Professional workstation for design and engineering

The HP Z2 G4 mid-tower combines an Intel Core i5-9500 six-core processor with an NVIDIA Quadro RTX 4000 8GB GDDR6 graphics card. Sixteen gigabytes of DDR4 2666 memory and a 2TB NVMe SSD provide responsive throughput for CAD, rendering and simulation workloads. Windows 11 Pro is pre-installed and digitally activated.

Standard mid-tower access with certified drivers

The chassis opens without tools for memory, storage and graphics upgrades up to the 128GB DDR4 limit. Quadro RTX 4000 drivers are validated for major ISV applications, reducing configuration errors. The 500W 90% efficient power supply uses standard ATX connectors, so cable routing follows familiar patterns.

Sustained compute and graphics throughput

The i5-9500 maintains its 3.0GHz base clock under continuous multi-threaded loads with a 4.4GHz single-core turbo for burst tasks. Quadro RTX 4000 8GB frame buffer and 256-bit memory bus keep large assemblies resident during long render passes. Integrated Intel I219-LM gigabit Ethernet and 5.1 high-definition audio remain stable during extended sessions.

Questions about this item

How can I verify the Intel Core i5-9500 is running at its 4.4GHz turbo speed after setup?

Open Task Manager's Performance tab or use a tool like HWMonitor to watch the CPU clock under load; the 6-core processor should hit 4.4 GHz when thermal headroom allows.

What comes in the box and what must I buy separately to get video output?

The workstation, power cord and Windows 11 Pro licence are included; a monitor and DisplayPort or USB-C cables are not, so purchase those to connect the Quadro RTX 4000's three DP 1.4 ports and USB-C output.

Should I choose the 16 GB DDR4 2666 configuration or upgrade toward the 128 GB maximum for rendering workloads?

The installed 16 GB (2×8 GB) suits many CAD tasks; if you regularly handle large assemblies or GPU compute queues, add matching DDR4 2666 modules up to the 128 GB limit.
