Can the Instinct MI430X run GPT-2 (774M)?
Yes — here's how fast and up to what context, with real measured numbers.
GPT-2 (774M) on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6018k | 9482.6-11589.8 t/s | ~16.3-19.9 (slow) |
| Q8 | yes | 6030k | 18965.1-23179.6 t/s | ~32.6-39.8 (slow) |
| Q4 | yes | 6035k | 33866.3-41392.1 t/s | ~58.1-71.1 (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.
FAQ
Can the Instinct MI430X run GPT-2 (774M)?▶
Yes. At Q4 it generates ~33866.3-41392.1 tok/s and fits up to 6035k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~58.1-71.1 tok/s.
How much context fits?▶
At Q4, up to about 6035k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
