Goodby Teraflop (PS5 and Xbox Scarlet probably will not contest on Teraflop number anymore) expect 8 to 9 teraflop for PS5 and Scarlet

I remember MS saying that scarlet would be 4x more powerful than one X. But I dont have idea what it means, seems that is not in Tflops.

Also, I remember Xbox launching with 1.3Tflops, and PS4 with 1.84, and they were almost the same visually. Better frame rate in one, better resolution in other, but they were par. Seems that 8 to 12 Tflops would be the same situation. 4 Tflops (a PS4 pro) of difference and the machines would still be on par.

There will be a difference but not much and difficult to see, unless exclusives games or games made for specific console. 

Scarlet  4X more powerful than Xbox One X probably means the total performance and combination of  CPU, RAM and GPU. The GPU alone probably less than or equal 2.5 times. Also the number will be different and need to be translated to Navi (RDNA/RX 5000 ) teraflop number because Navi will have less teraflop but more efficient on performance (1 teraflop Navi/RDNA is 1.5 X than GCN GPU ). Xbox Scarlet is 2.5 X 6 teraflop = 15 teraflop GCN number but remember we will need to translates to Navi teraflop number, Scarlet GPU will be 15 tf : 1.5 performance gain of Navi = 10 RDNA for Scarlet.  That's just for the GPU alone. 

If we are doing the right way, 4x more performance would be each component at least 4x more powerfull/efficient/etc. It isn't sum or multiplying each gain. It is more likely that the worse component needs to be 4x higher.

Trust me i would love to get more CU and more teraflop on PS5, but the reality is Navi GPU die is bigger compared to Vega even on the same 7nm process, and even 36 CU of Navi 10 (RX 5700) the transistor is double than 36 CU on PS4 pro. Also  do not worry the performance of even 7 to 8 teraflop of Navi is equal to 12 to 13 teraflop GCN (PS/PS4 Pro). Not include low level API and optimization that will bring out extra power for PS5 final performance.

But I do believe like you said PS5 were actually planned to release on 2019 but they are canceled and change to 2020 waiting for mature process to 7+ nm or 7 nm EUV process to get  44 to 48 CU fit inside PS5 APU and have 10 to 11 teraflop in compute performance (so in GCN number it's transale to 15 to 16 teraflop) and equal or more than RTX 2080 and close to 2080 Ti. But this is just my assumption, many forum dwellers in resetera and 3D forum are also still in debate weather PS5 will be using smaller Navi 7+ nm chip (7 nm EUV process) to fit more CU and have less power consumption and low temp. We can just cross our finger and hope for it.

But Alas Teraflop is not everything , as long it perform slightly better than RTX 2070 or close to RTX 2080 this console is already super beast even for 499 USD. Just let lower our expectation to reality so if it's in the end PS5 is getting 48 CU it will make us even happier due to our less expectation.  

NEVER! I know PS5 will be a 64 CU BEAST!

Not 64. We will have a dual SOC with at least 80 CU, perhaps 112.
