You're taking one generation and ignoring some aspects of the performance gain to make a blanket statement about the Zen era.
The 5600X gained up to 50% performance in gaming, that's the umpteenth time i've had to bring that up because you keep forcing the issue.
The Ryzen 1800X, launched in 2017 scored 3,587 in R20, a very respectable score given the best Intel had at the time, the 7700K scored 2,257.
The Ryzen 5950X, launched in 2020, 3 years later, scored 10,448, a 291% increase over AMD's flagship mainstream from just 3 years earlier.
