Can the Instinct MI440X run Falcon-40B?
Yes — here's how fast and up to what context, with real measured numbers.
Falcon-40B on the Instinct MI440X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 964k | 154.4-188.7 t/s | ~0.3-0.4 (slow) |
| Q8 | yes | 1086k | 308.7-377.3 t/s | ~0.6-0.8 (slow) |
| Q4 | yes | 1140k | 551.3-673.8 t/s | ~1.1-1.4 (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.
FAQ
Can the Instinct MI440X run Falcon-40B?▶
Yes. At Q4 it generates ~551.3-673.8 tok/s and fits up to 1140k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.1-1.4 tok/s.
How much context fits?▶
At Q4, up to about 1140k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
