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...
After the appstore fight, DHH's favorite is whatever is not Apple lol. TBF it just opened his eyes to alternatives now is happy off that platform.
How long until he clashes with the GPL and discovers the BSDs?
Why would that happen? The GPL doesn't conflict at all with anything 37Signals does nor the Rails ecosystem...
Now, but after listening to podcasts with him I think he's someone who would tackle hard stuff like drivers or DSP, so called math genius level coding as soon as it becomes more accessible for him through AI assisted coding.
There is a chance to build a real MacOS/iOS alternatives without a JVM abstraction layer on top like Android. The reason it didn't happen yet is the GPL firewall around the Linux kernel imo.
What app store fight?
