I don’t intend to use it away from a socket so I dont want to conpromise 1% of the performance when plugged in by getting a lower power CPU that has better perf only when not plugged in.
What CPU do you have that doesn’t throttle? It’s not an Intel H, I’m guessing an Intel U version, M1, or Ryzen then.
It's not that the OP would like that, it's just how it is with Intel+Nvidia "desktop replacements". Those setups do not scale too well between workloads.
