Can the Instinct MI430X run Stable Cascade?
Yes — here's how fast and up to what context, with real measured numbers.
Stable Cascade on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2943k | 1433.5-1752.1 t/s | ~2.5-3 (slow) |
| Q8 | yes | 2982k | 2867-3504.1 t/s | ~4.9-6 (slow) |
| Q4 | yes | 2999k | 5119.6-6257.3 t/s | ~8.8-10.7 (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.
FAQ
Can the Instinct MI430X run Stable Cascade?▶
Yes. At Q4 it generates ~5119.6-6257.3 tok/s and fits up to 2999k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~8.8-10.7 tok/s.
How much context fits?▶
At Q4, up to about 2999k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
