My reading of his comments so far has been, they are close in power, and Series X is stronger. But, that's only one part of the equation.
Entertain this for a moment, Series X is achieving 12.1TF through
[email protected]. If, PS5 is achieving 11.2TF through
[email protected], then how do you ascertain the differences? Yes, one has 0.9TF of more computation power, but one has faster clocks, which would achieve faster fill rate.
I feel doom and gloom spells are justified, if PS5 is actually in ~9TF territory, a ~30% compute difference is substantial, no matter how fast the clocks are. But, if they are close (which according to his latest tweets, they are, as in he is standing by RTX2080 comments) then I don't see much problem.
