HP Z2 G4 Mid-Tower Workstation

The HP Z2 G4 is a mid-tower workstation built around an Intel Core i5-9500 6-core processor with 4.4GHz turbo. It ships with 128GB DDR4 2666 memory in a 4x 32GB configuration and a 500GB NVMe SSD. An NVIDIA Quadro P4000 8GB GDDR5 graphics card provides four DisplayPort 1.4 outputs for multi-display professional setups. Windows 11 Pro is pre-installed and activated.

Who this suits and who should look elsewhere

This system suits professionals running CAD, BIM or simulation workloads that benefit from certified Quadro drivers and large memory capacity. The four DisplayPort 1.4 connectors drive multiple high-resolution monitors without adapters. Buyers who need ECC memory for data integrity or a GPU with more than 8GB frame buffer for large datasets should consider other configurations. The LGA 1151 platform limits future CPU upgrades to 9th generation Intel Core processors.

Quadro P4000 8GB GDDR5 graphics

The NVIDIA Quadro P4000 delivers 8GB GDDR5 memory on a 256-bit bus with four native DisplayPort 1.4 outputs. It is certified for major ISV applications including SolidWorks, AutoCAD and Revit. The card occupies a single double-width slot and draws power from the internal 500W 90% efficient supply. This GPU specification determines whether the workstation meets the graphics memory and driver certification requirements of your professional software.

Questions about this item

How do I choose between the listed memory and storage capacities for this workstation?

This unit ships with 128GB DDR4 2666 memory in a 4 x 32GB configuration and a 500GB M.2 NVMe SSD; both are already at the platform maximums so no selection is needed.

What does the 4.4GHz turbo figure mean for real workloads on the i5-9500?

The Intel Core i5-9500 can boost from its 3.0GHz base to 4.4GHz on active cores, giving short bursts of higher single-thread speed for CAD or simulation tasks before thermal limits settle it back toward base clocks.

What does the Quadro P4000 256-bit GDDR5 interface cap in practice?

The 256-bit GDDR5 memory bus on the Quadro P4000 delivers up to 256 GB/s bandwidth, which caps texture and frame-buffer throughput for 4x DisplayPort 1.4 outputs in professional 3D and video workflows.
