Can the NVIDIA GeForce RTX 5090 run OPT-1.3B (finetuned on PTB)?

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

OPT-1.3B (finetuned on PTB) on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 387k 503.1-599.6 t/s ~11.2-13.4 (slow)
Q8 yes 406k 1006.3-1199.3 t/s ~22.5-26.8 (slow)
Q4 yes 415k 1796.9-2141.5 t/s ~40.1-47.8 (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 5090 run OPT-1.3B (finetuned on PTB)?โ–ถ

Yes. At Q4 it generates ~1796.9-2141.5 tok/s and fits up to 415k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~40.1-47.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 415k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
