Overview

The HP Z6 G4 Workstation is a tower-class machine built for professionals who need substantial processing power without the cost of a brand-new system. At its core are two Intel Xeon Gold 6148 processors, each with 20 cores running at 2.4GHz, delivering a combined 40 cores and 80 threads. This level of parallel processing makes the Z6 G4 well-suited for tasks like 3D rendering, video encoding, simulation, and large-scale data analysis where software can take advantage of many threads simultaneously.

Storage duties are split between a 250GB NVMe SSD for the operating system and frequently used applications, and a 2TB hard drive for larger project files and archives. The AMD Radeon Pro WX 4100 graphics card provides certified driver support for professional applications such as SolidWorks, AutoCAD, and Adobe Creative Suite. While the included 16GB of RAM is a starting point, the Z6 G4 chassis supports extensive memory expansion, making it straightforward to scale up as workload demands grow. Running Windows 11, this renewed workstation delivers enterprise-grade reliability in a package that represents strong value for studios, engineering teams, and content creators.
