To my astonishment, there was no complete guide available which could tell clearly about the Intel processor generations and their differences. So I came home and wanted to know about the philosophy of processor generations on the Internet. I asked the person the difference between first-generation and the fourth generation but he was unable to answer properly, saying that the fourth generation was faster than the 1st, 2nd and 3rd generations.
