Can the AMD Ryzen AI Max+ 395 run Phi-4-Multimodal?
Yes — here's how fast and up to what context, with real measured numbers.
Phi-4-Multimodal on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 782k | 14.4-17.6 t/s | ~0.6-0.7 (slow) |
| Q8 | yes | 825k | 28.8-35.2 t/s | ~1.1-1.4 (slow) |
| Q4 | yes | 844k | 51.4-62.9 t/s | ~2-2.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
