I’ve never bothered to look at my own computer before, so I just did a test. I have a 4790K with 16GB and a 2070Super on an old MSI Gaming 5 MB.
Of my 8 logical CPU’s, while flying, I have one running at 90% consistently, 2 running around 60% and the other 5 between 30 and 40%.
So we may be discussing semantics here. (And yes, I’m going to call them CPU’s from now on 
).
To one person, that may be evenly spread, to another, that could be considered one CPU running really hot compared to the rest. The point is, one logical core is carrying a huge load compared to the others.
I also want to point out, I have xCon running, Task Manager, and at least 50 Firefox tabs going, and at least 100 other programs running, so who knows where all that processing is going…
