If M1 laptops had user-upgradable RAM and SSDs?

[ThomasJL]

If the M1 MacBook Pro line had used industry standard sized RAM and SSDs, then they would be user-upgradable. (This was how the MacBook and MacBook Pro lines were under Steve Jobs’s leadership.)

So here’s my question:

How much of a performance difference do you think there would be between (for example) a current built-to-order M1 MacBook Pro with Apple’s soldered-on RAM and soldered-on SSD, versus a hypothetical upgradable M1 MacBook Pro with the exact same specs with the only difference being that the same sized RAM was the latest top-of-the-line Crucial brand and the same sized SSD was the latest top-of-the-line Samsung brand?

Not normally. Just cheaper. But with this whole system on a chip thing now, I'm not sure how it works.

LPDDR isn’t available on sticks.

One of the reasons low power ram is possible that it’s not in a socket.

Steve Jobs didn't have an viable option for RAM on a CPU chip. See this StackExchange discussion from just six years ago:

Why is RAM not put on the CPU chip?

Modern CPUs are very fast compared to all things external, including memory (RAM). It is understandable, since CPU clock frequency has reached a point where it takes several clock ticks for an el...
