Actually, incorrect. On some scenarios, you’d need up to 4 CAMM2 slots to do what Apple does. This is due to CAMM2 maxing out at 128 bit busses; but M3 Max chips are currently at 512. Needless to say, battery life most affected.

Yes, the higher end Max and Ultra chips would still need soldered memory for sure. Two CAMM modules flanking opposite sides of the SOC is probably doable though, so I think the M Pros could practically have socketed memory.
