AI-generated, GPU-specific. Verified commands for your exact hardware.

TL;DR

The Llama 3.2 1B Instruct model runs at Grade S on the NVIDIA GeForce RTX 4070 with FP16 quantization, achieving ~247 tok/sec.

Prerequisites

Before starting, ensure you have at least 2.3GB of free disk space, a 64-bit version of Windows or Linux, the latest NVIDIA drivers (version 525.60 or later), and CUDA 11.8 or later installed.

Expected performance

You can expect the model to run at approximately 247 tokens per second, using around 2.8GB of VRAM. With 9.2GB of VRAM remaining, you can achieve a practical context window of up to 131072 tokens, which is sufficient for most tasks.

1. Install runtimeOllama

pip install ollama
ollama config --device cuda

2. Download the model

Download the FP16 quantized model (2.3GB file) from Hugging Face.

ollama pull bartowski/Llama-3.2-1B-Instruct-GGUF:Llama-3.2-1B-Instruct-f16.gguf

3. Run it

ollama run --model Llama-3.2-1B-Instruct-f16.gguf --interactive
ollama chat --model Llama-3.2-1B-Instruct-f16.gguf

4. Optimize for RTX 4070

For optimal performance on the NVIDIA GeForce RTX 4070 with 12GB VRAM, use the FP16 quantization. Set --n-gpu-layers to 32 to utilize the GPU effectively. Enable flash attention with --flash-attn to reduce memory usage and improve speed. With 2.8GB VRAM used by the model, you will have 9.2GB of VRAM available for context, allowing for a practical context window of up to 131072 tokens.

Troubleshooting

Out of memory error during inference

Reduce the number of GPU layers with --n-gpu-layers 16 or enable flash attention with --flash-attn.

Low token generation speed

Ensure that CUDA and the NVIDIA drivers are up to date. Try increasing the batch size with --batch-size 16.

Model fails to load

Verify that the model file is correctly downloaded and not corrupted. Re-run the download command.

Alternative runtimes

Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio is a good choice for a user-friendly interface, while llama.cpp offers more control over quantization and optimization. Jan is suitable for cloud deployments. For the NVIDIA GeForce RTX 4070, Ollama provides a balanced approach with ease of use and performance.
