QuantFits?Max contextSpeedBeyond context
FP16 yes 182k 537.1-640.1 t/s ~22.4-26.7 (slow)
Q8 yes 192k 1074.2-1280.2 t/s ~44.8-53.3 (slow)
Q4 yes 196k 1918.2-2286.1 t/s ~79.9-95.3 (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 5080 run ESM1b?โ–ถ

Yes. At Q4 it generates ~1918.2-2286.1 tok/s and fits up to 196k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~79.9-95.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 196k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
