Apple would require multiple LPCAMM2 modules to provide the bus width necessary for their chips. Up to 4 x LPCAMM2 modules depending on the processor.

The size of each LPCAMM2 module is almost as big as the entire size of an Apple CPU combined with the unified RAM chips, so putting 2-4 LPCAMM2 modules on the board is completely infeasible without significantly increasing the size of the laptop.

Remember, the Apple architecture is a combined CPU/GPU architecture and has memory bandwidth to match. It's closer to your GPU than the CPU in your non-Mac machine. Asking to have upgradeable RAM on Apple laptops is akin to almost like asking for upgradeable RAM on your GPU (which would not be cheap or easy)

For every 1 person who thinks they'd want a bigger MacBook Pro if it enabled memory upgrades, there are many, many more people who would gladly take the smaller size of the integrated solution we have today.

Can I please have upgradeable RAM on GPU? Pwetty pwease?

Sure, as long as you're willing to pay in cost, size, and performance.

The non-Pro/Max versions (e.g. M3) uses 128-bits, and arguably is the kind of notebook that mostly needs to be upgraded later since they commonly come with only 8GB of RAM.

Even the Pro versions (e.g. M3 Pro) use up-to 256-bits, that would be 2 x LPCAMM2 modules, that seem plausible.

For the M3 Max in the Macbook Pro, yes, 4 x LPCAMM2 would be impossible (probably). But I think you could have something like the Mac Studio have them, that is arguably also the kind of device that you probably want to increase memory in the future.

It would only need to be 2x per board side.
