Can the Instinct MI430X run Pythia-1.4b?
Yes — here's how fast and up to what context, with real measured numbers.
Pythia-1.4b on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 5999k | 5242.5-6407.5 t/s | ~9-11 (slow) |
| Q8 | yes | 6020k | 10485-12815 t/s | ~18-22 (slow) |
| Q4 | yes | 6030k | 18723.2-22883.9 t/s | ~32.1-39.3 (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
