HP Z4 G4 Mid-Tower Workstation Xeon W-2223 3.6GHz 32GB DDR4 1TB NVMe Quadro RTX 5000 16GB Windows 11 Pro

HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower workstation built for professional workloads. It runs an Intel Xeon W-2223 3.6GHz 4-core processor with 32GB DDR4 2666 ECC memory. A 1TB NVMe SSD provides fast system storage. An NVIDIA Quadro RTX 5000 16GB GDDR6 card handles certified 3D and GPU-accelerated applications. Windows 11 Pro is pre-installed.

Suited For Professional Visualisation

This system suits engineers, designers and analysts running ISV-certified CAD, rendering or simulation software that relies on Quadro drivers and ECC memory. The 1000W 80 Plus Gold supply supports the installed GPU and leaves headroom for additional PCIe cards. Buyers who need higher core counts for heavy CPU compute or multiple double-width GPUs should look at larger chassis platforms.

Quadro RTX 5000 16GB Graphics

The deciding specification is the NVIDIA Quadro RTX 5000 with 16GB GDDR6 VRAM on a 256-bit bus. It offers four DisplayPort 1.4 outputs plus VirtualLink for professional displays and VR devices. This GPU targets workflows requiring certified drivers, large frame buffers and hardware ray-tracing acceleration. If your applications do not need workstation-class graphics or 16GB VRAM, a lower-tier card reduces cost.
