It appears like Sony are already thinking, or more like setting in motion the plan for PlayStation 5 Pro, the juiced up version of the original console.
In spite of the tech advances PlayStation 5 will be bringing to the table, and there are more than meets the eye, we suppose a souped-up version is traditionally inevitable.
As caught by LordsofGaming, Sony Interactive Entertainment filed a patent called "Scalable Game Console CPU/GPU Design For Home Console and Cloud Gaming".
It talks about a System-on-a-Chip (SoC) that can be stacked and connected with high-speed buses to improve performance. It also admits that the solution is less optimal than building an actual chip, but the cost efficiency is clearly key.
"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 produce a 'high-end' version of the console with greater processing and storage capability than the light version", the patent reads.
It looks like Sony are targeting an SoC of such modular nature that it would cover everything from consoles to cloud-based gaming. We're not sure whether this means they'll go for some sort of modular architecture that Stadia supposedly has, but it sure sounds like it.
"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", the patent reads.
