Qwen 2.5 14B needs 8.5 GB VRAM at Q4. The RTX 3060 12GB has 12 GB.
● Qwen 2.5 14B (Alibaba) is a 14B parameter model used for Code, math, multilingual reasoning. Excellent for technical tasks, strong at code generation.
VRAM Requirements
| Quantization | VRAM Needed | RTX 3060 12GB |
|---|---|---|
| Q4_K_M (recommended) | 8.5 GB | ✅ |
| Q8_0 (high quality) | 14.5 GB | ❌ |
Expected Performance
Running Qwen 2.5 14B at Q4 on the RTX 3060 12GB, expect approximately ~25 tokens/sec with Ollama or llama.cpp. That’s fast enough for interactive chat — you’ll see responses streaming in real-time.
Headroom: With 8.5 GB used out of 12 GB, you have 3.5 GB free for KV cache (context window). At 4K context, this is plenty. At 32K+ context you may need to reduce batch size.
About the RTX 3060 12GB

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.
