DGX Spark and Mac Mini for Local PyTorch Development

Read Original

This article provides a technical comparison between the DGX Spark and a Mac Mini M4 Pro for local PyTorch development, specifically for LLM inference and fine-tuning. It includes performance benchmarks for a custom 0.6B parameter model, highlighting the DGX Spark's superior performance (comparable to an H100) and its advantage of 128GB VRAM for larger models, while discussing PyTorch MPS limitations on Mac.
