One thing is the theoretical number and another thing is the difference, in practice, between the systems. The numbers are very good for Marketing. And yes, it is true, the specifications are what they are (although I do not agree that RAM plays in favor of XsX, rather the opposite). But at the Hardware level, in practice, it is the generation that has the least difference between one and the other. And what MC did yesterday didn't seem to imply that. That was my analysis. Regarding your question, there is a lot of custom hardware that compensates for the small difference. And above all (by historical analysis) games. That's what history is about. If people want to continue buying a system for its "power" it is in its right, but in my modest opinion it is a mistake. It was in the past and it is even more so now. The system should be purchased based on the games you want to play. The difference in quality between the multis will be negligible (or should be in practice), I would even dare to say that in practice we will see more multis from XsX weighing down PS5 than vice versa.
Of course, DF will never have problems finding differences. They live on that.
On the other hand, there are things that have not been said or have not been explored (by both sides).
Regarding the gif (which surely more than one will ask me) the pact with the devil were two factors. SSD first. I think you still have no idea what an SSD that loads 2GB in 0.27s means. Not only useful for load times, but for many more things. Sony's breakthrough in VR in terms of photorealism and immersion. There are more things that I can not comment on, but basically it really depends on the developers.
