Llama 3.1 8B needs 5 GB VRAM at Q4. The RTX 4060 8GB has 8 GB.
🦙 Llama 3.1 8B (Meta) is a 8B-parameter model for general chat, coding, instruction following. Strong all-rounder, comparable to GPT-3.5. 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) | 5 GB | ✅ |
| Q8_0 (near-lossless) | 8.5 GB | ❌ |
Expected performance
Running Llama 3.1 8B at Q4 on the RTX 4060 8GB, expect roughly ~36 tokens/sec in Ollama or llama.cpp — comfortably faster than reading speed, so chat feels responsive.
Headroom: 5 GB used of 8 GB leaves about 3 GB free for KV cache (context). That’s fine for 4-8K context; for 32K+ you may need a smaller batch or a lower quant.

Frequently asked questions
Can the RTX 4060 8GB run Llama 3.1 8B?
Yes — runs great at Q4 (recommended). Llama 3.1 8B needs 5 GB VRAM at Q4_K_M; the RTX 4060 8GB has 8 GB.
How much VRAM does Llama 3.1 8B need?
Llama 3.1 8B needs about 5 GB at Q4_K_M (recommended) and 8.5 GB at Q8_0.
How many tokens per second will the RTX 4060 8GB get on Llama 3.1 8B?
Roughly ~36 tokens/sec at Q4 in Ollama or llama.cpp.
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.
