HP Z4 G4 Workstation for Professional Compute

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor with six cores running at 3.8GHz and a 4.6GHz turbo frequency. It ships with 64GB of DDR4 2933 ECC registered memory configured as four 16GB modules and a 1TB PCIe NVMe solid-state drive. Windows 11 Pro is pre-installed and activated.

Suits ISV-Certified Workloads.

This workstation suits engineers, designers and analysts who rely on ISV-certified stability for CAD, rendering and simulation tasks using a single professional graphics card. The integrated Quadro P2000 provides 5GB of GDDR5 memory on a 160-bit bus with four DisplayPort 1.4 outputs for multi-display setups. Buyers who need more GPU memory for large models, multiple graphics cards for compute scaling, or consumer-grade gaming features should look at other configurations.

Quadro P2000 5GB GDDR5 Decides Fit

The installed Nvidia Quadro P2000 with 5GB GDDR5 VRAM is the specification that determines whether this system meets a given visualisation workload. Its four DisplayPort 1.4 connectors drive up to four native displays directly from the card. If a project requires larger frame buffers, higher memory bandwidth or certified drivers for applications not validated on this GPU class, the workstation will not be suitable.

Questions about this item

How do I verify the Xeon W-2235 reaches its 4.6GHz Turbo frequency under load?

Open Task Manager Performance tab or a monitoring utility and confirm the CPU clock hits 4.6GHz while running a multi-threaded workload; the 6-core processor is rated for that maximum turbo.

Which components are included and which must be purchased separately?

The workstation ships with the mid-tower chassis, Xeon W-2235 processor, four 16GB DDR4 2933 ECC Registered DIMMs, 1TB M.2 NVMe SSD, Quadro P2000 5GB GDDR5 card with four DP 1.4 outputs, 1000W 80 Plus Gold PSU and Windows 11 Pro; a monitor is not included.

Should I choose the 64GB configuration or plan to expand toward the 512GB maximum?

The 64GB (4x16GB) DDR4 2933 ECC Registered kit fills four slots; if your workloads regularly exceed that capacity, add matching ECC Registered modules up to the 512GB limit supported by the Xeon platform.
