Yes. Qwen3.5 27B is a 17–20 GB download (Q4_K_M). The Ryzen AI Max+ 395 (64 GB) gives the GPU 48 GB, leaving about 28 GB for context and runtime (our arithmetic).
Does it fit?
| Qwen3.5 27B memory | 17–20 GB at Q4_K_M (Ollama: qwen3.5 tags) |
|---|---|
| Ryzen AI Max+ 395 (64 GB) GPU memory | 64 GB unified memory, of which AMD says up to 48 GB can be dedicated graphics memory through Variable Graphics Memory. We use 48 GB for fit. (AMD) |
| Left over | About 28 GB (our arithmetic) |
| Verdict | Fits 4 GB or more to spare (our estimate bands) |
Recommended quantization and context
Use the Q4_K_M build that Ollama's tag downloads; the memory figure above is for that build. The model supports up to 256K of context, but longer context uses more memory. Ollama starts at a 4096-token context by default (Ollama FAQ).
With about 28 GB spare you have room to raise the context. Raise it in steps and re-check with ollama ps.
On this mini PC the GPU's share of memory depends on settings. On Windows, set Variable Graphics Memory in AMD Software (Performance, then Tuning); on Linux, see AMD's ROCm notes on BIOS VRAM and GTT. Details are in the install guide.
Run it
ollama run qwen3.5:27bThen check it's on the GPU:
ollama psThe PROCESSOR column should read 100% GPU. Driver setup for AMD cards on Windows, Linux and macOS, plus common fixes, is in the install and run section.

Can the Ryzen AI Max+ 395 (64 GB) run Qwen3.5 27B?
Yes: Qwen3.5 27B needs 17–20 GB (Q4_K_M, Ollama library) and the Ryzen AI Max+ 395 (64 GB) gives the GPU 48 GB, leaving about 28 GB. That leaves room to raise the context above the 4096-token default. The fit bands are our estimate.
How much VRAM does Qwen3.5 27B need?
17–20 GB for the Q4_K_M build in the Ollama library, plus roughly 1–4 GB for context and runtime (our estimate). See the 24 GB page for other models that fit.
What command runs Qwen3.5 27B?
ollama run qwen3.5:27b. Then run "ollama ps" and check the PROCESSOR column reads 100% GPU.
How fast is Qwen3.5 27B on the Ryzen AI Max+ 395 (64 GB)?
We don't list a speed because we have no sourced measurement for this pairing. Speed depends on memory bandwidth, quantization and context length.
