Professional workstation for design and engineering

The HP Z4 G4 tower is built for professional work such as design, content creation, rendering, engineering, and data-heavy applications. It uses an Intel Xeon W-2135 processor running at 3.70 GHz with six cores. The system includes 32GB of DDR4 memory across eight slots and a 512GB SATA SSD. An NVIDIA Quadro K620 with 2GB video memory handles professional visual tasks. No operating system is installed.

Sustained performance with Xeon stability

The Intel Xeon W-2135 processor provides responsive performance for design, rendering, engineering, and other demanding professional tasks during extended sessions. 32GB DDR4 memory supports smooth multitasking and helps handle larger professional projects and files without slowdown. The 512GB SATA SSD provides quick access to applications and project files with capacity for everyday professional work. The Quadro K620 supports professional visual work such as CAD, content creation, rendering, and multi-display setups.

Straightforward tower installation

The tower form factor allows standard component access for memory upgrades across eight DDR4 slots and storage expansion via SATA III interfaces. The single processor configuration simplifies thermal management compared to dual-socket systems. Buyers who need an operating system pre-installed must add one separately. The workstation targets professional visual workflows rather than high-end compute clusters or gaming-focused builds.

Questions about this item

How loud and hot does the Xeon W-2135 get when rendering all day?

The 6-core Xeon W-2135 runs at 3.70 GHz and the Z4 G4 tower chassis is engineered for professional thermal management during sustained CAD and rendering workloads.

What display cables must I already own for the Quadro K620?

The Quadro K620 with 2GB video memory drives professional displays through its native output ports, so have the matching DisplayPort or DVI cables ready for your monitors.

Will my existing DDR4 ECC modules work in the 8 memory slots?

The system ships with 32GB DDR4 installed across 8 slots, so any additional DDR4 ECC RDIMMs you add must match that specification for compatibility.
