The verdict
The M3 Max (128 GB VRAM) handles SDXL Turbo (GGUF) comfortably using the Q5_0 quantization, which fits in 5.0 GB. Expected throughput is around 74 tokens/second, which feels Instant — feels like typing. No noticeable delay. in interactive use. Single-step SDXL. Near-instant image generation.
Setup tutorial: SDXL Turbo (GGUF) on M3 Max
AI-generated, GPU-specific. Verified commands for your exact hardware.
The SDXL Turbo (GGUF) model runs at Grade S on an Apple M3 Max with Q5_0 quantization, achieving ~530 tok/sec.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, macOS 13.0 or later, and Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install` in your terminal.
Expected performance
With the Q5_0 quantization, you can expect the model to run at ~530 tok/sec, using approximately 5.0GB of VRAM. This leaves you with 123.0GB of VRAM for context, allowing for a practical context window that can handle very large inputs without running into memory constraints.
1. Install runtimeOllama (preferred on Apple Silicon)
brew install ollama
ollama init2. Download the model
Download the 3.5GB Q5_0 quantized model from Hugging Face.
ollama pull gpustack/stable-diffusion-xl-1.0-turbo-GGUF:Q5_03. Run it
ollama run stable-diffusion-xl-1.0-turbo-GGUF:Q5_0
ollama serve4. Optimize for M3 Max
For optimal performance on the Apple M3 Max with 128GB VRAM, use the Metal/MLX backend to leverage the unified memory architecture. Ensure that MPS layers are enabled to take advantage of the GPU's parallel processing capabilities. With 128GB of VRAM, you have ample headroom to handle large context windows and complex tasks.
Troubleshooting
Model fails to load due to insufficient VRAM.
Ensure that you are using the Q5_0 quantization, which is optimized for your GPU's 128GB VRAM. If the issue persists, try reducing the batch size or context length.
Performance is lower than expected (~530 tok/sec).
Check that the Metal/MLX backend is enabled and that MPS layers are utilized. Verify that no other resource-intensive processes are running concurrently.
Ollama fails to initialize.
Ensure that Xcode Command Line Tools are installed and up-to-date. Run `xcode-select --install` if necessary.
Alternative runtimes
While Ollama is the preferred runtime for Apple Silicon, you can also use LM Studio for a more graphical interface, llama.cpp for more control over quantization, or MLX for direct Metal integration. Jan is another option but may not offer the same level of optimization for the Apple M3 Max.
