Professional CAD Workstation

The HP Z4 G4 is a new rackmount workstation built for professional design, engineering, rendering and data-heavy applications. An Intel Xeon W-2135 processor with 14 cores running at 3.70GHz provides responsive performance for demanding tasks. 16GB of DDR4 memory supports smooth multitasking across large project files.

Single-Processor LGA3647 Platform

This system supports a maximum of one processor in the LGA3647 socket, so CPU upgrades are limited to the installed W-2135. Memory can be expanded to 512GB of DDR4 across the available slots. Storage expansion uses two 3.5-inch bays and one M.2 slot for additional drives.

Entry-Level Quadro Visual Upgrade

The dedicated NVIDIA Quadro P4000 GPU replaces integrated graphics for certified CAD, content creation and multi-display workflows. Buyers who need higher GPU compute for complex simulation or deep-learning workloads will require a more powerful professional card. The 1TB NVMe drive handles everyday project storage; users with larger datasets should add secondary drives.

Questions about this item

Should I pick the 16GB DDR4 configuration or plan to expand toward the 512GB maximum?

The system ships with 16GB DDR4 installed and supports up to 512GB total; start with the factory memory and add modules later if your projects demand more capacity.

How does the Xeon W-2135 at 3.70GHz with 14 cores perform in a real CAD workload?

The 14-core Xeon W-2135 running at 3.70GHz delivers strong single-thread speed for interactive modelling and enough parallel threads for rendering and simulation tasks.

What does the M.2 slot and the 2x 3.5" bays allow for storage expansion?

The M.2 slot accepts an NVMe drive for fast boot and scratch space, while the two 3.5" bays provide room for additional high-capacity drives.
