 90% efficiency to support the GPU and storage under sustained load. Users seeking lower acoustic output or a smaller power envelope will need a different platform.

Questions about this item

How does the 4.6GHz turbo frequency behave when the Xeon W-2225 is installed in this Z4 G4 chassis?

The processor can reach 4.6GHz turbo on active cores while the 1000W 80 Plus Gold supply and mid-tower cooling maintain stable operation under sustained professional workloads.

What does the Quadro P5000 256-bit GDDR5X interface deliver for display output?

The 256-bit memory bus feeds four DisplayPort 1.4 connectors and one dual-link DVI-D, driving multiple 4K or 5K monitors simultaneously for CAD and visualisation tasks.

What physical space and power does the Quadro P5000 require inside the mid-tower case?

The full-height, dual-slot card occupies one PCIe x16 slot and draws power from the 1000W 80 Plus Gold unit via its onboard connectors, with tool-less access for installation.
