HP announces the most powerful Windows AI PC ever built — Nvidia GB300 workstation can handle one trillion parameters thanks to its 784GB unified memory, but it won't be cheap

HP unveiled the ZGX Fury GB300 at Computex 2026, a powerful deskside AI supercomputer featuring Nvidia’s Grace Blackwell Ultra technology designed for enterprise-level trillion-parameter model inference and development.

Key Points

  • The HP ZGX Fury GB300 utilizes Nvidia’s GB300 Grace Blackwell Ultra Desktop Superchip to deliver up to 20 petaflops of FP4 compute.
  • The system supports up to 784GB of coherent memory, enabling local processing of trillion-parameter AI models without relying on cloud infrastructure.
  • HP plans to launch the workstation in Q4 2026, with pricing expected to reach into the six-figure range for high-end configurations.
  • The device is designed to integrate directly into Windows-based enterprise environments, catering to organizations scaling AI agents and workflows.
  • Other industry partners, including Dell, MSI, ASUS, and Supermicro, are also developing solutions based on Nvidia’s new DGX Station architecture.

Why it Matters

These high-performance workstations allow enterprises to localize sensitive data and fine-tune massive AI models on-site rather than relying on external cloud services. By bringing datacenter-grade compute power to a deskside form factor, companies can significantly accelerate their internal AI development and deployment workflows.
