Cost is not actually the most questionable part. It is power. No way will Sony be wanting a 500w console.
The PS4 PRO PSU is rated upto 310W at the wall:

XBox One X PSU is rated at 245W with a 2560 shader Polaris part using a huge 384 bit GDDR5 memory bus:

It uses a Polaris based part with 2560 shaders,instead of the 2304 in the RX480/RX580/RX590 cards but with a 384 bit GDDR5 memory controller. In terms of TFLOP rating its around the same as an RX580 with 384 bit memory bus and not a 256 bit one.
Lets look at how much an RX580 consumes in power:

214W to 240W at the PCI-E power connectors. So using desktop parts as a measurement is not really indicative of what sort of power the GPU part will consume,as a desktop RX580 will not be able to run off a XBox One X PSU,despite the GPU having more shaders and a much bigger memory controller and loads of GDDR5.
The Ryzen 7 3700X is a 65W TDP part,and I expect the part in the consoles will be clocked lower with no dynamic clockspeeds(so lower TDP and power consumption). A Navi 5700XT according to AMD is upto 225W board power,and I expect again the console part will be clocked lower,and remember the consoles are being released next year,so 7NM will be in a better state and cheaper.
To put this in context my whole SFF PC system,with a 65W TDP Ryzen 5 2600,loads of drives and a GTX1080FE is well under 300W at the wall in every game. I think max was 270W to 280W.
So nah,I think its all doable in a 2020 system without needing 500W. I don't even use a 500W PSU myself,I use a 450W one which is more than Corsair used for their GTX1080 systems at 400W.
Also if Sony and MS are looking at using NVME SSDs and not cheap SATA drives,it tells you they are definitely looking to push performance a bit more than normal. Stuff like Stadia is potentially a thorn in the side of the traditional console business IMHO.
I also expect the next consoles will cost more too.
It will be quicker but take a lot of those benchmarks with a grain of salt. What were they running that 2080 at 1515mhz stock?

Its better to compare AMD to AMD,as the score for the RTX2070 is less than a Vega 64 and the RTX2070 is a faster card. A downclocked RX5700XT or an RX5700 variant should hit those scores,and the big jump in CPU performance will help a lot with higher FPS in the next generation of consoles. The Jaguar based cores are probably holding back the GPU in the XBox One X IMHO.
