Professional workstation for compute-intensive

The HP Z4 G4 workstation targets engineers and designers who need certified single-processor performance for 3D CAD, rendering and GPU-accelerated applications. It ships with Windows 11 Pro and an Intel Xeon W-2223 3.6GHz processor reaching 3.9GHz Turbo across four cores.

16GB ECC memory and RTX 5000 GPU change daily

Sixteen gigabytes of DDR4 2666 ECC registered memory in a 2×8 GB layout provides error correction for large datasets. The Nvidia Quadro RTX 5000 adds 16GB GDDR6 on a 256-bit bus with four DisplayPort 1.4 outputs plus VirtualLink, enabling multi-display visualisation without a separate graphics purchase.

Tool-less chassis simplifies upgrades.

The mid-tower chassis offers toolless access to internal components and multiple PCIe slots for expansion. A 1000W 80 Plus Gold power supply delivers 90% efficiency headroom. Maximum supported memory is 512 GB DDR42933, so buyers planning heavier workloads must add modules later.

Questions about this item

Will the 16 GB DDR4 2666 ECC memory need replacement and how much can I add?

The workstation ships with 16 GB DDR4 2666 ECC registered memory in two 8 GB modules and supports up to 512 GB total, so you can expand later without replacing the original sticks.

What limits sustained performance first on the Xeon W-2223 3.6 GHz 4-core processor?

Under continuous load the 4-core Xeon W-2223 hits its 3.9 GHz turbo ceiling and thermal envelope before the 1000 W 80 Plus Gold supply or the Quadro RTX 5000 16 GB GDDR6 become bottlenecks.

How loud and hot does the system get when the Quadro RTX 5000 16 GB runs all day?

The 1000 W 80 Plus Gold power supply runs at 90 % efficiency, keeping waste heat low, while the mid-tower chassis uses tool-less airflow paths to move heat from the GPU and CPU during extended sessions.
