Again. Slowly. PS4 was designed with 4GB RAM at first. And that's not what i'm saying. That's what Yoshida said. And it was confirmed by Penello, that Microsoft also thought, that Sony will go with 4GB RAM. Yup. I's possible, that Microsoft had info on first machine and didn't know what's Sony changing after that.
But of course, you haven't addressed my whole point, which was "One company have general idea, what you are doing with your console." and you are just spouting shit about "tiresome Xbox fans." So if you want to do that, by all means go for it.
Yup, it is possible, that Sony thought, they are the only company on the market, that can push RDNA to over 2GHz and by that save some cost, because of smaller chip. It is also possible, that they overclocked it after they found out what is Microsoft doing and it is also possible, that RDNA 2 solved all problems with high frequencies. Nobody know for sure. But arguing in way "surely is planned by Cerny" is most "fanboyish" thing to say. Just blindly believe everything he says because he is an architect of your favourite console
But if you are not willing to have civilised discussion and you want to just attack everybody who dares to question what Cerny is saying, then we have nothing to talk about.
