Can the Instinct MI455X run ESM1b?
Yes — here's how fast and up to what context, with real measured numbers.
ESM1b on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6022k | 9463.5-11566.5 t/s | ~19.3-23.6 (slow) |
| Q8 | yes | 6032k | 18927-23133 t/s | ~38.6-47.2 (slow) |
| Q4 | yes | 6036k | 33798.3-41309 t/s | ~69-84.3 (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.
