Qwen3-4B vs 0.6B: Speed vs Accuracy on 6GB GPU

By PulseAugur Editorial · [1 sources] ·

A comparison of the Qwen3-4B and Qwen3-0.6B models on a laptop with an RTX 3060 GPU revealed that the smaller 0.6B model is approximately three times faster but less accurate. The larger 4B model successfully answered all six document-based questions, while the 0.6B model failed two, one due to incorrect logic and another due to output format errors. The experiment, conducted using Ollama, highlighted a trade-off between speed and accuracy for local RAG applications. AI

    Qwen3 4B vs 0.6B on a 6 GB GPU: Speed, Memory, and Answer Quality

    <p>For my personal retrieval-augmented generation (RAG) study, I needed a local model to answer questions from documents. My laptop has an RTX 3060 Laptop GPU with 6 GiB of VRAM, so memory use mattered alongside speed.</p> <p>I compared <code>qwen3:4b</code> and <code>qwen3:0.6b<…
