FP16 yes 306k 1334.5-1590.5 t/s ~57-68 (slow)
Q8 yes 310k 2669.1-3180.9 t/s ~114.1-135.9 (slow)
Q4 yes 312k 4766.2-5680.2 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 3090 run Pangu-Weather?โ–ถ

Yes. At Q4 it generates ~4766.2-5680.2 tok/s and fits up to 312k 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 312k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
