Can the NVIDIA GeForce RTX 3090 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 3090

QuantFits?Max contextSpeedBeyond context
FP16 yes 72k 61-72.7 t/s ~2.6-3.1 (slow)
Q8 yes 114k 122-145.4 t/s ~5.2-6.2 (slow)
Q4 yes 133k 217.9-259.7 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 3090 run Phi-4-Multimodal?โ–ถ

Yes. At Q4 it generates ~217.9-259.7 tok/s and fits up to 133k 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 133k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
