FAQ
How many local LLMs can the Ryzen AI Max+ 395 run?
42 of the 63 open-weight models in this directory fit, with 128 GB of unified memory, by this site's rule of thumb that the smallest non-MLX download is at most 85% of the memory. MLX builds do not count here: they run on Apple silicon only.
Can the Ryzen AI Max+ 395 run Mistral Medium 3.5 128B?
Yes, by this directory's rule of thumb: its smallest non-MLX download, 74.9 GB, is at most 85% of 128 GB (108.8 GB), the Q4_K_M GGUF build from unsloth/Mistral-Medium-3.5-128B-GGUF. That leaves room for the context and the operating system. It is a memory check, not a speed estimate.
Can the Ryzen AI Max+ 395 run NVIDIA Nemotron 3.5 Super VL 120B-A12B?
Yes, by this directory's rule of thumb: its smallest non-MLX download, 71.8 GB, is at most 85% of 128 GB (108.8 GB), the Q4_0 GGUF build from ggml-org/NVIDIA-Nemotron-3.5-Super-VL-120B-A12B-GGUF. That leaves room for the context and the operating system. It is a memory check, not a speed estimate.
Can the Ryzen AI Max+ 395 run Step 3.7 Flash?
Not by this directory's rule of thumb: its smallest non-MLX download, 111.5 GB, is more than 85% of 128 GB (108.8 GB). It needs the 256 GB tier or more: https://www.developersdigest.tech/local-models/fits/256.
Is the Ryzen AI Max+ 395's memory shared with the operating system?
Yes. AMD lists LPDDR5x unified (256-bit) memory shared by the CPU and GPU, so the operating system and your apps use the same pool as the model. The 15% headroom in this directory's rule is there for that and for the context.
What memory bandwidth does the Ryzen AI Max+ 395 have?
AMD's spec page does not state a bandwidth figure, so this page shows Not stated. The memory is LPDDR5x unified (256-bit).
