No. Qwen3.8 27B does not fit on RTX 3080 10GB: Default needs 20.3 GB and 9.5 GB is usable.
Hardware: RTX 3080 10GB · Model: Qwen3.8 27B
RTX 3080 10GB has 10 GB of VRAM and 760 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 9.5 GB. Partial offload may also use 60% of that system RAM. Qwen3.8 27B (27B, Alibaba) at Default is a 18 GB download and needs 20.3 GB with headroom for about 8k tokens.

Smallest hardware that runs it: RTX 3060 12GB at Default (partial offload (slower), 20.3 GB needed, 11.5 GB usable, about 4 tok/s (estimate)). Can a RTX 3060 12GB run Qwen3.8 27B?
A smaller Alibaba model that fits this hardware: Qwen 2.5 14B at Q4_K_M (partial offload (slower), 10.3 GB). Can a RTX 3080 10GB run Qwen 2.5 14B?
