HP Z4 G4 Tower Workstation

The HP Z4 G4 is a new tower workstation built around a single Intel Xeon W-2135 six-core processor running at 3.7GHz. It ships with 16GB of DDR4 ECC memory, a 500GB NVMe SSD and a 2TB SATA drive, plus an NVIDIA Quadro P1000 graphics card with 4GB GDDR5. Windows 11 is pre-installed for immediate professional use.

Suits CAD, rendering and multi-display workflows

This configuration supports professional visual work such as CAD, content creation and rendering across up to four displays via Mini DisplayPort 1.4. The four-channel memory architecture and RAID 0/1/5/10 capability help with data-heavy projects. Buyers needing more than 16GB of installed memory or a higher-tier GPU for intensive simulation should consider other options.

16GB DDR4 ECC memory installed

The system arrives with 16GB of DDR4 ECC memory installed across its eight DIMM slots. This capacity determines how many large models or datasets can stay resident during multitasking. While the platform supports up to 512GB total, the shipped 16GB is the decisive figure for immediate workflow fit.
