50-60 CU's? hehe, rumor has it the high end Navi will have 80CU with HBM memory and it will use tsmc 7nm+, will have ray tracing hardware too. HBM and 7nm+ should save some power and AMD can just lower the clock slightly if needed.

Also I don't think AMD will call the card Navi, look at their roadmap, it says Navi 2019 and next-gen 2020 with 7nm+. A different name is certained.

Depends. If AMD emmploys RNDA2 on Navi 20, then possibly it will have the tracing of rays.
The rumors I have seen have pegged it at 60 CU's though... But early days yet... And grains of salt need to be taken with all rumors.

In saying that, I am keen as ducks nuts for AMD Arcturus.

Do we even know if Navi can do 3 shader engines? I don't think GCN ever could as there is no gcn gpus with 3 shader engines. And I think that in Navi that each shader engine is limited to 20CU's. You can probably do less than 20CU's per shader engine so a small gpu/apu with 12/14/16 CU should be possible.

Then it also seems when you do cut-down versions of gpus you need to disable 2CU in each shader engine so in Navi 10 you must disable 4CU's at the time so 36/32/28 CU's is only possible in cut-down versions. This is my guess.
