ID buffer and DR FP16

You mean S_STORE* ?
Among other possible differences.
The GCN3 ISA document lists additional changes from GCN2.

How the versions align might give a picture of where each element sits in the continuum. If there's a differences section for the internal docs, it might indicate how different the original GPU was.

There is a differences section, but I'm not sure I can post it in here, although there was an article by digital foundry about leaked xbox one sdk...
 
...unless it's widespread leaked enough like when the NEO presentation slides got out that the internet couldn't delete them. But... yeah. This be serious stuff.
 
Its a shame that so much has to remain hidden. Seems like it could be an interesting discussion, at least from the technical business decisions viewpoints with what practical choices were available.

I dont think either company made wrong choices, just different paths.
 
According to this GAF post, there are 2 others custom hardware features on Pro:

And apparently this feature, "texture gradient adjustement" has being patented by Mark Cerny with the name:

Gradient adjustment for texture mapping to non-orthonormal grid

Could those 2 new features be part of future AMD Navi features ? Even "Texture gradient adjustement" because of the patent ?

But we want to see these technologies put into practice. The PS2 was supposed to do things differently in a number of ways which could have brought some interesting results but we barely if at all saw anything.
The PS4 Pro is still doing things the "conventional" way. It is treated just a PS4 with a more powerful GPU

Wait future PS4 Pro first party game...

That's because PS4 must also get supported. It's the same with xb1x as the old console must get supported (which is good in my opinion) developers will optimize for xb1 and just increase resolution, texture resolution and things they already did for a PC version :)
Optimizing a title costs a ton of money and time.
Also, even if the code is not optimal for the newer architecture, it will run faster because the whole thing is faster.
 
Sounds like a sad waste of features to me
New features require R&D and requirement of being able to deliver once ou put it into production. It's why we don't see a lot of true DX12 based engines, and very little use of the DX12 feature set.

Perhaps in a couple more years.

It is those "technicalities" that make these features a waste. In the case of Direct X 12 you know it is here to stay and eventually will be used. For Pro? Things are a little more shaky. The feature support matters more now. In a few years it will matter more for PS5
