Can the AMD Instinct MI455X run Intern-S2-Preview?
Yes — here's how fast and up to what context, with real measured numbers.
Intern-S2-Preview on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1243k | 176.4-215.6 t/s | ~0.4-0.4 (slow) |
| Q8 | yes | 1377k | 352.8-431.2 t/s | ~0.7-0.9 (slow) |
| Q4 | yes | 1436k | 630-770 t/s | ~1.3-1.6 (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 Intern-S2-Preview?▶
