PS5 and Xbox Series X will be "almost" backward compatible with PS4 and Xbox One

PS5 and Xbox Series X will be backward compatible with PS4 and Xbox One

PS5 and Xbox Series X both consoles will be backward compatible with PS4 and Xbox One games. Sony and Microsoft had openly confirmed it, although according to Yves Guillemot, CEO of Ubisoft, it will not be total backward compatibility.

During an event held with shareholders, Yves Guillemot has said verbatim that PS5 and Xbox Series X will work with almost the entire PS4 and Xbox One catalogue and explained that this will be something new for the industry that will facilitate the transition between the current generation and the new generation. That “almost” is undoubtedly the most interesting of this information, and leaves us an important question, why “almost all” and not all?

I think this issue may be limited to an exclusive and licensing issue, that is, some publishers may not want to accept that backward compatibility because they are going to release improved versions for PS5 and Xbox Series X, and they don’t want to “lose money” accepting that Unimproved versions of PS4 and Xbox One can work on both consoles.

It is a simple argument but it is full of meaning, after all: would you buy a game that you have finished on PS4 to play on PS5 with a small improvement in graphic quality? Already, calm down, I have heard the non-majority without a problem.

How will backward compatibility work on PS5 and Xbox Series X?

That is the great unknown we have right now on the table, and the truth is that it is not at all clear. In principle both generations have a common base: CPU x86, AMD Radeon GPU and unified memory, so introducing that backward compatibility should not be at all complicated, or at least not as much as what Microsoft had to face with Xbox One and Xbox 360

The AMD itself explained, in fact, that it decided to maintain the base of the GCN architecture, present on PS4 and Xbox One, in the first generation RDNA architecture so as not to give up all the optimization and the technological base in general that they had settled around that. This helps us understand why both Sony and Microsoft have chosen to use graphics cores based on the RDNA 1.5 architecture on PS5 and Xbox Series X.

For hardware issue, there is no complication, and for software issue, I think not, since the base of PS5 and Xbox Series X will be almost a copy of the current generation. With this in mind, I think that backward compatibility could be executed through two very simple and beneficial ways for the user: directly through the original disks or, in the case of the contents acquired in digital format, by linking the account in which we have associated.
