HP Z4 G4 Workstation for Demanding Workflows

This HP Z4 G4 mid-tower workstation delivers professional single-processor performance for compute-intensive applications. It features an Intel Xeon W-2235 6-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. The system includes 128 GB of DDR4 2933 ECC registered memory in a 4x 32 GB configuration. A 1 TB PCIe NVMe SSD provides fast system responsiveness.

Suits CAD and Visualisation Professionals

This configuration suits engineers and designers running 3D CAD, rendering and GPU-accelerated workloads on ISV-certified hardware. The Nvidia Quadro RTX 5000 with 16 GB GDDR6 memory drives up to four DisplayPort 1.4 monitors. Buyers who need multi-processor scaling or more than 512 GB of memory should look at a different platform.

Deciding Specification: Nvidia Quadro RTX 5000 16 GB

The Quadro RTX 5000 16 GB graphics card is the specification that determines whether this workstation fits the workload. Its 256-bit memory interface and certified drivers target professional visualisation and simulation tasks. If the workload does not require certified professional graphics, a different system may be more appropriate.

Questions about this item

How can I confirm the Xeon W-2235 is hitting its 4.6GHz Turbo frequency under load?

Open Task Manager or a hardware monitor and watch the CPU clock while running a heavy render or simulation; the six-core processor should show speeds up to 4.6GHz when thermals allow.

What cables or adapters must I supply to connect the Quadro RTX 5000 to my displays?

The card provides four DisplayPort 1.4 outputs and one VirtualLink port, so you only need DisplayPort cables or DP-to-HDMI adapters for your monitors.

Which memory configuration should I choose if I want to expand beyond the installed 128GB?

The workstation uses four 32GB DDR4 2933 ECC Registered modules; free DIMM slots support up to 512GB total with matching ECC RDIMMs.
