It maybe isn’t the most correct decision ever to put the 13900K and 14900K below the 12-core boundary when they’re competitive with AMD offerings of the same time period that have 16 big cores - personally, I’d count each E-core as half a core instead of zero cores for the purposes of this chart, because that seems to be about how they perform.

There’s nothing worth upgrading to from a 12700K right now if you’re a gamer, especially if you have a 3080. You’d be spending hundreds of dollars to boost your performance by maybe 5% when you could’ve just overclocked instead.

Intel will be fine. Nanometer for nanometer, their nodes are far denser than TSMC’s nodes (because process node naming is basically just marketing now), and they don’t seem to have any trouble getting new nodes up and running either.
