Can I run Phi-4-reasoning on Nvidia GeForce RTX 2060 (6GB)?
No. Phi-4-reasoning needs ~10.1 GB even at Q4_K_M, but Nvidia GeForce RTX 2060 (6GB) only has ~5 GB usable.
Needs ~10.1 GB even at Q4_K_M, but only ~5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 5.1 GB: Phi-4-reasoning needs roughly 10.1 GB at Q4_K_M and Nvidia GeForce RTX 2060 (6GB) leaves only about 5 GB usable for a model. The lightest tracked hardware that runs Phi-4-reasoning is the Nvidia GeForce RTX 3060 (12GB) at 12 GB. See Phi-4-reasoning on Nvidia GeForce RTX 3060 (12GB).
Too big for Nvidia GeForce RTX 2060 (6GB)'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.

FAQ
Can Nvidia GeForce RTX 2060 (6GB) run Phi-4-reasoning?
No. Phi-4-reasoning needs ~10.1 GB even at Q4_K_M, but Nvidia GeForce RTX 2060 (6GB) only has ~5 GB usable.
How much memory does Phi-4-reasoning need?
Nvidia GeForce RTX 2060 (6GB) does not have enough memory. At Q4_K_M the weights are ~8.43 GB; with KV cache and runtime overhead, budget ~10.1 GB at a 4k context.
What is the best tool to run Phi-4-reasoning 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.
