Can the AMD Instinct MI455X run Hunyuan-Large?
Yes — here's how fast and up to what context, with real measured numbers.
Hunyuan-Large on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 13k | 31.7-38.8 t/s | ~0.1-0.1 (slow) |
| Q4 | yes | 340k | 56.7-69.3 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 Hunyuan-Large?▶
Yes. At Q4 it generates ~56.7-69.3 tok/s and fits up to 340k 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?▶
At Q4, up to about 340k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
