Here is the problem:

 

After Effects is not well multi-threaded to begin with. In fact, it cannot take full advantage of more than eight processing threads total. Your CPU, however, has 16 threads. That means that After Effects performance relies very heavily on both CPU IPC and high clock speeds. It just so happens that AMD CPUs have a significantly lower clock speed, even with only one core in use, than contemporaneous Intel CPUs.

 

As such, when it comes to After Effects performance, that Ryzen 7 3700X performs right in between two budget quad-core Ryzen 3 CPUs - the Ryzen 3 3100 and the Ryzen 3 3300X. That does not inspire confidence when After Effects is the only content app you're using.

      Yes. There is not much that you can do, especially since you can actually go cheap on the Ryzen 3000-series non-G line and still achieve almost the same level of performance as your 3700X for After Effects.

       

      Now, if you're running other CPU-intensive apps such as Premiere Pro, then yes, the 3700X is worth the additional power and cost.
