I think DHH compares them because they are both the latest, top-line chips. I think DHHs benchmarks show that they have different performance characteristics. But DHHs favorite benchmark favors whatever runs native linux and docker.

For local LLM the higher memory bandwith of M4 Max makes it much more performant.

Arstechnica has more benchmarks for non-llm things https://arstechnica.com/gadgets/2025/08/review-framework-des...
