with zen APU (7nm) with 2 X 6 cores = 12 cores with 24 hyper threading enable , and 1 core reserved for with core clock 3,2 Ghz
24 to 32 GB GDDR6 or HBM3 700 Gb/second
Navi based GPU (7nm) with 112 CU (compute unit) with core clock 1550 mhz and can achieve 22 teraflop
2 tera byte hybrid HDD
USB 4.0
Bluetooth version 4.0
2 x USB version 4.0
C-USB or thunderbolt port
Ethernet port
Wireless
Dual layer BD ROM disc up to 60/ layer = 120 GB total , and speed 12 X
DVD Rom speed 24X
CD Rom speed 36X

And price 500 to 550 USD , i don't mind 

That would consume at least twice as much power (350 - 400 W) as the original PS4 and come with a series of technicalities which would make it even harder to release, such as an external PSU, water cooling, miss the more efficient energy labels  class etc. and overall make the fat PS3 anbd Xbox One X look like sensible, small, cheap consoles. I don't think you really thought this through. It will be half that which you expect, but maybe a PS5 Pro version from the early to mid 2020s will match those specs though.
