// RUN โ€” FITS

Can the AMD Radeon Pro W7900 48GB 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 Radeon Pro W7900 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 535k 71.6-87.5 t/s ~3.3-4.1 (slow)
Q8 yes 593k 143.2-175.1 t/s ~6.6-8.1 (slow)
Q4 yes 618k 255.8-312.6 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 Radeon Pro W7900 48GB run phi-3.5-mini?โ–ถ

Yes. At Q4 it generates ~255.8-312.6 tok/s and fits up to 618k 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 618k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
