Can the AMD Instinct MI455X run Llama Nemotron Super 49B?
Yes — here's how fast and up to what context, with real measured numbers.
Llama Nemotron Super 49B on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 909k | 126-154 t/s | ~0.3-0.3 (slow) |
| Q8 | yes | 1059k | 252-308 t/s | ~0.5-0.6 (slow) |
| Q4 | yes | 1125k | 450-550 t/s | ~0.9-1.1 (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.
