## Definition

Ryzen AI Max PRO 400 Series is AMD's commercial line of Zen 5 processors built for workstation-class "Agent Computers" that run large AI models on the device instead of the cloud. Three SKUs share a 192GB unified-memory ceiling, up 50% from the prior generation's 128GB cap.

AMD unveiled the lineup on [May 20, 2026](https://www.amd.com/en/blogs/2026/amd-powers-next-generation-agent-computers-with-new-ryzen-ai-hal.html), calling the flagship Max+ PRO 495 the first x86 chip able to run 300-billion-parameter models locally at 4-bit quantization. HP and Lenovo committed as launch OEM partners, with systems shipping Q3 2026 under AMD SVP Jack Huynh.

## Example

GMKtec confirmed its EVO-X3 mini-PC will ship with the Ryzen AI Max+ PRO 495 and 192GB of memory later in 2026, one of the first named third-party systems built around the chip outside HP and Lenovo's OEM channel.

## Analogy

It's a small workstation that keeps a 300-billion-parameter brain in-house instead of renting one from the cloud.

## Why it's emerging now

AMD confirmed the Ryzen AI Max PRO 400 Series on May 20, 2026 as the engine for its new "Agent Computers" category, with HP and Lenovo shipping systems in Q3 2026 to compete against Nvidia's DGX Spark and Apple's Mac Studio for the on-device LLM workstation market.
