HP Z4 G4 Xeon workstation

The HP Z4 G4 is a tower workstation built around a single Intel Xeon W-2135 six-core processor running at 3.7GHz. It ships with 32GB of DDR4 ECC memory, a 500GB NVMe M.2 SSD, a 2TB 7.2K SATA drive and an NVIDIA Quadro P1000 graphics card with 4GB GDDR5. Windows 11 comes pre-installed for immediate professional use.

Compatibility checklist

Verify that your displays accept Mini DisplayPort 1.4 inputs because the Quadro P1000 provides four of those ports. The board has eight DDR4 ECC DIMM slots arranged in four channels; all 32GB are already installed so the memory limit of 32GB is reached. Two internal 3.5-inch bays and two external 5.25-inch bays are available for extra storage if the onboard SATA controller and RAID 0/1/5/10 support meet your needs.

Build and daily use

The tower chassis includes acoustic dampening rails on the 3.5-inch bays to reduce drive noise during long rendering sessions. A dedicated 9.5mm slim optical bay holds the DVD±RW drive without using a 5.25-inch slot. Dual LAN ports sit on the rear I/O alongside USB 2.0 and USB 3.1 Gen 1 ports, while Thunderbolt 3 and USB 3.1 Gen 2 remain optional upgrades. The 750W power supply feeds up to two PCI Express x16 Gen 3 graphics cards with appropriate power connectors.

Questions about this item

Does the HP Z4 G4 workstation include the NVIDIA Quadro P1000 graphics card and Windows 11, or must they be purchased separately?

The workstation ships with the NVIDIA Quadro P1000 4GB GDDR5 card installed and Windows 11 preinstalled, so no separate graphics card or operating-system purchase is required.

Should I choose the 500GB NVMe drive or the 2TB SATA drive as the primary boot volume for faster application loading?

Use the 500GB NVMe M.2 SSD as the boot drive; its NVMe interface delivers much quicker application and project-file access than the 2TB 7.2K SATA drive, which is better suited for bulk storage.

How does the Xeon W-2135 3.7GHz 6-core processor perform when running multi-threaded CAD rendering workloads in this tower?

The six-core Xeon W-2135 at 3.7GHz with 12 threads handles multi-threaded CAD rendering efficiently, and the four-channel DDR4-2666 ECC memory architecture keeps data flowing to all cores without bottlenecks.
