HP Z4 G4 Business Desktop Xeon W-2235 128GB 4TB NVMe RTX 5000 16GB Windows 11 Pro

Professional workstation for compute workloads

The HP Z4 G4 mid-tower desktop is built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo across six cores. It ships with 128 GB of DDR4 2933 ECC registered memory in four 32 GB modules and a 4 TB PCIe NVMe solid-state drive. An Nvidia Quadro RTX 5000 graphics card with 16 GB of GDDR6 memory on a 256-bit bus provides four DisplayPort 1.4 outputs plus VirtualLink, all powered by a 1000 W 80 Plus Gold supply under Windows 11 Pro.

Suited for certified professional applications

This system targets engineers, designers and analysts who rely on ISV-certified drivers for 3D CAD, rendering, visualization and GPU-accelerated simulations. The Xeon platform supports up to 512 GB of DDR42933 ECC memory for large datasets, while the Quadro RTX 5000 delivers professional graphics stability. Buyers who need consumer gaming features or multiple graphics cards should look elsewhere because this workstation is validated for professional software stacks and single high-end GPU configurations.

16 GB GDDR6 Quadro RTX 5000 decides fit

The single specification that determines suitability is the Nvidia Quadro RTX 5000 with 16 GB of GDDR6 memory on a 256-bit interface driving four DisplayPort 1.4 connectors and VirtualLink. This GPU tier is certified for professional visualization and compute workloads that require validated drivers and error-correcting memory support. If your workflow demands a different VRAM capacity or consumer GeForce features, this specific graphics configuration will not match the requirement.
