If we compare a 4.7GHz i7 8700K with a 4.0GHz Ryzen 5 2600X, we will notice that for 17.5% higher frequency, the i7 is 50%, 43% and 41.6% faster.
If we compare a 4.7GHz i7 8700K with a 4.1GHz Ryzen 7 2700X, we will notice that for 14.6% higher frequncy, the i7 is 21.3%, 18.7% and 19.6% faster.
In this extreme case, when the application obviously doesn't favour any Ryzen, a 15% IPC uplift and 20% higher frequency coming with the 7nm, things will be pretty much equal.

I don't know why you would use a wildly out of the ordinary chart like this to make the point that you are, but for one even with those quoted improvements Ryzen 3000 would still be slower than Coffeelake in this benchmark and what's more we are not going to see 15% IPC improvements and 20% higher clocks.
