  1. At this point, and since they obviously will wait for 7nm fabrication. Having only 10TF is a joke and almost impossible. Look at it this way. Going from 28nm to ~14nm fabrication resulted in going from 1.2TF GPU to 6TF GPU. And you think going from 14nm to 7nm will not even double that 6TF but end up at 10TF? How? Why?

 

You should compare original ps4 to ps4 pro. You see a 1,8 TF jump to 4,2 TF, overall 2,3x increase. And this gave a higher power consumption when comparing the two consoles. Expect something similiar with Ps5 if they launch 2019-2020 with 7nm transistor technology. About 9 TF is my guess.

If they go for a higher TF number, they either has to increase the chip size or go with higher clock speed. Which just lead to higher cost for a bigger chip and more expensive cooling.

Of course I would like more TFlops, but let´s be practical here. With a balanced memory hierarchy and 9 Teraflops, The PS5 would be just like the PS4 in full HD. I mean, most games (not all) run 30 fps 1080p with 1.84 Teraflops on PS4 with a crappy CPU. 

1,84 x 4 = 7,36 Teraflops. So an 8 teraflops machine would be able to run in 4k 30 fps in most games if data feeds the gpu acordingly. Now, If you tell me, I would like at least 30 % more perf than that for anti aliasing and better dinamic resolution if games run at 60 fps. That´s a little more than 10 teraflops. Would that feel like a new console generation?. No, but it will look nicer than a 1080p standar PS4 for sure.
