PS4 Neo GPU Is Point-For-Point A Match For RX 480

I'm convinced that Google crippled their search algorithm in a meaningful way. There are certain quotes, articles and discussions that I've had trouble finding within the past few months as well.

WOW, I'm glad someone else noticed. I'e been complaining about this to my son for a couple of years now. I used to be able to find things quickly but now it just fills my search with newer stuff even if it only vaguely resembles what I'm actually looking for. I got an answer on GAF by the way adn it turns out I'm right:

Yes, later GCN revisions (1.2 onwards I think) used the 8 x 8 = 64 compute sources. PS4 was early to that, kind of like Xenos sat between gens.
Makes me wonder, the PS4.5 may look very 480ish, but what Cernyizations are in there?

ME:

Thanks. I'm really not technically minded at all so I didn't have a clue what to search for. Wouldn't the question be: if indeed AMD made those changes internally, would they be available only to chipsets made for Sony or would they be more widely available? Could Sony have patented those changes?

These fall under AMDs new semicustom strategy - Sony may have highlighted the need, but AMD is still doing the bulk of the engineering. Sony has engineers of their own no doubt, but I think anything would be cross-licenced at most (think Toshiba using Cell for whatever, or Xenos being first to unified shaders but ever new GPU after it using them).

Sony gets hardware ahead of current roadmaps out of it, AMD gets part of their R&D funded.

Another answer:

Cerny wanted more engines capable of distributing graphics vs non-graphics work. The idea is essentially getting better utilization and getting closer to the peak performance of the APU. It was no coincidence that the CPU was quite weak so the GPU could also help out with the compute related tasks.

It will also come in play for VR, which is why I've been saying that they will be doubled in Neo/Scorpio.

Trust me, as someone who loves having citations to back up their statements, oh yeah. I've noticed lol.

 

This also seems to confirm my thoughts regarding the weak CPU relative to GPGPU compute. Not so secret sauce confirmed
