Can the NVIDIA GeForce RTX 3090 run OPT-2.7B (finetuned on WT2)?

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

OPT-2.7B (finetuned on WT2) on the NVIDIA GeForce RTX 3090

QuantFits?Max contextSpeedBeyond context
FP16 yes 232k 126.5-150.8 t/s ~5.4-6.4 (slow)
Q8 yes 273k 253.1-301.6 t/s ~10.8-12.9 (slow)
Q4 yes 291k 451.9-538.6 t/s ~19.3-23 (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 OPT-2.7B (finetuned on WT2)?โ–ถ

Yes. At Q4 it generates ~451.9-538.6 tok/s and fits up to 291k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~19.3-23 tok/s.

How much context fits?โ–ถ

At Q4, up to about 291k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
