AMD can compete in performance and power/Watt mid to high load, but is shit with low load efficiency. intel has nothing at all. Apple scales nicely over the complete range.
If you want a relatively small notebook with lots of RAM you also don't have options (not really AMDs fault, but hardware manufacturers seem to produce mostly shit now). Framework is pretty much the only somewhat decent option with 64GB max, if you want more there's pretty much only apple - which is way overcharging for that.
There are extensions for that. Which are worse than they used to be because they didn't provide APIs enabling to do that properly, about 10 fucking years after they dropped the old APIs. There are a lot of other feature requests from back then open, often even filed years before they went through with dropping the old APIs. The best way of doing custom keyboard shortcuts in Firefox is still injecting Javascript into each page, with all the shortcomings this has. Usability of Firefox is way worse nowadays than what it was 10 years ago - and I do understand (and agree) with the decision to dump the legacy APIs, but you can't just break functionality lots of people use, and not provide APIs in over a decade to fix that.
I'm trying other browsers now and then, but every single one is a dumpster fire. At least the Firefox dumpster fire is a bit less out of control - but that's the most positive thing I can say about it nowadays.
