A Ryzen "7" series APU with the same 4 core / 8 thread setup as the 2400G but with double the CUs (so 22 CU) and a big beefy L4 buffer like Intel uses in their high end GPUs to be able to use the extra gpu horsepower would be game changing.
Maybe in the Navi generation? It would make for a very pretty lineup to have, say, Navi 10 / 14 / 24 be APUs, Navi 36 / 44 be a budget discrete GPU pair, have Navi 56 / 64 be shrunk Vega cards, and then some high end 2080 Ti competitor series of new cards called Navi 80 / 88[1]. If they can get power under control and have the TDPs like up like 45 / 65 / 95 / 120 / 150 / 170 / 200 / 210 / 250 watts they could have a really viable lineup no matter what Nvidia pulls...
[1] Having a GPU called the 88 would just be marketing bliss. "When we get this thing up to 88 compute units you are going to see some serious shit".
