You're listening too much to the biased Apple marketing, BSing you with comparisons to years old Intel CPUs locked into poorly cooled chassises on their laptops (they compared it for Intel MacBook Air ffs).
The new AMD and Intel CPUs are fine. There's a reason Apple never dares to mention them in their marketing shows - they always ignore things that are competitive.
Your FOMO reaction is exactly the emotional reaction their ads are meant to trigger - they're dialed in to manipulate you into this feeling to feel bad about not owning their products.
