Can I run Qwen3.6 27B on Nvidia GeForce RTX 4060 Ti (16GB)?

Compatibility verdict VRAM threshold engine
No, not enough memory would not load

No. Qwen3.6 27B needs ~18.9 GB even at Q4_K_M, but Nvidia GeForce RTX 4060 Ti (16GB) only has ~15 GB usable.

Needs ~18.9 GB Device usable ~15 GB

Needs ~18.9 GB even at Q4_K_M, but only ~15 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 3.9 GB: Qwen3.6 27B needs roughly 18.9 GB at Q4_K_M and Nvidia GeForce RTX 4060 Ti (16GB) leaves only about 15 GB usable for a model. The lightest tracked hardware that runs Qwen3.6 27B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Qwen3.6 27B on Nvidia GeForce RTX 4090 (24GB).

Too big for Nvidia GeForce RTX 4060 Ti (16GB)'s VRAM, but you could offload some layers to system RAM and still run it at roughly ~7 tok/s, far slower than a model that fits. How this is estimated.
