Can the NVIDIA GeForce RTX 5080 run Qwen2-0.5B?

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

Qwen2-0.5B on the NVIDIA GeForce RTX 5080

QuantFits?Max contextSpeedBeyond context
FP16 yes 186k 700.8-835.2 t/s ~29.2-34.8 (slow)
Q8 yes 194k 1401.6-1670.4 t/s ~58.4-69.6 (slow)
Q4 yes 197k 2502.9-2982.9 t/s ~104.3-124.3 (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 Qwen2-0.5B?โ–ถ

Yes. At Q4 it generates ~2502.9-2982.9 tok/s and fits up to 197k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~104.3-124.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 197k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
