This also confirm Navi 10 will able to achieve 1.8 teraflop LOL. So it aligned with Digital Foundry .

Like I said i don't fully believe final consumer PS5 will be 14,7 TF, probably 12 to 13 , because  Digital Foundry analisis said that. Based on Price leak also it will not be expensive, also it has been confirmed by AMD Navi 10 will be a new mainstream GPU.  All GTX 1080 and Vega 64 will be a new mainstream GPU standard 

Navi 10 = GTX 1080 + 15 % is actually believable , what else do you expect ? 

Also, I just found this in a PC Gamer article about Navi:

"Looking at the Vega 64 vs. Radeon VII core size, we can get at least a reasonable estimate of what can be done. Vega 10 (Vega 64) at 14nm is a 486mm^2 die with 12.5 billion transistors, Vega 20 (Radeon VII) at 7nm is a 331mm^2 die with 13.2 billion transistors. That's 32 percent smaller with 6 percent more transistors. With similar scaling, AMD could end up with a 200mm^2 die with 40-48 CUs (2560 to 3072 streaming cores). Toss in higher clockspeeds and lower power consumption, with more memory bandwidth thanks to GDDR6, and the top Navi 10 part could be competitive with RTX 2070."

PC Gamer says they are expecting between 40 and 48 CU's for Navi 10. Based on the scale in Digital Foundry's video, that would be 9.2 tflops for 40 CU's and 11.1 tflops for 48 CU's. So yeah, I wouldn't expect more than 11.1 tflop for PS5 if I was you, unless Sony decides to wait on Navi 20's release in 2020 instead of using Navi 10. 

Then also "  Tum Apisak "  leak that mentioned by Digital Foundry and Adored TV guy, they  agree about the performance of navi 10 will be around  Vega 64 + 15% , While Digital foundry said 1,8 Ghz with 64 CU  will be around 14,7 teraflop, 60 Cu will be around 13,8 teraflop, 56 Cu will be 12 teraflo etc etc until 32 CU. All Navi price will be around 430 USD to 130 USD. 

As in fact I am agree with your post "12 teraflop" but i am slightly more optimist that PS5 will be around 13 teraflop (60 CU) from 64 CU disable.  

PS4 pro die is about 325 mm^2  APU size while for the GPU 235 mm^2.   It hit the jackpot , I believe it will be more than 48 CU, 56 CU  (12 teraflop ) is possible. 

From your source https://www.pcgamer.com/amd-navi-specs-release-date-price-and-everything-we-know/ : "  If Navi does end up competing with the RTX 2080, I expect the price will start closer to $450-$500—but without ray tracing support or Tensor cores. " also the same source  "Navi 20 (a variant of which is likely to find its way into the PlayStation 5) will be where AMD adds ray tracing hardware, and it will replace the current Vega and Radeon VII cards, but it likely won't be available until 2020. "

And PS5 APU will be ready in Q3 2020 https://www.digitimes.com/news/a20190416PD205.html

It's actually also aligned with my previous source https://youtu.be/7mJCOSXe_zc?t=781 which is Navi 20 that cost 430 USD.

So yeah 12 to 13 Teraflop is my opinion based on these leak and analysis.
