Can the NVIDIA GeForce RTX 3090 Ti run Phi-2?

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

Phi-2 on the NVIDIA GeForce RTX 3090 Ti

QuantFits?Max contextSpeedBeyond context
FP16 yes 232k 136.3-162.4 t/s ~5.4-6.4 (slow)
Q8 yes 273k 272.5-324.8 t/s ~10.8-12.9 (slow)
Q4 yes 291k 486.7-580 t/s ~19.3-23 (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 Ti run Phi-2?โ–ถ

Yes. At Q4 it generates ~486.7-580 tok/s and fits up to 291k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~19.3-23 tok/s.

How much context fits?โ–ถ

At Q4, up to about 291k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
