My friend told me that macbooks have their RAMs behind the CPU (or something along those lines) and it got me wondering. Does the distance between CPU and memory really make that much difference? 🤔

The newer M-series have the RAM soldered on the board instead of removable. Typically that means they have a higher bandwidth to the RAM because of it, but you can't upgrade to more memory. It's an advantage if you're running LLMs on the unit itself, but not much use otherwise.
