Professional workstation for demanding workflows

The HP Z4 G4 mid-tower workstation is built for professionals who need reliable single-processor performance for compute-intensive applications. It ships new with Windows 11 Pro and includes a 1000W 80 Plus Gold power supply. This system is not for buyers who require dual-processor configurations or more than four CPU cores.

Intel Xeon W-2225 processor with four cores

The installed Intel Xeon W-2225 runs at 4.1GHz with a 4.6GHz turbo frequency across its four cores on the LGA 2066 socket. Memory capacity is 64GB of DDR4 2933 ECC registered RAM in a 4x 16GB configuration, expandable to 512GB. The 1TB PCIe NVMe SSD provides fast system storage for large datasets.

Nvidia Quadro P5000 graphics with 16GB GDDR5X

Professional visualisation is handled by the Nvidia Quadro P5000 with 16GB GDDR5X memory on a 256-bit bus and four DisplayPort 1.4 outputs plus DVI-D DL. The 1000W 80 Plus Gold power supply delivers 90% efficiency to support the GPU and system components under load. Integrated Gigabit Ethernet and high-definition audio are included on the motherboard.

Questions about this item

What does the 4.1 GHz base and 4.6 GHz turbo mean for real workloads?

The Xeon W-2225 runs at 4.1 GHz on all four cores and can lift a single core to 4.6 GHz when thermal headroom allows, giving strong single-thread speed for CAD and simulation tasks.

How does the PCIe 3.0 x16 slot limit the Quadro P5000?

The card uses a PCIe 3.0 x16 link, so its 256-bit GDDR5X memory bandwidth stays inside the GPU; the slot does not throttle the 16 GB frame buffer or the four DisplayPort 1.4 outputs.

Will a 1000 W 80 Plus Gold supply fit in the mid-tower chassis?

Yes, the chassis is built around that 1000 W 80 Plus Gold unit with toolless access, so the power supply is already installed and matched to the case.
