HP Z4 G4 Workstation Xeon W-2135 3.7GHz 32GB 250GB NVMe 2TB Quadro P1000

Professional CAD workstation

The HP Z4 G4 tower workstation is built for engineers, designers and content creators who need reliable performance for CAD, rendering and data-heavy applications. A single Intel Xeon W-2135 six-core processor running at 3.7GHz with 12 threads handles multi-threaded workloads. The system ships with 32GB of DDR4 ECC memory across four channels and a 250GB NVMe drive alongside a 2TB SATA drive. Windows 11 is preinstalled for immediate setup.

Thermals and power in daily use

The 750W power supply delivers energy to the Xeon CPU and NVIDIA Quadro P1000 graphics card with 4GB GDDR5 memory. Internal 3.5-inch bays include acoustic dampening rail assemblies to reduce vibration noise during typical office hours. Two LAN ports provide wired network connectivity without adding wireless hardware. The Quadro P1000 drives up to four displays through Mini DisplayPort 1.4 outputs for multi-monitor professional setups.

Sustained load behaviour

Four-channel DDR4 architecture at 2666MHz maintains memory bandwidth during extended rendering or simulation tasks. Onboard SATA controller with RAID 0/1/5/10 support keeps storage arrays stable under continuous read and write cycles. Eight DIMM slots allow memory expansion up to 512GB when larger datasets exceed the installed 32GB capacity. Two PCI Express x16 Gen 3 slots support additional graphics cards for compute-intensive workloads beyond the Quadro P1000 capability.
