Overview

The HP Z6 G4 is a professional-grade tower workstation built around two Intel Xeon Gold 6148 processors, providing a combined 40 cores and 80 threads of processing power. Originally designed for enterprise environments demanding maximum computational throughput, this renewed unit brings that capability to creative professionals, engineers, and data scientists at a more accessible price point. The 1TB NVMe drive ensures the operating system and active projects load quickly, while the AMD Radeon Pro WX 4100 graphics card handles professional visualization tasks and multi-display configurations.

While the included 16GB of RAM is a starting point that will suit lighter tasks, users tackling large renders, complex simulations, or sizable datasets will want to take advantage of the Z6 G4's generous expansion capacity. The HP Z-series chassis is well-regarded for its internal layout, tool-free access, and robust cooling system capable of managing the thermal output of dual processors under sustained loads. With Windows 11 pre-installed, the workstation is ready to run current professional software out of the box.

Frequently Asked Questions

The Z6 G4 with dual Xeon Gold 6148 processors excels at multi-threaded tasks like 3D rendering, video encoding, large dataset analysis, and CAD work where 40 total cores can be fully utilized.
Yes, the HP Z6 G4 supports significant memory expansion. The dual-processor configuration provides multiple DIMM slots, allowing you to upgrade well beyond the included 16GB as your workload demands grow.
The AMD Radeon Pro WX 4100 is a professional-grade GPU with 4GB of GDDR5 memory, designed for CAD, 3D modeling, and multi-monitor setups. It supports up to four 4K displays via its four Mini DisplayPort outputs.
This is a renewed (refurbished) workstation. It has been inspected, tested, and restored to working condition, and it ships with Windows 11 installed.
As a full-tower workstation cooling dual Xeon processors, the Z6 G4 produces noticeable fan noise under heavy multi-core loads. It is designed for professional environments rather than quiet home office use.
