The HP Z6 G4 is a high-performance workstation designed for professional “heavy-lifting” tasks like 3D rendering, video production, and scientific computing. Because this is a Renewed unit, it offers a high price-to-performance ratio for power users on a budget.

• Core Specifications & Performance

• Processor (Intel Xeon Gold 6138): This is a professional-grade server/workstation CPU with 20 cores and 40 threads.² While its base clock is lower ($2.0 text{ GHz}$), it is a “multi-threaded beast.” It excels in applications that can use many cores simultaneously, such as KeyShot, V-Ray, or Cinema 4D.
• Graphics (NVIDIA RTX 3060 12GB): While the Z6 is a workstation, the RTX 3060 is a “consumer” card. However, its 12GB of VRAM is a huge advantage for GPU rendering and video editing (like 4K/8K timelines in Premiere Pro or DaVinci Resolve) where memory capacity often matters more than raw speed.
•           Storage (2TB SSD): A generous amount of fast storage. The Z6 G4 chassis also has excellent room for expansion if you need to add more SATA or NVMe drives later.³
•       Operating System: Windows 11 Pro is the standard for modern professional environments, ensuring compatibility with the latest security updates and software versions.

• Task	Performance Level	Notes
  3D Rendering	Excellent	The 20-core Xeon handles CPU rendering beautifully.
  Video Editing	Very High	Smooth 4K editing; the 12GB VRAM handles heavy effects.
  AI / Machine Learning	Good	The 12GB VRAM is great for entry-level model training.
  CAD (AutoCAD/SolidWorks)	High	Very capable, though Xeon clock speeds are lower than i9s.
  Gaming	High	Will play most modern AAA games at 1440p easily.
