Because Apple is soldering ram next to the chip, it enables them to make their RAM a lot faster.

What a bullshit I see.

Of all the points in their blatantly wrong comment, this probably wasn’t the one to single out. The reason for the soldered RAM is due to speed and length of traces. The longer the trace, the more chance there is for signal loss. By soldering the Ram close to the cpu the traces are shorter, allowing for a minuscule improvement in latency.

To be clear, I don’t like it either. It’s one of the major things holding me back from buying a MacBook right now.

Same way itx boards are preferred for ram oc. But i doubt apple is pushing crazy timings and clocks.

Exactly. There is an actual, tangible benefit of doing it that way. I don’t like it, as it creates situations where you’re unable to upgrade your own hardware, but it does make sense for the 95% of the population who has never opened a laptop, let alone tried to replace ram

The longer the trace, the more chance there is for signal loss.

While this is true on paper, we don't need to pretend that this is an unsolved problem in reality. It's not like large-scale motherboard manufacturers simply refuse to put their RAM closer to the CPU, and it's littered with data loss. Apple also didn't do anything innovative by soldering the RAM onto their motherboards. This is simply bootlicking Apple for what's actually planned obsolescence.
