Dolphin is plenty optimized in the x86-64 JIT. I guess you haven't actually looked at the code huh. You're running a CPU that was based off AMD's god awful Bulldozer / Vishera arch. One of AMD's worst designs ever for single threaded perf, which any emulator needs.
Last Story is also one of the most demanding titles to run in Dolphin, so much so that it even lags significantly on a real Wii.
most Ryzen CPUs are fine (Disclaimer, on the latest development build). Your HD 6450 is also fine on Direct3D or Vulkan backend. Just get rid of the FX-8300 or overclock it to the moon if you want any reasonable performance in Last Story.
GC games are no less demanding than Wii games for the most part. GC and Wii is mostly the same hardware with some small clock speed differences (Which is mostly irrelevant because we emulate an infinitely fast GPU). So it all depends on how the game works and what it does that determines how much it taxes your CPU.
