QuantFits?Max contextSpeedBeyond context
FP16 yes 127k 301.6-359.4 t/s ~23.9-28.5 (slow)
Q8 yes 136k 603.1-718.8 t/s ~47.9-57 (slow)
Q4 yes 140k 1077-1283.6 t/s ~85.5-101.9 (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 Super run mBART-50?โ–ถ

Yes. At Q4 it generates ~1077-1283.6 tok/s and fits up to 140k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~85.5-101.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 140k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
