I've seen the same story repeated in a number of places, here's as good a link as any, of a Ryzen 5 3600 AF. Basically a 5600 rebadged, but a lot cheaper. Hoping it's real, I think I'd actually upgrade if it's as cheap as rumored!
The problem is like the other AF models in the past I've found is that they're usually in such restricted supply that they're just not obtainable for the majority of value-conscious buyers.
