HP Z2 G4 Workstation i5-9500 64GB 2TB NVMe RTX 4000 Windows 11 Pro

Z2 G4 mid-tower workstation

The HP Z2 G4 is a mid-tower desktop workstation built around a 3.0 GHz Intel Core i5-9500 six-core processor that can reach 4.4 GHz turbo. It ships with 64 GB of DDR4 2666 memory in a four-by-16 GB configuration and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro RTX 4000 graphics card with 8 GB of GDDR6 memory on a 256-bit bus drives professional visual workloads. Windows 11 Pro 64-bit is pre-installed and digitally activated.

500 W 90 % supply and expandable memory

A 500-watt power supply rated at 90 percent efficiency powers the CPU, GPU, memory and storage without requiring an external brick. The LGA 1151 platform supports up to 128 GB of DDR4, leaving two DIMM slots free for future expansion. Integrated Intel I219-LM gigabit Ethernet and Conexant CX20632 5.1 high-definition audio handle networking and sound without add-in cards. Three DisplayPort 1.4 outputs and one USB-C connector on the Quadro drive multiple displays directly.

Sustained professional graphics load

The Quadro RTX 4000 is designed for continuous rendering, simulation and compute tasks rather than short gaming bursts. Its 8 GB GDDR6 frame buffer and 256-bit memory interface maintain stable throughput during extended workloads. The 90-percent-efficient power supply helps keep system thermals steady when the CPU and GPU run at high utilisation for long periods. ECC memory is not supported, so buyers who need error-correcting RAM should consider a different platform.
