HP Z4 G4 Workstation Xeon W-2235 3.8GHz 16GB DDR4 2TB NVMe Quadro P5000 16GB Windows 11 Pro

Single-Processor Xeon Workstation

This HP Z4 G4 mid-tower workstation is built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It targets engineers and designers who need certified single-thread performance for CAD, simulation and visualization workloads. The system ships with Windows 11 Pro and 16 GB of DDR4 2933 ECC registered memory in a 2 x 8 GB configuration. A 2 TB PCIe NVMe SSD provides the primary system drive.

Sustained Load Thermal Headroom

The 1000 W 80 Plus Gold power supply rated at 90 % efficiency delivers stable power to the CPU and Nvidia Quadro P5000 during extended render or compute jobs. ECC registered DDR4 memory corrects single-bit errors on the fly, preventing data corruption in long-running simulations. The mid-tower chassis uses toolless access to maintain airflow across the 256-bit GDDR5X graphics card and processor under continuous heavy load. This configuration supports up to 512 GB of DDR42933 memory for larger datasets.

PCIe Gen 3 NVMe and DisplayPort 1.4 Limits

The 2 TB M.2 SSD operates over a PCIe 3.0 x4 link, capping sequential throughput at the interface maximum rather than the drive peak. Quadro P5000 outputs drive up to four DisplayPort 1.4 monitors plus one dual-link DVI display, limiting HDR or 8K signalling to the bandwidth of that standard. The single-processor LGA 2066 platform provides a fixed number of PCIe lanes, so adding high-bandwidth storage or a second GPU reduces available connectivity for other expansion cards. Integrated Gigabit Ethernet and audio remain the only onboard I/O.
