FP16 yes 194k 1049.4-1250.6 t/s ~57-68 (slow)
Q8 yes 198k 2098.8-2501.3 t/s ~114.1-135.9 (slow)
Q4 yes 200k 3747.8-4466.5 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 4080 run Pangu-Weather?โ–ถ

Yes. At Q4 it generates ~3747.8-4466.5 tok/s and fits up to 200k 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 200k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
