can it run

Can the RTX 3090 (24GB, used) run llama3.2 3B?

YES

Comfortably. 24GB of memory against a 4GB working set leaves headroom for context, the OS, and anything else you're running.

~220–360 tok/s

weights 2GB + KV cache 0.44GB at 4k context vs ~24GB usable → full. 2.4 GB needed of 24 GB usable — headroom for context

computed roofline: 936 GB/s × 0.46–0.76 efficiency window / 2.0GB (Q4_K_M) — bands, never points. Small models (under ~4.5B) run BELOW these bands — kernel-launch overhead keeps them from saturating bandwidth (measured against community medians, 09-06).

Community check: ~130 tok/s · 3-4B Q4 · 11 runs · just below our band (22% under the low edge) — localmaxxing.com
