Dual Xeon Gold 6148 Workstation

The HP Z8 G4 workstation ships with two Intel Xeon Gold 6148 processors, each running at 2.40GHz with 24 cores, providing 48 threads for parallel workloads. It is configured with 256GB of DDR4 memory and a 1TB NVMe drive, with Windows 11 Pro preinstalled. The chassis includes four 3.5" expansion bays and weighs 55 units.

Suited for CAD and rendering.

This system targets engineers, designers and content creators who rely on CPU-heavy tasks such as CAD, rendering and data analysis. The NVIDIA Quadro K620 drives professional visual applications and multi-display setups. Buyers who need high-end GPU compute performance or multiple double-slot graphics cards should consider a different platform.

Memory ceiling: 1536GB DDR4

The platform supports a maximum of 1536GB of DDR4 memory across its slots, with 256GB installed at purchase. This ceiling determines whether the workstation can accommodate future dataset growth or must be replaced sooner. Verify your projected memory footprint against this limit before committing.
