QuantFits?Max contextSpeedBeyond context
FP16 yes 419k 2555-3045 t/s ~57-68 (slow)
Q8 yes 422k 5110-6090 t/s ~114.1-135.9 (slow)
Q4 yes 424k 9125-10875 t/s ~203.7-242.7 (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 Pangu-Weather?โ–ถ

Yes. At Q4 it generates ~9125-10875 tok/s and fits up to 424k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~203.7-242.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 424k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
