Can the NVIDIA GeForce RTX 5080 run Qwen3-1.7B?

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

Qwen3-1.7B on the NVIDIA GeForce RTX 5080

QuantFits?Max contextSpeedBeyond context
FP16 yes 150k 206.1-245.6 t/s ~8.6-10.2 (slow)
Q8 yes 176k 412.2-491.3 t/s ~17.2-20.5 (slow)
Q4 yes 187k 736.1-877.3 t/s ~30.7-36.6 (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 5080 run Qwen3-1.7B?โ–ถ

Yes. At Q4 it generates ~736.1-877.3 tok/s and fits up to 187k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~30.7-36.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 187k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
