Can the AMD Instinct MI455X run Belle VL?
Yes — here's how fast and up to what context, with real measured numbers.
Belle VL on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2246k | 441-539 t/s | ~0.9-1.1 (slow) |
| Q8 | yes | 2331k | 882-1078 t/s | ~1.8-2.2 (slow) |
| Q4 | yes | 2369k | 1575-1925 t/s | ~3.2-3.9 (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.
