HP Z8 G4 dual Xeon workstation

The HP Z8 G4 is a tower workstation equipped with two Intel Xeon Gold 6136 processors, each running at 3.00GHz with 18 cores for a total of 24 cores. It ships with 128GB of DDR4 memory and a 1TB SATA SSD, plus an NVIDIA Quadro P5000 graphics card. Windows 11 Pro comes pre-installed for immediate professional use.

Ideal for CAD, rendering and data-heavy tasks

This system suits engineers, designers and analysts who need high core counts and certified professional graphics for multi-display workflows. The four 3.5-inch expansion bays allow additional local storage. Buyers who need more than 128GB of memory or a newer GPU architecture should consider other options.

1536GB maximum DDR4 capacity

The motherboard supports up to 1536GB of DDR4 memory across its slots, so the installed 128GB can be expanded significantly for larger datasets or simulation workloads. This ceiling is the key figure when planning memory upgrades for this platform.

Questions about this item

What does the 24-core figure mean for real workloads on this Z8 G4?

Two Xeon Gold 6136 processors each bring 18 cores at 3.00GHz, giving 24 total cores for parallel tasks such as rendering, simulation and large dataset analysis.

How does the SATA interface limit the 1TB SSD in daily use?

The 1TB SSD uses SATA, so its maximum throughput is bounded by the SATA link rather than faster storage protocols.

What physical space is needed to add more drives to the 3.5-inch bays?

The chassis provides four 3.5-inch bays, so additional 3.5-inch drives can be installed directly without adapters.
