Can the Instinct MI455X run TinyLlama-1.1B (3T token checkpoint)?
Yes — here's how fast and up to what context, with real measured numbers.
TinyLlama-1.1B (3T token checkpoint) on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6008k | 5612.7-6860 t/s | ~11.5-14 (slow) |
| Q8 | yes | 6025k | 11225.5-13720 t/s | ~22.9-28 (slow) |
| Q4 | yes | 6032k | 20045.5-24500 t/s | ~40.9-50 (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 TinyLlama-1.1B (3T token checkpoint)?▶
Yes. At Q4 it generates ~20045.5-24500 tok/s and fits up to 6032k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~40.9-50 tok/s.
How much context fits?▶
At Q4, up to about 6032k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
