Can the NVIDIA GeForce RTX 5080 run Phi-4-Multimodal?

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

Phi-4-Multimodal on the NVIDIA GeForce RTX 5080

QuantFits?Max contextSpeedBeyond context
FP16 yes 15k 62.6-74.6 t/s ~2.6-3.1 (slow)
Q8 yes 58k 125.1-149.1 t/s ~5.2-6.2 (slow)
Q4 yes 77k 223.5-266.3 t/s ~9.3-11.1 (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 5080 run Phi-4-Multimodal?โ–ถ

Yes. At Q4 it generates ~223.5-266.3 tok/s and fits up to 77k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~9.3-11.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 77k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
