Can RTX 3060 12GB run Qwen3.8 27B?

Partly: part of the model runs from system RAM (CPU offload, per the source). Measured 5.2-6.7 tok/s generation with part of the model offloaded to system RAM (llama.cpp, llama-bench tg128 (quant per result); source).

Memory: RTX 3060 12GB has 12 GB. Qwen3.8 27B weights are about 16.5 GB at Q4_K_M (27B params × 4.89 bits ÷ 8, before context/KV cache). Arithmetic, not a measurement; long contexts need more. Check other quants in the VRAM calculator.

Speeds are decode (generation) tokens/sec as reported by each source; quant, engine and context differ, so small gaps are noise.
