Oh I am aware its not as clear cut as that. But I also know that the move t 7nm is more significant than the move to 16nm from 28nm. I aso know that with 7nm building an APU like I have described is possible. Especially if they are aiming t have a similarly sized APU in those consoles as we do now in the PS4pro/XB1X

The Xbox One X is a "Premium" console not designed to hit low price points like the Xbox One or Xbox One S though. |
I strongly dont think the things that make the XB1X "premium" will be issues when looking at next gen hardware. First off, I dn't think the XB1X APU has anything to do with it costing more. It has a GPU with 4 more CUs than the PS4pro but the overall die size is very similar to the PS4pro APU. It using a Vapor chamber and 12GB RAM on a 384bit bus is why it costs more than a PS4pro.
I dont see them using a vapor chamber r even a 384 bit bus n next gen consoles. They just don't need to and would still be able to get performance from their components that dwarfs what we have with the Pro or the X. Eg using 12 GDDR6 chips on a 256 bit bus will still yield over 600GB/s of bandwidth or if using a 384bit bus will result in around 800GB/s. And assuming they are using the cheaper 14Gb/s/pin variant of the memory.
While I am aware f some sort of supposed 64 CU limitation with regards to Polaris we don't really know if that limitation will carry through to navi so I don't think we can just put the ceiling at 64 CUs right now.
Also the thing about conservative clocks can sound misleading. Even though you are right. Eg Say the CPU is based on an 8Core zen that ideally clocks up to 4GHz. Conservative clocks for consoles will probably bring that down to 3Ghz. Say the navi based GPU is designed to run at 1.8GHz - 2Ghz, console speeds will again be like say 1.2Ghz - 1.5hz. That is still a massive bump in performance when considering all the new components being used.

There are ways to circumvent that... I.E. Smart data streaming like you alluded to. |
Yes, and maybe those methods can be employed again next gen but I think they didn't use those methods this gen because of the weaker CPUs in the current gen consoles.
