With the announcement of the 8th-generation Core processors. Intel clearly indicated that they would need new motherboards despite maintaining the LGA 1151 socket used by Skylake and Kaby Lake processors. He claimed that there were changes in the power system of the processors that made the change of motherboards necessary. The strange thing is that he kept the same base in the process.
Intel Coffee Lake processors Power Resources
Now that Intel has released the new Coffee Lake processors, you can clearly see the differences between the two. Basically, it is used to use pins previously indicated as reserved. There is 14 more for ground (VSS) and 18 for power (VCC).
The reason why there are hundreds of power pins (391 VSS and 146 VDC) in a processor is to keep the inductance to grate in the power system (VCC). Since the pins and connections in them behave less like the ideal for an elongated cable and more like a coil. The ground pin system serves to shield and maintain the integrity of the signals received by the processor.

Hence, you have to feed with hundreds of parallel feed inputs. Which behaves just like a resistor, because in this way the processor receives a more scaled and controllable power supply to instant modifications of voltage. That can occur hundreds of times in one second. A good power system ultimately allows for better processor frequencies.
At the bottom, the big question is why Intel has not simply changed the socket to a new one with a different number of pins to avoid unnecessary confusion. The recurring question in the coming months of people wanting to upgrade their equipment will be “does my plate serve with the Coffee Lake?”
