I was wondering if it would be possible to put the CPU on a different PCB than the rest of the Mainboard? Then you would interconnect the Mainboard and the CPU via some connector that has a high enough bandwidth to do the job (is PCIe enough? I don’t know). Since we can’t have sockets for CPUs in laptops, this would allow one to upgrade the CPU without have to replace the entire Mainboard?
You could imagine doing the same for soldered RAM modules, if you can afford the room to have SO-DIMMs, simply replace the PCB with the RAM modules for bigger ones?
I’m sure there is a technical reason as to why it’s not feasible otherwise it would have been done, but I searched and can’t seem to know how to phrase it properly, so I can’t find the answers
Thanks in advance!
