Illustrations in Sony patent documents about emulation of old console games on new consoles. (Sony Entertainment) The PS5 is predicted to use a processor (CPU) and GPU with the latest architecture that is faster from the oldest.

However, this architecture is not necessarily the same as the previous generation of consoles. The PS3, for example, has a Cell Processor with a unique architecture that is difficult to emulate so Sony has trouble making PS3 game emulators on the PS4 The existence of this latest patent indicates that Sony might have found a way to emulate PS3 games on the PS5, along with PS4, PS2 and PS1.

However, the patent does not mean the old game emulation technology will really be present in the next generation Sony game consoles. Even if applied, it might not be on the PS4, but another variant of the PS4. For now, PS2 emulators are already available to PS4 owners through the PlayStation Store. Then, some PS2 and PS3 games are offered to the PS4 through the PlayStation Now streaming service.
