Can the NVIDIA GeForce RTX 5090 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 NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 310k 172.1-205.1 t/s ~3.8-4.6 (slow)
Q8 yes 368k 344.3-410.3 t/s ~7.7-9.2 (slow)
Q4 yes 394k 614.7-732.6 t/s ~13.7-16.4 (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 NVIDIA GeForce RTX 5090 run phi-3-mini 3.8B?โ–ถ

Yes. At Q4 it generates ~614.7-732.6 tok/s and fits up to 394k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~13.7-16.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 394k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
