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.
Yes that's because they don't price match.
If they would, the Apple computer would still some better things about it but it wouldn't win a lot of benchmarks, if any...
_No-one_ buying this is upgrading from an M3. Honestly, most people buying this would be upgrading from some sort of elderly Intel thing; these tend to have long operating lifetimes.
Now 4 generations in, they are still comparing performance to M1. I get that 15-20% improvements aren't too exciting but it feels old.
