Can the NVIDIA GeForce RTX 5090 run Kosmos-2?

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

Kosmos-2 on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 378k 408.8-487.2 t/s ~9.1-10.9 (slow)
Q8 yes 402k 817.6-974.4 t/s ~18.3-21.8 (slow)
Q4 yes 413k 1460-1740 t/s ~32.6-38.8 (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 Kosmos-2?โ–ถ

Yes. At Q4 it generates ~1460-1740 tok/s and fits up to 413k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~32.6-38.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 413k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
