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

Refact-1.6B on the NVIDIA GeForce RTX 3090

QuantFits?Max contextSpeedBeyond context
FP16 yes 265k 213.5-254.5 t/s ~9.1-10.9 (slow)
Q8 yes 290k 427.1-509 t/s ~18.3-21.8 (slow)
Q4 yes 300k 762.6-908.8 t/s ~32.6-38.8 (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 3090 run Refact-1.6B?โ–ถ

Yes. At Q4 it generates ~762.6-908.8 tok/s and fits up to 300k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~32.6-38.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 300k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
