I think there are important pieces of info that are missing.
That dude from microsoft, phil spencer, said the seX will be twice as powerful regarding graphics, compared to 1X right? The 1X has a 6tflop rx580 with more bandwidth to accomodate the fake 4K/30fps most games feature (dynamic res, checkerboarding, half res, you name it).
People assume that twice 1X gpu performance, means 12tflops, but alas the 2070 super is twice as fast compared to rx 580, with only 9 tflops.
MSI's GeForce RTX 2070 Super Gaming X is a factory overclocked custom-design that's priced only $10 higher than the Founders Edition. It is cooled by a large triple-slot, dual-fan heatsink that has fan-stop and runs cooler and much quieter than the NVIDIA Founders Edition.

Also what about die size. Rx 5700xt is already 251mm^2 without RT and without the cpu cores. How big will this APU be? What is its transistor budget?
I mean look how much bigger the turing gpus ended up, just by adding RT. Do we really think that AMD has gotten so smart all of a sudden that they can even match Nvidia's know how? Will RT be based on other computing units? And what will happen to that computing unit's processing power, when it will be executing RT commands? And what about power draw?
Also is AMD going to just kill off their own mid range category? How are they going to sell their rx 5500s if they are useless?
I don't know, it seems to me that there is a bit of exaggeration of what we should expect.
Just a reminder, we were promised Babylon 5 graphics for nintendo 64, we were supposed to get toy story 2 graphics with the original xbox, quoted by Billy the kid himself, and don't get me started on what Sony was showing at E3 2006...
