AMD said on 24 September that Perplexity’s Portable Computer now runs on supported Windows machines built on its Ryzen AI Max Series processors, including the Ryzen AI Halo developer platform. The announcement extends a feature that had already reached Windows PCs on other vendors’ silicon.
The point of interest is billing rather than silicon. Perplexity subscribers running the tool on these machines can execute local AI tasks and recurring workflows on their own hardware without spending Perplexity Computer credits on inference. For an agent doing repeated work on a schedule, metered per-token cloud billing is where the cost accumulates.
AMD’s technical case rests on memory. Ryzen AI Max parts pair CPU and GPU with a large pool of shared memory, which is what allows a usefully sized model to stay resident alongside everyday applications instead of being swapped in and out. The company dates its first AI PC with a dedicated NPU in an x86 processor to 2023, and its first agentic PCs able to run agents locally to 2025.
What the announcement leaves out is as notable as what it says. AMD names no models, publishes no performance figures, lists no supported systems and does not define what counts as a supported Windows PC. Until that detail arrives, this is a subscriber feature on unspecified hardware.
