So I am going to post this again because I am interested in know if vgleaks could be mistaken on their assessment of Durango arch. I have done a lot of research and 2 things come to mind. Either VGleaks totally blundered on the Durango specs or they are using the wrong diagrams to prove their point. Either way, it invalidates their statements and put into question if they know what they are trying to explain to the rest of us
OK, I am quoting my own post because I wanted to make clear why it seems that vgleaks is confused about what they are saying concerning the Durango SC Unit. What could be happening here is that their diagram has the wrong terms or names which makes a big difference in how you view this content.
Here is the breakdown of the SC unit in durango from vgleaks

If you change the SIMD to CU then you start to understand why this could be a blunder by vgleaks.
Now here is where it gets interesting. This is the breakdown of the 7970 AMD card, does the diagram look very familiar

Could it be that the SC or shader cores on the Durango are an array of 4 CUs instead of 4 SIMD. If so, then the Durango has 48 Cu instead of 12. Could the Durango actually have a 7970 (actually a little better as the 7970 only has 32 CU).
