Can I run Phi-4 14B on Nvidia GeForce RTX 3060 (12GB)?
Yes. Phi-4 14B runs on Nvidia GeForce RTX 3060 (12GB) at Q4_K_M (~10.8 GB of ~11 GB usable).
Fits at Q4_K_M (~10.8 GB of ~11 GB usable) but with little headroom. Close other apps; a smaller context frees a few hundred MB.
That figure is at a 4k context and moves about ±15% as context length changes. Nvidia GeForce RTX 3060 (12GB) leaves ~0.2 GB of headroom.

- ~1,430M tok
At ~$0.15/kWh and the estimated ~26 tok/s, a million generated tokens costs about $0.27 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$329 Nvidia GeForce RTX 3060 (12GB) pays for itself after roughly 1,430 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ
Can Nvidia GeForce RTX 3060 (12GB) run Phi-4 14B?
Yes. Phi-4 14B runs on Nvidia GeForce RTX 3060 (12GB) at Q4_K_M (~10.8 GB of ~11 GB usable).
How much memory does Phi-4 14B need?
It is a tight fit on Nvidia GeForce RTX 3060 (12GB). At Q4_K_M the weights are ~9.05 GB; with KV cache and runtime overhead, budget ~10.8 GB at a 4k context.
What is the best tool to run Phi-4 14B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
