Posted it in another thread, we jumped 8.7TF in 3 1/2 years, not that it means shit but it gives and idea and yes bla bla technology is slowing down and yes bla bla you can't compare high-end desktop GPU's with consoles.
Shouldn't be hard for GPU's in 2020 to be above 20TF, 4-6TF less in a console seems fair.
I think performance per watt should be a much better measure. The latest Vega, for instance, is said to be quite power-hungry.
