QuantFits?Max contextSpeedBeyond context
FP16 yes 183k 402.1-479.2 t/s ~23.9-28.5 (slow)
Q8 yes 192k 804.2-958.4 t/s ~47.9-57 (slow)
Q4 yes 197k 1436.1-1711.5 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 Ti Super run mBART-50?โ–ถ

Yes. At Q4 it generates ~1436.1-1711.5 tok/s and fits up to 197k 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 197k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
