AMD Ryzen AI MAX 395+: A Guide to ROCm, PyTorch

With the release of the AMD Ryzen AI MAX 395+, the landscape for local AI inference is shifting. AMD’s latest architecture brings adequate compute power to the desktop/mobile space, making it a prime candidate for running Large Language Models (LLMs) locally.

However, getting the software stack right can be tricky. If you want to harness the full power of the 395+ using ROCm, PyTorch, and llama.cpp, you need to follow a specific configuration path to avoid common compatibility errors.

Critical Prerequisites

Before you run a single command, you must ensure your environment meets these two strict requirements. Skipping these will result in installation failures or “Module Not Found” exceptions.

1. Python Version (Strict Requirement)

You must use Python 3.12.
Currently, the ROCm-supported builds of PyTorch do not support Python 3.13 or newer. Using a newer version will cause installation exceptions. We recommend using a virtual environment (venv) or Conda to keep your system clean.

2. AMD Drivers

You must have the latest drivers installed. Specifically, you need version 26.2.2 or later.

Step 1: Prepare the Environment

First, ensure you are in a terminal (PowerShell or Command Prompt) and have your Python 3.12 environment active.

Install ROCm Dependencies

To begin the installation of the ROCm stack, run the following command:

pip install --no-cache-dir ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/rocm_sdk_core-7.2.1-py3-none-win_amd64.whl ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/rocm_sdk_devel-7.2.1-py3-none-win_amd64.whl ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/rocm_sdk_libraries_custom-7.2.1-py3-none-win_amd64.whl ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/rocm-7.2.1.tar.gz

Step 2: Installing PyTorch with ROCm Support

Once the base ROCm dependencies are settled, you need to install the specific build of PyTorch that communicates with AMD GPUs.

pip install --no-cache-dir ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/torch-2.9.1%2Brocm7.2.1-cp312-cp312-win_amd64.whl ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/torchaudio-2.9.1%2Brocm7.2.1-cp312-cp312-win_amd64.whl ^
    https://repo.radeon.com/rocm/windows/rocm-rel-7.2.1/torchvision-0.24.1%2Brocm7.2.1-cp312-cp312-win_amd64.whl
