First off, "up to" is the most bullshit metric. I am also up to 10x more productive when I get coffee, but that's when comparing to days where I just play Satisfactory all day long.
Secondly, "compared to a random HP AIO PC with a 5 year old CPU" (since there are approximately zero chances that the most popular PC in a market that is heavily Apple dominated would be a 2023 Raptor Lake) is just, once again, Apple's piss poor comparisons.
