Can the Instinct MI455X run CARP?
Yes — here's how fast and up to what context, with real measured numbers.
CARP on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6022k | 9601.9-11735.6 t/s | ~19.6-24 (slow) |
| Q8 | yes | 6032k | 19203.7-23471.2 t/s | ~39.2-47.9 (slow) |
| Q4 | yes | 6036k | 34292.4-41912.9 t/s | ~70-85.5 (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 Instinct MI455X run CARP?▶
Yes. At Q4 it generates ~34292.4-41912.9 tok/s and fits up to 6036k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~70-85.5 tok/s.
How much context fits?▶
At Q4, up to about 6036k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
