Can the NVIDIA GeForce RTX 4090 run RMBG v2.0?

Yes โ€” here's how fast and up to what context, with real measured numbers.

RMBG v2.0 on the NVIDIA GeForce RTX 4090

QuantFits?Max contextSpeedBeyond context
FP16 yes 307k 1664.8-1984.1 t/s ~66.1-78.7 (slow)
Q8 yes 311k 3329.6-3968.1 t/s ~132.1-157.5 (slow)
Q4 yes 312k 5945.7-7086 t/s ~235.9-281.2 (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 4090 run RMBG v2.0?โ–ถ

Yes. At Q4 it generates ~5945.7-7086 tok/s and fits up to 312k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~235.9-281.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 312k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
