Can the Instinct MI455X run ESM2-8M?
Yes — here's how fast and up to what context, with real measured numbers.
ESM2-8M on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6041k | 771750-943250 t/s | ~1575-1925 (slow) |
| Q8 | yes | 6041k | 1543500-1886500 t/s | ~3150-3850 (slow) |
| Q4 | yes | 6041k | 2756250-3368750 t/s | ~5625-6875 (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.
