For RAM, yes. Soldering it down right next to the CPU allows for lower voltages and faster bus speeds. For SSDs, it's more difficult. It surely makes no difference for standard PCIe, there's really no excuse to solder that one to the board. I'm actually not sure how exactly SSDs work in a MacBook M1/M2. I think it's plain NAND storage soldered directly onto the board, with the controller in the M1/M2. I have no idea about power savings here, but it sure is fast...
- LoganDark 3y agoFor RAM I think even the trace length on the motherboard matters but this is just a reason for why the sockets are usually near the CPU, not a reason why you would have to eschew sockets altogether.
