QuantFits?Max contextSpeedBeyond context
FP16 yes 144k 4088-4872 t/s ~324.4-386.7 (slow)
Q8 yes 145k 8176-9744 t/s ~648.9-773.3 (slow)
Q4 yes 145k 14600-17400 t/s ~1158.7-1381 (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 4070 run MegaMolBART?โ–ถ

Yes. At Q4 it generates ~14600-17400 tok/s and fits up to 145k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1158.7-1381 tok/s.

How much context fits?โ–ถ

At Q4, up to about 145k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
