Can RTX 4070 Ti SUPER run Qwen3 8B Base?
Yes — runs locally
~70 tok/sec · Instant — feels like typing. No noticeable delay.
The verdict
The RTX 4070 Ti SUPER (16 GB VRAM) handles Qwen3 8B Base comfortably using the Q4_K_M quantization, which fits in 5.3 GB. Expected throughput is around 70 tokens/second, which feels Instant — feels like typing. No noticeable delay. 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 4070 Ti SUPER
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Qwen3 8B Base on an NVIDIA GeForce RTX 4070 Ti SUPER with Q4_K_M quantization for Grade S performance at ~123 tok/sec.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, a compatible operating system (Windows or Linux), the latest NVIDIA drivers (version 525.60.12 or later), and CUDA 11.8 installed.
Expected performance
With the Q4_K_M quantization, you can expect ~123 tok/sec performance, using 5.3GB of VRAM. Given the remaining 10.7GB of VRAM, you can achieve a practical context window of up to 32768 tokens, allowing for long and complex conversations.
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).
ollama pull bartowski/Qwen3-8B-Base-GGUF:Qwen3-8B-Base-Q4_K_M.gguf3. Run it
ollama run Qwen3-8B-Base-Q4_K_M --n-gpu-layers 32 --flash-attn --tensor-parallelism 14. Optimize for RTX 4070 Ti SUPER
For optimal performance on the NVIDIA GeForce RTX 4070 Ti SUPER with 16GB VRAM, set --n-gpu-layers to 32 to utilize most of the GPU memory while leaving some headroom for context. Enable --flash-attn for faster attention computation and set --tensor-parallelism to 1 for single-GPU operation. This configuration will allow you to achieve ~123 tok/sec with 5.3GB VRAM in use, leaving 10.7GB for context.
Troubleshooting
Out of memory error during inference.
Reduce --n-gpu-layers to 24 or lower and decrease the batch size if applicable.
Slow token generation speed.
Ensure that --flash-attn is enabled and check your CUDA installation for any issues.
Model fails to load.
Verify the integrity of the downloaded model file and try re-downloading it.
Alternative runtimes
Alternative runtimes like LM Studio, llama.cpp, and Jan can be used for more advanced configurations or specific use cases. LM Studio offers a graphical interface and is suitable for users who prefer a GUI. llama.cpp provides more control over low-level optimizations and is ideal for fine-tuning performance. Jan is a lightweight runtime that can be useful for quick prototyping or testing. However, Ollama is generally the easiest to set up and use for most users on the NVIDIA GeForce RTX 4070 Ti SUPER.
