My realistic, most likely scenario prediction for PlayStation 4 specs and a Fall 2019 release date:

  • 64 CPU / 4096 Stream Processors GPU based on AMD "Navi" architecture
  • *This would be a ~50% increase in shader unit count from the Xbox One X GPU - not too outrageous. Along with being an improved architecture overall, it should allow PS4 to hit native 4K in all titles with no issues.

 The thing about your GPU prediction, is that as I have tried many times to point out it just doesn't make sense. Switching from 16nm to 7nm will mark a new generation of hardware all round. Even for AMD. A 64CU GPU will pretty much mark old gen tech in 2020. I mean just look at the og PS4. Going from 28nm to 16nm allowed them literally double the amount of CUs in the hardware. Literally double. And then upclocked it on top of that.

Now even if we are using the PS4pro as the new base (worst case scenario) we still end up with something that has 72CU (4608 stream processors). Now why they would do that when the same technology can be applied to the XB1X as a base is beyond me, and if they use the XB1X as a base then they end up with 80CU. Before any upclocking has been done.

All this is just doing the bare minimum that working with 7nm fabrication will allow. No envelopes have been pushed here. And if you think these all sound great? wait till you see whatever dedicated GPUs PCs will be using then. In comparison these will be lower level hardware.

Umm the specs are very similiar, I just believe Microsoft will push them TF and bandwidth speed without adding to much to the manufacturing cost to try get a slight edge over sony so they can market "The world most powerful console". The way to do it is

with slightly more gpu cores and higher clock speed than sony will go for.

They can try, but if they both release in the same year.... its unlikely.

I dont expect sony to go with the fastest gddr6 memory speed because of cost and power consumption. On original ps4 they didn't

either go for the fastest gddr5.

Sony didn't go with the fastest GDDR5 because the capacity they were using had just become available literally weeks before their PS4 unveil in feb 2013. Kinda like how Nvidias first batch of GDDR5x ram didnt go so well either.

And to hit over 500GB/s with GDDR6 over a 256-bit bus isn't even going with the fastest GDDR6. Its actually somewhere in the middle. Which is why I was saying that to go lower than that would be them going out of their way to do something they don't have to do. And don't forget, GDDR6 would be very mature technology by 2020.
