It's not similar. It's literally the same silicon. They didn't tape out any new dies for the products branded as "14th gen"; not even a new stepping. Just minor tweaks to the binning.
I didn’t know that. I would like to know how to get more informed about these kind of structural differences on CPU generations.
Going back to the what you said, Intel selling the same silicon as two different generations (even if this is still just marketing terminology) is a bit lame on their side.
