It seems my prediction of 6-core CCX for Zen2 has been just killed. Either AMD is going for 8-core CCX modules or will maintain the same 4-core configuration and will add four CCX modules per die.
I think 8-core CCX modules and two modules per die is a better technological solution. This also means that the Zen2 APUs for mainstream would be up to 8-core.
The quadrupling of L3 cache per CCX could help to mitigate the latency problems when accessing main RAM, but in the other hand, this seems to imply that Zen2 core size will be similar to Zen. I wonder if most of the IPC gains for Zen2 will come from the larger L3.
