HP Unveils ZBook Ultra G3a 16 Mobile Workstation Capable of Running 300B LLMs
HP announced the ZBook Ultra G3a 16 mobile workstation powered by AMD's Ryzen AI Max PRO 400 "Gorgon Halo" processors. The system supports up to 192GB of unified memory, allowing up to 160GB to be allocated as VRAM to run 300-billion-parameter LLMs locally. This represents a major hardware milestone by bringing massive large language model execution directly onto a portable laptop. It enables developers and enterprise professionals to run complex local AI workflows and handle sensitive data offline without relying on expensive cloud servers. Weighing 1.9 kg with a 17.9mm thickness, the workstation supports 100W performance output, optional 5G cellular connectivity, and easily replaceable components like the keyboard. It comes pre-installed with the Perplexity Computer local AI agent and professional design suite support, with launch scheduled for October 2026 at an estimated price of $7,449.
## BACKGROUND
Unified memory architecture allows the CPU and GPU to share a single high-speed memory pool, bypassing the VRAM limitations typically found on standard mobile discrete graphics cards. Executing large language models locally requires substantial memory capacity to store model weights, enabling faster inference and enhanced data privacy.
