HP Z4 G4 Workstation Xeon W-2223

This new HP Z4 G4 mid-tower workstation is built for professional compute tasks. It runs an Intel Xeon W-2223 3.6 GHz processor with 3.9 GHz turbo across four cores. The system includes 256 GB of DDR4 2666 ECC registered memory and a 1 TB PCIe NVMe SSD. An Nvidia Quadro RTX 5000 with 16 GB GDDR6 drives graphics workloads. Windows 11 Pro is pre-installed.

Suits 3D CAD rendering and simulation

This configuration fits engineers running certified ISV applications that demand ECC memory stability and professional GPU drivers. The 1000 W 80 Plus Gold supply supports the installed Quadro RTX 5000. Buyers who need more than four CPU cores for heavy parallel compilation should consider other options. Users requiring more than 256 GB of RAM must add modules up to the 512 GB limit.

256 GB DDR4 2666 ECC registered memory

The workstation ships with eight 32 GB DDR4 2666 ECC registered DIMMs filling the available slots. This capacity and speed combination determines how large a dataset fits in fast memory without paging. Expanding to the 512 GB maximum requires replacing existing modules with higher-density parts. Confirm your application benefits from ECC before purchasing.

Questions about this item

What limits sustained performance of the Xeon W-2223 processor?

The four-core Xeon W-2223 runs at a 3.6 GHz base frequency and a 3.9 GHz turbo frequency, so prolonged all-core workloads are capped by the 3.6 GHz sustained speed and the 1000 W 80 Plus Gold power supply thermal envelope.

How loud or hot does the workstation get during all-day rendering?

The 1000 W 80 Plus Gold power supply runs at 90 % efficiency, reducing waste heat, while the mid-tower chassis uses tool-less airflow paths to keep the Quadro RTX 5000 and Xeon W-2223 within thermal limits during continuous loads.

Which displays can I connect to the Quadro RTX 5000 without extra adapters?

The Quadro RTX 5000 provides four DisplayPort 1.4 outputs and one VirtualLink connector, supporting up to four 8K or 5K monitors directly from the graphics card.
