Z4 G4 Xeon W-2235 Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory, a 500 GB PCIe NVMe SSD and an Nvidia Quadro RTX 4000 graphics card with 8 GB GDDR6. Windows 11 Pro is pre-installed.

Suited For Professional Visualisation

This configuration serves engineers, architects and content creators who need ISV-certified stability for 3D CAD, rendering and GPU-accelerated workloads. The 1000 W 80 Plus Gold power supply and tool-less chassis support future storage and memory expansion up to 512 GB. Buyers who need multi-processor scaling or more than three DisplayPort 1.4 outputs should evaluate alternative platforms.

Quadro RTX 4000 8 GB GDDR6

The installed Nvidia Quadro RTX 4000 provides 8 GB of GDDR6 memory on a 256-bit bus and drives up to four displays via three DisplayPort 1.4 connectors and one USB-C port. This GPU specification determines suitability for professional visualisation pipelines and GPU compute tasks.

Questions about this item

What does the 4.6 GHz turbo frequency mean once the Xeon W-2235 is under load in this Z4 G4?

The processor can boost up to 4.6 GHz on active cores when thermal headroom allows, accelerating single-threaded tasks like CAD geometry rebuilds or simulation pre-processing.

What does the PCIe-based NVMe interface cap in practice for the 500 GB SSD?

The M.2 NVMe drive runs over PCIe lanes, delivering sequential throughput well above SATA limits for faster project loading and OS responsiveness.

What clearance and power connections does the Quadro RTX 4000 need to fit in this mid-tower?

The card occupies a full-height double-width PCIe slot, draws power from the 1000 W 80 Plus Gold supply via internal connectors, and fits the tool-less chassis rails.
