Can I run Qwen3.6 27B on an RTX 3060 12GB?
No: Qwen3.6 27B needs about 19.9 GB at Q4_K_M with 32K tokens of context, 7.92 GB more than the RTX 3060 12GB holds, so it takes 2 of them (24 GB) in one tensor-parallel group. The smallest setup here that holds Qwen3.6 27B at Q4_K_M with 32K is RTX 3090 (24 GB).

Tensor parallel with the combined bandwidth, as in vLLM; llama.cpp splits layers by default and runs at about one card's speed.
Other options
- The next smaller setting, Q3_K_M, takes 16.6 GB at 32K, 4.61 GB over the RTX 3060; it does not fit with 0.5 GB to spare even with 1K tokens.
- Renting two RTX 3060 12GB GPUs costs about $0.16 an hour (median on getdeploying.com, 2026-09-29): $1.6–2.3 per million tokens at 19–27 tokens/s.
- Smallest setup for Q4_K_M at 32K: RTX 3090 (24 GB).
