Professional Workstation Configuration

The HP Z4 G4 mid-tower workstation delivers single-processor performance for demanding professional workflows. It features an Intel Xeon W-2223 3.6GHz (3.9GHz Turbo) 4-core processor paired with 256GB DDR4 2666MHz ECC registered memory. A 2TB M.2 NVMe solid-state drive provides fast system responsiveness. An NVIDIA Quadro RTX 4000 8GB GDDR6 graphics adapter with four display outputs supports visualisation tasks. The system ships with Windows 11 Pro and a 1000W 80 Plus Gold power supply.

Suitability for Compute-Intensive Tasks

This configuration suits professionals running ISV-certified applications for 3D CAD, rendering and complex simulations that benefit from ECC memory reliability and professional GPU drivers. The 256GB memory capacity handles large datasets within the 512GB maximum supported limit. Buyers who need dual-processor scalability or higher core counts for heavily threaded workloads should evaluate alternative platforms. Users requiring consumer gaming features not validated on professional drivers should also look elsewhere.

Graphics Adapter Determines Display Connectivity

The single most decisive specification is the NVIDIA Quadro RTX 4000 8GB GDDR6 card with three DisplayPort 1.4 connectors and one USB-C output. This specific adapter dictates the number and type of displays supported directly from the workstation. It also defines the certified driver stack for professional visualisation software. Verify that your monitor connectivity and application certification requirements match this exact graphics configuration before purchase.

Questions about this item

Will my existing LGA 2066 Xeon W-2223 3.6GHz processor fit alongside this system's memory configuration?

The board accepts Xeon W-2223 and up to 512GB DDR4 2666 ECC registered memory; this unit already ships with 256GB in eight 32GB modules.

How can I verify the Nvidia Quadro RTX 4000 8GB GDDR6 is operating at full capability after installation?

Open NVIDIA Control Panel and confirm 3x DisplayPort 1.4 and USB-C outputs are detected; GPU-Z should show 4000 series name, 8GB VRAM and 256-bit bus width.

Does the box include any display cables or mounting brackets for the RTX 4000's three DisplayPort 1.4 and USB-C ports?

The workstation ships with power cord and HP 1000W 80 Plus Gold supply; display cables, monitor and any port adapters are purchased separately.
