Your statement are complicating each other, how can you determine the spec edging each other if you even cannot compare apples and orange LOL. You gotta choose between "you can compare " or " cannot compare ". Even on paper it cannot and it need further test and benchmark. Also even if there is a different only 15% less, and i believe all game studio want to bring their games on the same quality across the platform. They will sacrifices 15% different to bring parity for both.
Oops I misspoke. “Apples to apples”. I’m just gonna say that it’s only 15% when PS5 is overclocked. When it’s not it becomes 25%. You can’t expect it to be chugging along non stop unless you ok with it sounding like a jet engine. Just a theory.
But yes I do agree that multiplats will be largely on par. Mayyybe a slight resolution difference.
