Can the AMD Instinct MI455X run openPangu 2.0 Pro?
Yes — here's how fast and up to what context, with real measured numbers.
openPangu 2.0 Pro on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | no | — | — | — |
| Q4 | yes | 216k | 43.7-53.4 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.
FAQ
Can the AMD Instinct MI455X run openPangu 2.0 Pro?▶
