Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-1.5B on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 5995k | 4765.9-5825 t/s | ~8.2-10 (slow) |
| Q8 | yes | 6018k | 9531.8-11650 t/s | ~16.4-20 (slow) |
| Q4 | yes | 6028k | 17021.1-20803.6 t/s | ~29.2-35.7 (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.
