Yes — runs locally
~46 tok/sec · Fast — smooth conversation. Responses feel real-time.
The verdict
The RTX 3080 Ti (12 GB VRAM) handles Qwen3 8B Base comfortably using the Q4_K_M quantization, which fits in 5.3 GB. Expected throughput is around 46 tokens/second, which feels Fast — smooth conversation. Responses feel real-time. in interactive use. Official Qwen3 8B foundation model — pretrained only, no RLHF or refusal training. The 'naturally uncensored' option: no abliteration needed because alignment was never applied. Apache 2.0.
Setup tutorial: Qwen3 8B Base on RTX 3080 Ti
AI-generated, GPU-specific. Verified commands for your exact hardware.
The Qwen3 8B Base model runs at Grade S on an NVIDIA GeForce RTX 3080 Ti with the Q4_K_M quantization, achieving ~92 tok/sec.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, a 64-bit version of Windows or Linux, the latest NVIDIA drivers (version 512.15 or later), and CUDA 11.2 or later installed.
Expected performance
You can expect the Qwen3 8B Base model to run at ~92 tok/sec with 5.3GB VRAM in use, leaving 6.7GB of VRAM for context. This should allow for a practical context window of around 20,000 tokens, which is suitable for most tasks.
1. Install runtimeOllama
pip install ollama
ollama init2. Download the model
Download the Qwen3 8B Base model with Q4_K_M quantization (4.8GB file size) from the Hugging Face repository.
ollama pull bartowski/Qwen3-8B-Base-GGUF:Qwen3-8B-Base-Q4_K_M.gguf3. Run it
ollama run Qwen3-8B-Base-Q4_K_M.gguf --n-gpu-layers 12 --flash-attn --context-length 327684. Optimize for RTX 3080 Ti
For optimal performance on the NVIDIA GeForce RTX 3080 Ti with 12GB VRAM, set --n-gpu-layers to 12 to fully utilize the GPU. Enable --flash-attn to speed up attention computations. With 5.3GB VRAM used by the model, you have 6.7GB of VRAM left for context, allowing for a practical context window of around 20,000 tokens.
Troubleshooting
Out of memory error during inference
Reduce the number of layers offloaded to the GPU using --n-gpu-layers <num_layers>, or decrease the context length using --context-length <length>.
Slow token generation speed
Ensure that --flash-attn is enabled to optimize attention computations. If still slow, try reducing the batch size or context length.
Model fails to load
Verify that the model file has been downloaded correctly and is not corrupted. Try re-downloading the model using the 'ollama pull' command.
Alternative runtimes
Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio is a good choice for a user-friendly GUI, while llama.cpp offers more fine-grained control over optimizations. Jan is lightweight and efficient but may lack some advanced features. For the NVIDIA GeForce RTX 3080 Ti, Ollama provides a balanced approach with good performance and ease of use.
