Can the AMD Instinct MI455X run MiniMax-M1-80k?
Yes โ here's how fast and up to what context, with real measured numbers.
MiniMax-M1-80k on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | โ | โ | โ |
| Q8 | no | โ | โ | โ |
| Q4 | yes | 268k | 48.4-59.1 t/s | ~0.1-0.1 (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.

Can the AMD Instinct MI455X run MiniMax-M1-80k?โถ
Yes. At Q4 it generates ~48.4-59.1 tok/s and fits up to 268k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.1-0.1 tok/s.
How much context fits?โถ
At Q4, up to about 268k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
