Phi-4 14B needs 8.5 GB VRAM at Q4. The RTX 4060 8GB has 8 GB.
Φ Phi-4 14B (Microsoft) is a 14B-parameter model for reasoning, math, structured tasks. Microsoft’s reasoning-focused model, punches above its size. The question is whether the RTX 4060 8GB’s 8 GB of VRAM can hold it — here’s the exact math.
VRAM requirements
| Quantization | VRAM needed | RTX 4060 8GB |
|---|---|---|
| Q4_K_M (recommended) | 8.5 GB | ❌ |
| Q8_0 (near-lossless) | 15 GB | ❌ |
Why it won’t fit (and what to do)
Phi-4 14B needs 8.5 GB at Q4 but the RTX 4060 8GB has only 8 GB — you’re 0.5 GB short. You can offload layers to system RAM, but expect single-digit tokens/sec (painfully slow for chat).

Frequently asked questions
Can the RTX 4060 8GB run Phi-4 14B?
No — not enough VRAM without CPU offloading. Phi-4 14B needs 8.5 GB VRAM at Q4_K_M; the RTX 4060 8GB has 8 GB.
How much VRAM does Phi-4 14B need?
Phi-4 14B needs about 8.5 GB at Q4_K_M (recommended) and 15 GB at Q8_0.
How many tokens per second will the RTX 4060 8GB get on Phi-4 14B?
It won't fit in VRAM; with CPU offloading expect very slow single-digit tokens/sec.
About the speed figure. The tokens/sec number above is an estimate, not a measured benchmark. Real throughput depends on your runtime and backend (Ollama, llama.cpp, vLLM), the exact quantization you download, context length, memory bandwidth, and whether any layers are offloaded to CPU. Treat it as a rough guide to the tier of performance, not a promised result.
