Can Ryzen AI Max+ 395 mini PC / Framework Desktop · 128 GB run Phi-4 (14B)?

128 GB unified · 256 GB/s memory bandwidth · Phi-4 (14B) has 14.7B parameters.

Short answer

Yes, excellent for chat; borderline for 64K-token documents.

Best quantization for chat: Q5_K_M (9.8 GB of weights) on Lemonade. Generation: 18–25 tok/s, leaving about 104 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Get it running

Copy-paste commands for the Q6_K build with a 16K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/phi-4-GGUF:Q6_K

Downloads 12.03 GB (Q6_K). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=16384 before `ollama serve` for long prompts.
