Can the Instinct MI455X run Qwen3-235B-A22B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen3-235B-A22B on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 307k | 52.5-64.2 t/s | ~0.1-0.1 (slow) |
| Q4 | yes | 504k | 93.8-114.7 t/s | ~0.2-0.2 (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.
