Sony Confirms PS5 Backwards Compatibility Will Support Over 4000 PS4 Games

In Sony’s very technical specs presentation on the PS5, lead architect Mark Cerny confirmed again about PS5’s backwards compatibility. The PS5’s CPU (based on AMD’s Zen 2) has been customised with PS4-specific instructions to ensure backwards compatibility at a more reasonable price. The PS3’s back-compat solution was to put in a PS2 chip inside it, which was expensive and phased out in later PS3 revisions.

While the presentation mentioned that the top 100 PS4 games will be ready for PS5 on launch, Sony has later clarified that’s not the only games that will be back-compat. On the Playstation Blog, it has been clarified that “the overwhelming majority of the 4,000+ PS4 titles will be playable on PS5.”

Sony will continue to test these PS4 games on PS5. The PS5 will run these games at boosted frequency. This should see performance increases on paper, but some games may be hard-coded to run on PS4 so testing, and additional work, may be required to ensure the games are properly back-compat.

Still, some back-compat is better than no back-compat at all. The PS5 will also have 3D audio (with its dedicated chip for it), and a custom SSD of 825GB size. The PS5 is slated to arrive by the end of this year.
