Can the Instinct MI455X run VILA1.5-13B?
Yes — here's how fast and up to what context, with real measured numbers.
VILA1.5-13B on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2252k | 457.5-559.2 t/s | ~0.9-1.1 (slow) |
| Q8 | yes | 2334k | 915.1-1118.4 t/s | ~1.9-2.3 (slow) |
| Q4 | yes | 2371k | 1634.1-1997.2 t/s | ~3.3-4.1 (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.
