The 5-nanometer process is more advanced than the 12-nanometer process, with lower energy consumption and faster speed. The chip, also known as the integrated circuit, was invented by an American engineer named Kilby in 1957. Before the invention of the integrated circuit, electronic products were designed with electronic tubes or transistors. They are then welded together with very thin wires to achieve a special function, which is the most primitive chip (integrated circuit). So the (chip) integrated circuit is actually a circuit that integrates a large number of transistors, and now the (chip) integrated circuit is very advanced, we can directly make a large number of transistors on the silicon chip (chip), to achieve super powerful computing power
The difference is very big, can put more than twice the components, the performance must be improved a lot.
