@Mahigan Haven't seen you respond to this?
"Slide 56 tells you what it can do 9 devices, 8+1 compute and graphics respectively and in queue 64+
yeah it has the same limitations as Maxwell 2 when it comes to register pressure slide 34
However, the new architecture is more susceptible to: register pressure
using too many registers with a shader can reduce the maximum waves per SIMD
This is a direct quote from that slide
then it gives a table to clarify this
Maxwell 2's AWC's and AMD's ACE's are setup similarly, I think the slides talking about the cache which is like how CPU's cache works is what misled you. The reason for this is because the APU's would need this.
This slide deck should be available on line for everyone.
"Any case Fury X seems to come in at around the 980 ti performance wise in this early bench from AOS, so unless there is some magic sauce for the r290x, lets put this down to Fiji and maxwell 2 drivers aren't as mature in Dx12 yet. And AMD's Dx11 drivers were just forgotten about."
