It's lose-lose
Ryzen 3600 over Ryzen 1600 is 20-30%, for two generations. For two generations, this is nothing.
Slightly better than what Intel offered with 3770 over 2600, 4770 over 3770, 5775C over 4770, 6700 over 4770. And for what it was so hated.
And your performance is constrained by the number of threads, not by their individual speed.
2600K vs 3770K was 10%
3770K vs 4770K was 5%
4770K vs 6700K was 20% (switch from DDR3 to DDR4)
The performance difference between my 1600 and 3600 is 30%.
