Can NVIDIA GeForce RTX 4070 SUPER run Llama 3.1 8B?

8B parameter LLM model on 12GB GDDR6X

Yes — runs at 8-bit quantization
~37-45 tok/sFast
SpeedFast inference, near-native speed
QualityNear-lossless — virtually identical to FP16

VRAM Requirements

Llama 3.1 8B is a 8B parameter model. At full precision (FP16), it requires 16GB of VRAM. Your NVIDIA GeForce RTX 4070 SUPER has 12GB, so you'll need to quantize it to 8-bit (Q8) to fit.

FP16 (Full Precision)16GB (need 4GB more)

Maximum quality, no quantization

Q8 (8-bit)8GB (4GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)5GB (7GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 12GB GDDR6X at 504 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

Running Llama 3.1 8B at 8-bit quantization on NVIDIA GeForce RTX 4070 SUPER gives you virtually identical quality to full precision while using roughly half the VRAM. Most users cannot distinguish Q8 output from FP16. This is the recommended precision for daily use — it's the best balance of quality and resource usage.

How to Set It Up

Step 1: Install Ollama

curl -fsSL https://ollama.com/install.sh | sh

Ollama is the easiest way to run local LLMs. Works on Linux, macOS, and Windows.

Step 2: Download and run Llama 3.1 8B

ollama run llama3.1:8b

This downloads the model (~8GB). First run takes a few minutes.

Step 3: Verify GPU is being used

nvidia-smi

Check that VRAM usage increases when the model loads. You should see ~8GB used.
