They need a high volume mainstream to value APU primarily for mobile and secondarily for desktop . Something plentiful and cheap to produce, similar in ~5B transistors as RR.Why would they ever do that?
They could ride it out with a RR optimization and binning refresh, but that means no significant frequency improvments and no IPC improvements over a 2400g.
It would be nice if they could take some of those Zen2 improvements, namely, the integer core related ones and port it to 12nm. A RR successor really doesn't need to waste transistor on massively overkill FPUs or a large number of huge multilevel caches that need to talk to another.
