HP Intel Xeon Z6 G4 Workstation 2X Gold 5122 (Renewed)

The HP Z6 G4 is a dual-socket workstation built on Intel's Scalable Platform, and this configuration pairs two Xeon Gold 5122 CPUs — each a 4-core, 8-thread part clocked at 3.6GHz base — with 192GB of registered ECC DDR4. What those numbers mean in practice: you have 8 physical cores and 16 threads available to the OS, with memory bandwidth distributed across both sockets' 6-channel memory controllers. The ECC designation is not marketing — it means the memory subsystem actively detects and corrects single-bit errors, which matters when you're running 8-hour simulation jobs where a silent data corruption event would invalidate results. The AMD WX 4100 provides four display outputs and ISV certification for CAD and visualization software, and the 250GB NVMe SSD handles OS and application duties at PCIe speeds.

This machine is built for professionals whose software licenses cost more than the hardware — engineers running ANSYS or NASTRAN, architects using Revit with large assembly files, or analysts working with datasets too large to comfortably fit in 64GB. It is not the right choice for real-time GPU rendering at scale or any workload where single-threaded IPC is the primary constraint, as the Skylake-SP architecture cedes ground to newer platforms there. As a renewed unit, it occupies a cost-effective position for studios or institutions standing up secondary workstations or expanding existing HP Z-series environments where platform familiarity and spare-parts availability are practical advantages.
