Apple hardware uses a unified architecture. That means the CPU and RAM are integrated together: it is very difficult/impossible to strip the RAM from these systems.

This unified architecture makes Apple hardware very good for AI work, where latency between RAM and CPU is very important

Even the SSDs (which are normally more strippable) use a proprietary hardware form factor.

I think the article mentioned the real draw:

> Apple noticeably promoted the ability to link multiple Mac Studios together into a single, more capable system for running large frontier AI models, a feature aimed at business and developer customers rather than everyday consumers.
