Silicon lottery trumps all. That’s more important than ram and mobo.
Where ram tuning copies into play is low FPS which happen when the cpu is being stressed, having fast and manually tuned ram gives the cpu a boost to execute more under stress which means you get much better lows.
If you get bored would be curious to see if you have more headroom with SMT disabled? On Intel, you can boost higher which lower temps and lower voltage with HT disabled.
