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.
