HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory across four modules and a 4 TB PCIe NVMe solid-state drive. An NVIDIA Quadro RTX 4000 graphics card with 8 GB of GDDR6 memory drives professional visual workloads. Windows 11 Pro is pre-installed and activated.

Suited to certified professional applications

This workstation targets engineers, designers and analysts who rely on ISV-certified stability for 3D CAD, rendering and simulation tasks. The Xeon platform supports up to 512 GB of DDR42933 ECC memory for large datasets. Buyers who need a compact form factor or integrated graphics should consider alternative configurations. The mid-tower chassis requires adequate desk space for deployment.

8 GB GDDR6 Quadro RTX 4000 GPU

The installed NVIDIA Quadro RTX 4000 provides 8 GB of GDDR6 video memory on a 256-bit bus with three DisplayPort 1.4 outputs and one USB-C connector. This specification determines whether the system can handle your target model complexity, texture resolution and multi-display arrangement. Verify that your application’s GPU memory requirements fit within this 8 GB frame buffer before purchasing.

Questions about this item

Should I pick the 32 GB DDR4 2933 or add more memory later?

The system ships with 32 GB (4 × 8 GB) DDR4 2933 ECC registered and supports up to 512 GB total, so you can start now and expand when workloads grow.

What does the Xeon W-2235 3.8 GHz (4.6 GHz Turbo) 6-core mean for daily rendering?

Six cores at 3.8 GHz base with 4.6 GHz turbo give strong single-thread speed for interactive viewport work and enough threads for overnight batch renders.

Will the Quadro RTX 4000 8 GB GDDR6 256-bit run three DisplayPort 1.4 monitors plus USB-C?

Yes — the card provides three DP 1.4 outputs and one USB-C video port, all driven from the 8 GB GDDR6 frame buffer.
