Repackaging with newer and higher performing fans would be one way, (like you said) they could add a couple of those and call it a day lol. And maybe optimize the fin stack to have more surface area perhaps.
True, they've gone totally complacent this gen, and tbh they shouldn't be. They might be top dog in performance now and feel like they can justify prices for their lower end stack. though Intel isn't too far behind on desktops and mobile and that's on far inferior nodes. AMD's big advantage was their smaller processes and nodes with TSMC, though with Intel are going that way with 3nm booked for next year things should get quite spicy come 2022.
I didn't know that AMD's APU's and laptops only supported PCI-E Gen 3, that's a boneheaded decision :s Way to limit your customers.
