Laptop - 16 GB RAM with ryzen 5 3500u or 8 GB RAM with ryzen 5 4500u?

I want to get the Honor MagicBook 14 and I can choose whether I use more GB of RAM or the better processor. Hence my question

16 GB RAM with ryzen 5 3500u

OR

8 GB of RAM with ryzen 5 4500u?

What's the difference really? What should I go to on RAM or the AMD processor?

I use it a lot for FL Studio and Virtual Dj and Youtube. Edit files, etc.

HAVE SELECTED THE WRONG CPU

Wanted to take the 4500u

The 4500u has 2 real cores (6 cores 6 threads) more, the 3500u 4 cores with 8 threads. Nevertheless, the 4500u is faster even in multithreaded applications.

RAM is not an argument for me, RAM can be increased, the CPU NOT.
