AMD Unveils Ryzen AI Max PRO 400 Chips, Claims 300 Billion-Parameter Models Run Locally

AMD said its new Ryzen AI Max PRO 400 Series will power commercial AI PCs and workstations that can run up to 300 billion-parameter models locally, with systems from HP and Lenovo due in Q3 2026.
The launch pairs those chips with Ryzen AI Halo, AMD’s first compact local AI developer platform, whose June 2026 pre-orders target developers building agentic AI applications without relying on cloud compute.
Ryzen AI Halo starts with a Ryzen AI Max+ 395 and up to 128GB of unified memory for 200 billion-parameter models, while the next Halo version will move to PRO 400 chips with up to 192GB memory and 160GB VRAM.
AMD said the platform supports Windows and Linux and is optimized for ROCm, PyTorch, vLLM, llama.cpp, Ollama and other tools to let developers prototype, fine-tune and deploy on one machine.
The push reflects AMD’s bet that AI workloads are shifting from cloud servers to PCs that can execute real-time tasks locally, cut latency and keep sensitive data on device.
Can AMD’s cheaper AI hardware finally break NVIDIA’s powerful CUDA software monopoly?
AMD boasts more memory than Apple's Mac Studio. Is this the secret weapon for running giant AI models on your desk?
