Professional Workstation for Compute-Intensive

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor running at 3.8GHz with a 4.6GHz turbo frequency. It ships with 128GB of DDR4 2933 ECC registered memory in a four-module configuration and a 2TB PCIe NVMe solid-state drive. Windows 11 Pro is pre-installed for immediate deployment in professional environments.

ECC Memory Capacity Defines Data Integrity

The system includes 128GB of DDR4 2933 ECC registered memory across four 32GB modules, with the platform supporting up to 512GB total. This error-correcting architecture protects against data corruption during large dataset processing and complex simulations. Workloads that do not require ECC validation or exceed the installed capacity will need a different memory configuration.

Sustained Performance

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable current to the six-core Xeon and NVIDIA Quadro P2000 5GB GDDR5 graphics under continuous load. The Quadro P2000 provides a 160-bit memory interface and four DisplayPort 1.4 outputs for multi-display visualisation. Tool-less chassis access allows thermal management and component service without interrupting long-running compute tasks.

Questions about this item

What does the 3.8 GHz base clock with 4.6 GHz turbo mean for actual workloads?

The Xeon W-2235 runs at 3.8 GHz on all six cores and can boost to 4.6 GHz when thermal headroom allows, giving strong single-thread speed for CAD and simulation tasks.

How does the PCIe NVMe interface affect the 2 TB drive's real-world throughput?

The 2 TB M.2 NVMe SSD connects over PCIe lanes, delivering sequential read and write speeds far above SATA limits for faster project loading and OS responsiveness.

What clearance and power does the Quadro P2000 need inside the mid-tower chassis?

The Quadro P2000 is a dual-slot card with four DisplayPort 1.4 outputs, powered from the 1000 W 80 Plus Gold supply and fits the Z4 G4's full-height PCIe slots.
