Description : Is the Intel iMac's CPU socketed or soldered?

Last Answer : I don't know technically what the case is (I suspect socketed as it's based on standard architecture) but it's not possible to upgrade the CPU, either by yourself and definitely any Apple service ... CPU upgrades are simply not allowed and Apple has made sure that it's not possible to do so.
