In one place they put "14nm Finfet", another place "14nm SoC". Weird

Not really. Summit Ridge is a CPU-only part -- no graphics, so not exactly a SoC by definition. Everything else is APU's in one form or another.

Zen is not delayed. This roadmap is about "PRO" products. They always are commercialized after consumer parts.

Obviously it is a 14nm Planar Fd-SOI process. A shrink of FDX22.

!!!

obvious sarcasm is obvious

A group of CUs can be any amount. I believe even a lone CU can count.

P11 could be 5+5+5+1 if AMD wanted it to be. Although that would be stupid.

A core complex might be tightly integrated, similar to CUs in the GPU, where there are also no half enabled CUs. Of course, a CU contains much less logic.
These days we have AVFS and power gating at the granularity of individual core anyway. I don't see why they would go backwards and throw away that flexibility. So selling parts with fused-off cores would hardly not happen.

This could be related to metal layers. Aside from transistors they might use less dense layers for somewhat higher clock frequencies in a CPU, or denser ones for APUs with large part of it being GPU.

Still it is weird to put Finfet when it should be CPU.

Also the AM4 parts shouldn't be called SoC either as they require a southbridge (Promontory).

AMD clearly makes these distinctions on their website between SoC and APU.

SoC versions have the chipset integrated.
APUs require a chipset.

Actually they have an integrated SB but not with as much ports as Promontory, that s a smart choice as it s easier to upgrade an external SB than the one in a SoC...
