Refact-1.6B on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 5993k | 4587.2-5606.6 t/s | ~7.9-9.6 (slow) |
| Q8 | yes | 6017k | 9174.4-11213.1 t/s | ~15.8-19.3 (slow) |
| Q4 | yes | 6028k | 16382.8-20023.4 t/s | ~28.1-34.4 (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.
