// RUN โ€” FITS

Can the AMD Instinct MI325X run phi-3.5-mini?

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

phi-3.5-mini on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 3455k 497.4-607.9 t/s ~3.3-4.1 (slow)
Q8 yes 3513k 994.7-1215.8 t/s ~6.6-8.1 (slow)
Q4 yes 3538k 1776.3-2171.1 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 MI325X run phi-3.5-mini?โ–ถ

Yes. At Q4 it generates ~1776.3-2171.1 tok/s and fits up to 3538k 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 3538k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
