The rumored portable PlayStation 6 will be able to run PlayStation 5 games without developer intervention, although a patch may still be needed for performance.
On the NeoGAF forums, known leaker KeplerL2 revealed today that, as far as they know, the portable system has shader binary compatibility, so it should be able to run previous-generation games without developer intervention. However, performance may not be great if games are left unpatched.
A portable edition of the PlayStation 6 is said to be in the works alongside the standard home variant. While the systems have yet to be officially announced, we already know they will be powered by AMD, like their two immediate predecessors, although Intel reportedly bid to produce the system. According to some recent rumors, the portable edition of the next-generation system by Sony will not be able to match the current generation base PlayStation 5, but will be more powerful than the Xbox Series S, and its SoC, which will feature less than 40 CUs, has been designed to run at very low voltages.
The regular edition of the PlayStation 6, on the other hand, hasn't been the subject of too many rumors, but Sony is reportedly planning to make it the most powerful system of its console generation, expanding ray tracing and machine learning to offer advanced and innovative gameplay features.
