Why VRAM Matters for Llama 3 (8B)

Llama 3 8B is relatively efficient, but VRAM is still critical. An 8B parameter model at 4-bit precision (Q4_K_M) requires about 5-6GB of VRAM just for the model weights. The remaining VRAM is needed for the 'KV Cache' (context window). If you only have 8GB, you'll be limited to shorter conversations (approx. 4k-8k context). With 12GB or 16GB, you can utilize the full 8k context window and even run at higher precision (8-bit) for better accuracy.

Frequently Asked Questions

What are the minimum GPU requirements for Llama 3 8B?

The absolute minimum GPU requirement for Llama 3 8B is 6GB VRAM (for heavily quantized models), but 8GB VRAM is the practical minimum for a stable experience. For optimal performance with full context, 12GB VRAM is recommended.

Can I run Llama 3 8B on 6GB VRAM?

It is possible with heavy quantization (Q3_K_S) and very short context, but not recommended. You will likely face Out-Of-Memory (OOM) errors quickly. 8GB is the practical minimum.

Is RTX 3060 12GB good for Llama 3 8B?

Yes, the RTX 3060 12GB is arguably the best value card for this model. It has enough VRAM to run the model at Q6 or Q8 precision with full context, offering a great balance of price and performance.
