Year of manufacturing says nothing; you can have two different gens manufactured in the same year, one for lower price tier and the other for the higher one. Just like Apple still produces older iPhones, same thing. Instead, you have designations like "Intel Core i7 8565U Whiskey Lake" or "Intel Core i7 10510U Comet Lake". The first one is 8th generation (=8xxx), the second one is 10th generation (10xxx, but the 14nm one, not the 10nm "Ice Lake"), and most OEMs do put these into their marketing materials and they are on their respective web shops (these two specifically were copied from two different Thinkpads X1 Carbon models).
