Can a RTX 3080 12GB run Qwen 2.5 32B?

No. Qwen 2.5 32B does not fit on RTX 3080 12GB: Q4_K_M needs 22.2 GB and 11.5 GB is usable.

Hardware: RTX 3080 12GB · Model: Qwen 2.5 32B

RTX 3080 12GB has 12 GB of VRAM and 912 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 11.5 GB. Partial offload may also use 60% of that system RAM. Qwen 2.5 32B (32.8B, Alibaba) at Q4_K_M is a 20 GB download and needs 22.2 GB with headroom for about 8k tokens.
