Can the NVIDIA GeForce RTX 5090 run Jiutian?

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

QuantFits?Max contextSpeedBeyond context
FP16 yes 854 47.1-56.1 t/s ~1.1-1.3 (slow)
Q8 yes 86k 94.1-112.2 t/s ~2.1-2.5 (slow)
Q4 yes 123k 168.1-200.3 t/s ~3.8-4.5 (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 Jiutian?โ–ถ

Yes. At Q4 it generates ~168.1-200.3 tok/s and fits up to 123k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.8-4.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 123k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
