Workstation for professional workloads

The HP Z2 G4 mid-tower is built for engineers, designers and analysts who need certified professional graphics and reliable 9th-generation Intel Core processing. Its Quadro RTX 4000 card with 8GB GDDR6 memory drives multi-display visualisation across three DisplayPort 1.4 outputs and one USB-C connector. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Verify power, memory slots and drive bays

Confirm your facility can supply a grounded outlet for the internal 500W 90% efficient power supply before ordering. The board provides four DDR4 2666 unbuffered DIMM slots populated with 32GB today and supports up to 128GB total. The 500GB M.2 NVMe SSD occupies one M.2 slot; check remaining M.2 and 3.5-inch bays if you plan additional storage.

Sustained thermal performance under load

The mid-tower chassis and 500W 90% efficient power supply are designed to maintain stable clocks during extended rendering, simulation or compute sessions. Quadro drivers optimise the RTX 4000 for continuous professional workloads rather than short gaming bursts. Integrated Intel I219-LM Gigabit Ethernet and Conexant 5.1 audio remain active without throttling during long operations.

Questions about this item

Does the box include a monitor, keyboard or mouse, or must they be purchased separately?

The unit ships without a monitor, keyboard or mouse; all three peripherals must be bought separately.

Should I choose the 32 GB DDR4 2666 configuration or plan for more memory later?

The system arrives with 32 GB (4×8 GB) DDR4 2666 installed and supports up to 128 GB, so you can add modules later if workloads grow.

What does the Quadro RTX 4000 8 GB GDDR6 256-bit GPU deliver in daily workstation tasks?

The card provides 8 GB GDDR6 on a 256-bit bus with three DisplayPort 1.4 outputs and one USB-C video port for multi-display professional workflows.
