Can the Instinct MI430X run phi-3-medium 14B?
Yes — here's how fast and up to what context, with real measured numbers.
phi-3-medium 14B on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2246k | 524.3-640.8 t/s | ~0.9-1.1 (slow) |
| Q8 | yes | 2331k | 1048.5-1281.5 t/s | ~1.8-2.2 (slow) |
| Q4 | yes | 2369k | 1872.3-2288.4 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.
FAQ
Can the Instinct MI430X run phi-3-medium 14B?▶
Yes. At Q4 it generates ~1872.3-2288.4 tok/s and fits up to 2369k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.2-3.9 tok/s.
How much context fits?▶
At Q4, up to about 2369k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
