During today’s PlayStation 5 livestream, Sony announced that the PlayStation 5 will be backwards compatible with PS4 and PS4 Pro games, but the company made no mention of retro PS1, PS2, and PS3 titles. From a report: Mark Cerny, Sony’s lead system architect for PlayStation hardware, said the following about the PS5’s backwards compatibility: “The PlayStation 5 GPU is backwards compatible with PlayStation 4. What does that mean? One way you can achieve backwards compatibility is to put the previous console’s chips at in the new consoles like we did with some PlayStation 3s, but that’s of course extremely expensive. A better way is to incorporate any differences in the previous console’s logic into the new console’s custom chips, meaning that even as the technology evolves, the logic and feature set that PlayStation 4 and PlayStation 4 Pro titles rely on is still available in backwards compatibility modes. One advantage of this strategy is that once backwards compatibility is in the console, it’s in, and it’s not as if a cost-down will remove backwards compatibility like it did on PlayStation 3. Achieving this unification of functionality took years of efforts by AMD, as any roadmap advancement creates a potential divergence in logic.”
