I think even if AMD were all in for RT doing as best as they could, whatever we got in consoles would still be a subpar implementation. 95% of AMDs's eggs are in the ryzen basket. What they did with the ryzen line is probably not something they can do with radeon/navi at this point so to expect their RT implementation to rival nvidia doesn't sound likely.
It falls inline with the narrative of internal turmoil that has been around for a few months.
We have to keep in mind the windowscentral article is entirely based on the rumor that the phison e19 controller is indeed what's in xsx. Since that is a DRAMless controller MS wouldn't be affected by the dram price hike, for the ssd. They still need ram chips and nand, and both are going through price hikes which are likely NOT affecting either console.
This is my issue with the idea that dram prices/shortages happening now, affect consoles. Remember years and years of confirmation that sony/ms get their contracts and prices set long in advance? That means whatever market fluctuations happen, they would be unaffected as their price/quantity is already locked in. We know TSMC and likely other foundries/manufacturers set allotment of chips long ahead, right? So whatever sony/ms need, that quantity is guaranteed for them unless they underestimated their needs, at which point yes, they're affected.

There isn't a single original thought or idea in the article and the few times a source is mentioned, it goes back to something written elsewhere.
