Can the Instinct MI440X run Qwen2.5-3B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-3B on the Instinct MI440X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 5947k | 1998.1-2442.1 t/s | ~4.1-5 (slow) |
| Q8 | yes | 5994k | 3996.1-4884.1 t/s | ~8.2-10 (slow) |
| Q4 | yes | 6015k | 7135.9-8721.7 t/s | ~14.6-17.8 (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.
