Can the Instinct MI440X run FoundationStereo?
Yes — here's how fast and up to what context, with real measured numbers.
FoundationStereo on the Instinct MI440X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6031k | 18413.4-22505.2 t/s | ~37.6-45.9 (slow) |
| Q8 | yes | 6036k | 36826.7-45010.4 t/s | ~75.2-91.9 (slow) |
| Q4 | yes | 6039k | 65762-80375.8 t/s | ~134.2-164 (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.
