If Amd was smart, I expect an complete SOC like RR but with the ability to connect one chiplet to it.I expect Renoir to be quad core. Until the CCX grows to 8 in Zen 3, I don't see AMD going past 4 cores.
They need to have high end APUs for the mobile, all-in-one systems and desktop.
If they really want to increase their apus margins, because with R3-3200G and R5-3400G (and respective mobile versions) they are going no where.
With 4C SOC + 1 chiplet they would get:
|SOC with CCX0||CHIPLET CCX1||CHIPLET CCX2||TOTAL # CORES|
With 8C SOC they would get:
|SOC CCX0+1||CHIPLET CCX2||CHIPLET CCX3||TOTAL # CORES|
