Quanto alla domanda sul perché Ps5 e nXsX siano incomparabili per un "banale" 30% di differenza di prestazioni mentre lo sarebbero Ps5 e nXsS distanti almeno il 50% (parliamo in ambito GPU) la risposta sta, oltre che nei precedenti (Ps4 vs Xbox One series S, Ps4 Pro vs Xbox One series X) proprio nel posizionamento di mercato di Ps5 (dettato non da progettualità bensì da meri criteri di contenimento dei costi).

Gamimgbolt: PS5 Pro Possibly Hinted at in New PatentUnlike the PS4 and Xbox One, both of which were running on arguably outdated hardware even when they launched (

???), the PS5 and Xbox Series X are looking like impressive pieces of machinery, both in different ways. The need for enhanced consoles for both of them doesn’t seem as pressing as it did for their predecessors, but nonetheless, there have been plenty of questions about whether that’s something Sony and Microsoft are working on.
If a newly published patent by Sony is anything to go by, it seems they’re at least thinking about it. The patent talks about a “multi-GPU simulation environment”. While the patent itself seems to be focused on cloud streaming – which is likely referring to PlayStation Now – it does make mention of a scalable design that could be tailored for working with what’s described as a “high-end” device.
One paragraph of the patent in particular clearly mentions hypothetical “light” and “high-end” versions of a console It reads, “SoC technology can be applied to video simulation consoles such as game consoles, and in particular a single SoC may be provided for a “light” version of the console while plural SoCs may be used to provide a “high-end” version of the console with greater processing and storage capability than the “light” version. The “high end” system can also contain more memory such as random-access memory (RAM) and other features and may also be used for a cloud-optimized version using the same game console chip with more performance.”
