Can the Instinct MI455X run Qwen-Audio-Chat?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen-Audio-Chat on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2892k | 729.8-892 t/s | ~1.5-1.8 (slow) |
| Q8 | yes | 2956k | 1459.6-1783.9 t/s | ~3-3.6 (slow) |
| Q4 | yes | 2985k | 2606.4-3185.6 t/s | ~5.3-6.5 (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.
