I doubt they will go full on "discrete chips" like in PS3, but I expect them to use several CPU/GPU modules on a single package/under a single heatspreader, like AMD does with their EPYC line up of server CPUs. Rumors have been going strong for years that Navi will not be a "single big chip" design, but a modular approach with several smaller modules connected by "infinite fabric" (ultra high bandwith connection), that "act" like a single chip. This has the advantage that the smaller modules reach far higher yields than big chips, so this design should be cheaper to manufacture if the "infinite fabric" itself isn't too costly.
I could see a 2019 PS5 using 2 Zen CPU modules with 4cores+HT each and maybe 4 Navi modules with 18CUs (=1152 shaders) @ 1100MHz each for 10TF FP32 theoretical performance.

Infinite Fabric may very well play a part in the PS5. There are so many technologies they can use, and that is what makes the next gen so exciting.
But, Man Alive, a 10TF GPU. I am hoping the baseline PS5 is closer to 20TF. PS5 should be a generational leap over PS4, not just a PS4 revision.

1,6ghz Jaguar -> 3ghz Zen core = ~4x speed up? in terms of cpu.
1.84 Tflops (sea islands) -> ~12 Tflops (Navi) = x6-7 speed up? in terms of gpu.
GDDR5 -> GDDR5x or GDDR6.
That would be a big enough jump imo (ps4 -> ps5).
4k wouldnt be a issue.
Also I seriously double this launches before Holidays 2019.
