Which processor to choose for MariaDB?

Question

MySQL

Hello!
Can you please tell me how much it makes sense to choose a multi-core processor for MariaDB? How is it with multithreading? For example, which is better FX-8370E or Opteron 6172? (in both cases ECC memory). Or, for example, take something like Ryzen, where the performance per core is higher and the entire load will be single-threaded?
Requests are predominantly for writing.

FX-8370E, IMHO. But only IMHO. The level of the rest of the iron is cheaper, but the service life is shorter.
