Microsoft: Xbox Series S and X only next-gen consoles with full RDNA 2 feature set

Only Xbox can do sampler feedback, mesh shaders, and variable rate shading. 

If these things are indeed part of DirectX12, then that explains why MS would know for a fact that PS5 doesn't have these things. 
But regarding PR, they said "Xbox Series X|S are the only next-generation consoles with full hardware support for all the RDNA 2 capabilities AMD showcased today."

Did AMD showcase every feature of their chip on that particular day?
If they did, then again, that could just mean DirectX. If they didn't, then PS5 could have more of the features that AMD chose for their solution than Xbox.

Not that that matters anyway, because all three were developed alongside each other, at the same time, and all three chose the solutions that best suited their environment. With perhaps the exception of DirecX since that's Microsoft's tech.

AMD confirmed full RDNA 2 were as PS5 is “custom RDNA 2”. To me that’s PR for “some but not all features”. 

Seems like you haven't read any of my posts?
Xbox is also custom RDNA2. And it doesn't sound like you know what 'full RDNA2' means here, so please read my posts, and refute anything I said if you think anything sounds inaccurate. And explain why.

Remember when Xbox One S won 2 NPD's in a row and they made that commercial stating "the best selling console in the US"? Even though PS4 had sold several million units more. Technically their statement was true. But it was all about what they left out of that statement. And it's essentially the same thing here.

AMD's chip is not a standard that Xbox and PS5 strive to follow. They all developed these technologies together at the same time. But because only AMD named theirs "RDNA2", it can sound that way when Xbox and Sony's chips are described as "RDNA2 based". In reality RDNA2 is also XSX and PS5 based.
Because as Mark Cerny pointed out, AMD may use some of the features that were developed for PS5 (and Series X).

They all chose what was best for their solution. Xbox and PS5 being consoles with set hardware gives them the opportunity to do things with their chip that isn't feasible for a PC GPU that has to account for a wide variety of hardware configurations. That's why Sony's and Xbox's chips have more features.

Sorry I don’t read all posts. And I’m not a technical guy. It’s all up in the air I suppose but putting the various little pieces together it’s a odds-stacked-against-Sony bet that the PS5 RDNA is superior to what Xbox is packing. Seems to me they put most of their cost into the SSD and controller redesign where as MS simply has in-house tech that’s cutting edge.
