Can the AMD Ryzen AI Max+ 395 run Nemotron-H 56B?
Yes — here's how fast and up to what context, with real measured numbers.
Nemotron-H 56B on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 5k | 1.4-1.8 t/s | ~0.1-0.1 (slow) |
| Q8 | yes | 176k | 2.9-3.5 t/s | ~0.1-0.1 (slow) |
| Q4 | yes | 251k | 5.1-6.3 t/s | ~0.2-0.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
