Perplexity's local AI agent, Portable Computer, no longer needs an NVIDIA GPU to run. The company has extended support to PCs built on AMD's Ryzen AI Max series, including the Ryzen AI Halo developer platform, giving Windows users a second hardware path into the same local AI tools.
This matters because of how demanding Perplexity's NVIDIA version turned out to be. When Portable Computer launched on GeForce RTX hardware, it required a 24GB card just to run, a bar that shut out most mainstream gaming PCs and effectively limited the feature to workstation-class builds. The AMD version runs on Ryzen AI Max's unified memory architecture instead, which means the same local AI workflows can now reach laptops and mini PCs that were never going to ship with a 24GB discrete GPU in the first place.
Under the hood, Perplexity says Ryzen AI Max and Ryzen AI Halo systems can run models like Qwen 3.8 27B and its own PPLX 27B directly on device, letting users analyze sensitive files and run recurring workflows without burning cloud compute credits. The pitch bundles local models, agent orchestration, scheduling and security controls into one stack, plus integrations with Gmail, Outlook, Slack and GitHub, and enterprise controls like folder-level permissions and sandboxing.
The AMD version is live now through the Perplexity Windows app, limited to Pro and Max subscribers on individual and enterprise plans. That subscription gate has not changed between the NVIDIA and AMD versions, so the actual expansion here is which hardware qualifies, not who gets to use the feature.
For AMD, the deal is a chance to plant a flag in the AI PC conversation that NVIDIA and Qualcomm have mostly owned so far. For buyers, it is a genuinely useful signal. If you were priced out of Perplexity's local AI agent because you did not have a 24GB NVIDIA card, a Ryzen AI Max system is now a real alternative, not a downgrade.
