I haven't seen that 3600G. I've seen announcements for a 3400G and a 3200G, and although I'd love a APU with 20 Navi cores in it, I don't think it'll happen this time around. Maybe in a year or so.
That's true. Same amount of cores, same amount of Navi cores. Clock speeds are better and iirc cache is bigger. I'm curious as to what AMD will put in their APU's once they move them to 7nm.
