Can the Instinct MI455X run Qwen2-Audio?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen2-Audio on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2896k | 752.9-920.2 t/s | ~1.5-1.9 (slow) |
| Q8 | yes | 2958k | 1505.9-1840.5 t/s | ~3.1-3.8 (slow) |
| Q4 | yes | 2986k | 2689-3286.6 t/s | ~5.5-6.7 (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.
