Can the AMD Instinct MI300X 192GB run phi-3-mini 3.8B?

Yes โ€” here's how fast and up to what context, with real measured numbers.

phi-3-mini 3.8B on the AMD Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 2556k 439.3-537 t/s ~3.3-4.1 (slow)
Q8 yes 2614k 878.7-1073.9 t/s ~6.6-8.1 (slow)
Q4 yes 2640k 1569.1-1917.8 t/s ~11.8-14.5 (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 AMD Instinct MI300X 192GB run phi-3-mini 3.8B?โ–ถ

Yes. At Q4 it generates ~1569.1-1917.8 tok/s and fits up to 2640k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~11.8-14.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2640k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
