Can the NVIDIA GeForce RTX 5090 run Stable LM 2 12B?

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

Stable LM 2 12B on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 22k 53.9-64.2 t/s ~1.2-1.4 (slow)
Q8 yes 96k 107.7-128.4 t/s ~2.4-2.9 (slow)
Q4 yes 129k 192.4-229.3 t/s ~4.3-5.1 (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 5090 run Stable LM 2 12B?โ–ถ

Yes. At Q4 it generates ~192.4-229.3 tok/s and fits up to 129k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~4.3-5.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 129k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
