HP’s ZBook Ultra G3a 16 is a mobile workstation that can run AI models of up to 300 billion parameters locally, with up to 192GB of unified memory and 160GB available for graphics memory. It is built around AMD’s Ryzen AI Max+ PRO 495, with a 55 TOPS NPU and a thermal design rated for up to 100W. The 16-inch workstation starts at 4.2lb and is 17.9mm thick. HP says it can run local large language models, multiple agents and professional applications at the same time, supports Autodesk Revit 2027, Autodesk 3ds Max and Chaos Enscape, offers a 5G option, and has an IT-replaceable keyboard. Perplexity Computer comes preloaded, with support for Autodesk Revit through the Windows MCP Connector; HP describes a hybrid setup in which users can call cloud models when a task needs them. The headline memory figures apply to configurable versions rather than every model. HP says the ZBook Ultra G3a 16 is expected to be available in October 2026, and has not announced pricing for the UAE or other markets.
