It matches pretty much what insiders like Matt from Era said the power gap is closer than its ever been, so the difference might not be perceptible.I take advantage of your reply to present something general.
Try (everyone) to read the following text objectively.
In times of load and "fineness in visual detail" (not resolution) the thing is in favor of PS5. I don't think it will change if things are done the way they have to.
Now, perceptibly for the user there might be no difference, which is what really matters. Demon's Souls Remake could look just as "good" in XSX without any problems. Surely with "longer" load times (few seconds), without the DualSense touch experience or immersive 3D sound (another type of sound, good too), but visually "identical" in one way or another (we could even debate about if in XSX higher refresh rates could be achieved, although for an exit title it doesn't really matter).
Likewise, all this is so relative ... it depends on the development study, it depends on the development time, the budget, if it is exclusive or not ... too many factors to be able to make a real comparison.
Also keep in mind that no "totally nextgen" gameplay has actually been seen (by any of them). And both can do much better things. The problem with MS is the lack of games that take advantage of its system and, if I am not mistaken, that absence will last for 1 more year. But once we start to see XSX games that really take advantage of the system, we can really be sure if more power is better or more efficiency is better. In practice we are talking about very similar percentage margins.
I think that we will have to wait and see what Ninja Theory achieves in XSX and Naughty Dog in PS5 (if possible in games with similar characteristics) to really know which is the best way (I am talking only about visual finish, regardless of the game's argument ).
As for the difference in Multiplatforms, the real difference "should" be less than that of this image.
In short, it all falls to development studies. It depends on which way they go they will obtain some results or others. Until then (2 or 3 years) it cannot really be valued. For now, in my opinion, the one that has to prove something now is XSX. And it will surely prove it (you need it).
Now what will matters is studio's talent, budget and manadgement.
I think It showed pretty good with Halo and the crossgen debacle.When MS touted their cross gen approach then showed Halo a lot of people myself include said get out with that cross gen bullshit.But Spidermand and Horizon showed that crossgen can be done good and the Halo was more a 343's problem than a crossgen one.
And if Sony manages to make some good looking cross gen games there's no reason Ms cannot do it too.Especially considering how close they are in power...Even with the I/O because honestly if a ps5 can load something in 1 sec and XsX in about 2 sec is it really that different for the consumer?
