The chipset is on the motherboard... you do have to ask what qualifies a new gen. Was the FX-9590/9370 a new gen vs the FX-8350/8320? 14th "gen" features zero architectural changes. Even the Core 2 Duo refresh I mentioned has better claim to being its own gen. (faster fsb, etc)
You said generations to a socket, not chipsets to a socket. I'm not arguing they aren't trash, but they exist.
In any case, get a 7800x3d if you want gaming, or a 7900x for production.
That is true though, luv X3D chips for gaming.
