Discussion about the Silicone Lottery? Is there a true winner? How about a loser?

How do I know if I won the “silicone lottery”

I switch from Intel (i9-10900K) to a AMD (Ryzen 7 9800X3D)….and I been seeing this comment about silicone lottery. So there is a chance your CPU might be better? Is there a chance it could be worse? What’s the difference we are talking? I strictly use my PC Gaming.

Curious to know how one can figure this out if I am not tech savvy…..Are there any components of my PC you need to know? Is it done by using my PC normally or is there a benchmark test you can run? Just wanted to ask.

TIA
