Can the Instinct MI430X run Nemotron-H 56B?
Yes — here's how fast and up to what context, with real measured numbers.
Nemotron-H 56B on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 867k | 131.1-160.2 t/s | ~0.2-0.3 (slow) |
| Q8 | yes | 1037k | 262.1-320.4 t/s | ~0.5-0.6 (slow) |
| Q4 | yes | 1113k | 468.1-572.1 t/s | ~0.8-1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.
