Can the AMD Ryzen AI Max+ 395 run OpenPhenom-S/16?
Yes — here's how fast and up to what context, with real measured numbers.
OpenPhenom-S/16 on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1729k | 452.9-553.6 t/s | ~17.7-21.6 (slow) |
| Q8 | yes | 1732k | 905.8-1107.1 t/s | ~35.4-43.2 (slow) |
| Q4 | yes | 1733k | 1617.6-1977 t/s | ~63.2-77.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
