I was thinking about the “new” RDNA architecture.
Facts:
1. AMD’s older roadmaps showed Navi as a new architecture. This later changed and now Arcturus or whatever the next card is called has the new architecture.
2. A rumor surfaced that the console folks (Sony/Microsoft) wanted the new GPU to be easily backwards compatible to make porting old games to it easy
3. AMD says Navi is a new architecture, call it RDNA
Interpretation:
1. It started as a clean sheet but much of GCN needed to be pulled back in to give it that easy backward compatibility.
2. Interesting name, Radeon DNA. It’s like they're trying to say it’s new, but still possess a lot of what came before.
Conclusion:
When is a “new” architecture really new, and when is it the older architecture with some major/minor updates? Can’t blame AMD for this no matter what the truth is. It’s always a thin line trying to build something new and radical while still retaining the capability to run the old stuff efficiently.
Unfortunately, this is what I expect as well but I am absolutely hoping that I'm wrong and AMD knocks it out of the park. I'm curious for the whole 9900k 2080TI vs AMD setup results, that whole thing has me scratching my head.
