There was some discussion on Twitter, and I also posted a patent that shows a long and narrow silicon bridge connecting / stacked on top of multiple graphics dies, loaded with L3 cache.
Which would bring together both of the AMD architectural home runs - partitioning large chips to chiplets and stacking.
One of the reason why partitioning never quite worked right in the past was because all the units need to work on the same image, and need super fast communication abilities between them. The active silicon bridge accomplishes it.
So the L3 would be stacked and 256 mb and 512 mb were mentioned as possibilities for RDNA3.
We don;t know how much of this will turn into reality. But there is a real chance that AMD will go as far ahead of NVidia with RDNA3 as it did ahead of Intel with Rome / Milan.
"The PlayStation 5 is Sony Interactive Entertainment's fastest selling console in its history. The console has racked up 10 million units sold, even faster than the PS4 managed to do so. Moreover, to hit this level of achievement producers/sellers/buyers have had to face speed bumps like semiconductor shortages, pandemic supply line issues, and the plague of retail scalpers."
Hopefully Sony is pretty pleased with the service they are getting from AMD semi-custom.
PS. Xbox is also doing well. From the same article:
"In its results on Tuesday, [Microsoft] claimed that the Xbox Series X/S had been its fastest selling console series to date, but we simply don't have official stats to look at and compare with Sony's. However, games industry analyst Daniel Ahmad, from Niko Partners, has provided some useful Xbox sales insight. According to the stats Ahmad has access to, "the Xbox Series X/S total sell in was 6.5m as of June 30, 2021"."
