| Trumpstyle said: My guess is that console games for ps4 are specifically designed to work with 6 jaguar cores. But this what Mark cerny said about this subject when talking about ps4 pro: But surely x86 is a great leveller? Surely upgrading the CPU shouldn't make a difference - after all, it doesn't on PC. It simply makes things better, right? Sony doesn't agree in terms of a fixed platform console. "Moving to a different CPU - even if it's possible to avoid impact to console cost and form factor - runs the very high risk of many existing titles not working properly," Cerny explains. "The origin of these problems is that code running on the new CPU runs code at very different timing from the old one, and that can expose bugs in the game that were never encountered before."
To me this is clear. Using ryzen cpu will break backwards compatibility. That's why I'm guessing ps5 will have 4 ryzen cpu cores + 8 jaguar cores if they go for BC. |
This says nothing without deeper knowledge of how the majority of games for the console are programmed. It might be solvable with a simple patch and if it's connected to clock speeds it should be easy to have older games run in a legacy mode where the PS5 just locks it at lower speeds.
The tools that are used to program for PS4 should be old and standardized enough to make any software issue solvable without resorting to legacy hardware. I don't really think it's possible to program a game so statically that a newer processor can actually break it. Especially considering that the vast majority of games runs on multiple platforms and as such shouldn't be hardcoded to specific hardware platforms.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
