Derbauer made this video comparing 13 7600x CPUs and what we found was very interesting. Even though all are stock and use in the same system - some of the 7600x would run 250mhz slower than the top chips and that would cost it 7% performance
But it gets even more interesting because not only is there a 10c difference in temperature between the top and bottom 7600x but also a difference in power and voltage leading to the worst 7600x having 41% less performance per watt than the top 7600x tested!
The variance here between Ryzens is huge.
To be fair however, it is likely that that there is somewhat less variance between top chips - like a 7950x, but as you go down the the stack the variances become larger
