Perplexity's local agent moves beyond Nvidia to AMD's Ryzen AI Max PCs

Your move: Needs 24GB or more of GPU memory, same bar as the Nvidia version

On September 24, 2026, Perplexity brought Portable Computer, the version of its Computer agent that runs entirely on your own hardware instead of the cloud, to Windows PCs built on AMD's Ryzen AI Max series chips, including AMD's Ryzen AI Halo developer platform. It had launched in August 2026 for Nvidia's DGX Spark and RTX Linux machines, then expanded to Nvidia-powered Windows PCs in September. The AMD version needs at least 24GB of GPU-accessible memory and runs one of two local models, Qwen 3.8 27B or Perplexity's own PPLX 27B, along with the agent's scheduler and sandbox, entirely on the device. It's available now to Pro and Max subscribers through the Perplexity app for Windows.

Why it matters

This is another step in the same direction as the earlier Nvidia rollout: more people can run Perplexity's agent locally, with zero ongoing token cost, without needing Nvidia hardware specifically. If you have a compatible AMD Ryzen AI Max PC with enough GPU memory, you can now use Portable Computer instead of the cloud version. If you don't have qualifying hardware, there's nothing to do yet.
