Hmm..

So a 5700XT is 40 CUs, 9.75 TFlops at 1755 Mhz single precision, on 7nm. It's also got a 225W TDP, which is alone at the upper end of what an entire console TDP traditionally is.

So, 12 more cores, and +70Mhz - that would roughly match up to a 12 TFlop part based on just the RDNA architecture we've seen to date. The power is the thing that really has me scratching my head. I am sure RDNA2 has some improvements over 1.0 with respect to TDP, but you are looking at a 8 Zen2 core CPU (around 45W on it's own), plus the GPU, plus the auxillary components, and all of that needs to fit within about a 250W envelope - total, for everything.

Or you make big box with lots of fans that takes up a lot of room or sounds like a jet plane... either solution consumers have traditionally hated for consoles.

It's a big leap in efficiency to get there, and no process node change to help it along. Either AMD/Microsoft is playing fast and loose with the specs (like, it's really 12TFlops half precision; although you aren't driving 8K or 120FPS anything with that really), the console is going to be nearly as big as a traditional desktop, or it's true, and RDNA2 really could be chasing nVidia - maybe not beating it, but definitely closing the gap.
