Can the Instinct MI440X run Viking?
Yes — here's how fast and up to what context, with real measured numbers.
Viking on the Instinct MI440X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1259k | 187.1-228.7 t/s | ~0.4-0.5 (slow) |
| Q8 | yes | 1385k | 374.2-457.3 t/s | ~0.8-0.9 (slow) |
| Q4 | yes | 1440k | 668.2-816.7 t/s | ~1.4-1.7 (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
