The interface for connecting the processing unit to the motherboard is a defining factor for compatibility. The machinery uses specific socket types that dictate which processor models it can accommodate. Therefore, ensuring the socket type matches between the motherboard and the new processor is paramount. Other factors such as 'speed', 'core count', and 'cache' pertain to performance and secondary compatibility checks rather than primary physical and electrical compatibility.
