HP Z4 G4 Mid-Tower Workstation Intel Xeon W-2235 128GB DDR4 1TB NVMe Nvidia Quadro P5000 16GB Windows 11 Pro

Professional workstation for compute-intensive

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor with 6 cores running at 3.8 GHz and a 4.6 GHz turbo frequency. It ships with 128 GB of DDR4 2933 ECC registered memory in a 4x 32 GB configuration and a 1 TB PCIe NVMe solid state drive. An Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory and a 256-bit bus provides four DisplayPort 1.4 outputs and a dual-link DVI-D connector. Windows 11 Pro is pre-installed.

Thermals noise and power draw in normal use

A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency delivers power to the CPU, memory, storage and graphics card. The workstation chassis uses toolless access for internal components and includes multiple PCIe slots for expansion. Integrated Gigabit Ethernet and high-definition audio are provided on the motherboard. No monitor is included in the package.

Build integration needs and freedoms

The system supports up to 512 GB of DDR42933 ECC memory across available slots for larger datasets. Multiple internal storage bays and M.2 slots allow combinations of SATA and PCIe NVMe drives for additional capacity. Certified professional graphics support covers 3D CAD, rendering, visualization and GPU-accelerated workloads with ISV certification. The LGA 2066 socket and mid-tower form factor define the upgrade path for processors and add-in cards. Buyers who need a smaller footprint or integrated graphics should consider other form factors.
