Why Sony should also use a Cell Processor for PS5 (x86+Cell coprocessor)

Why? All my older PC games work without adding some pentium cores and some core2 cores to my i5 CPU. And I'm sure they will still work on my next CPU (probably Ryzen).

Why? It's the same architecture. Zen cores do everything exactly the same as Jaguar cores, only 10 times faster. Backwards compatibility issues were only ever a problem on console because they kept reinventing the wheel instead of sticking to a standard. Now that they finally adapted a standard they won't move away from it and BC is basically guaranteed with all new consoles.

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.

That doesn’t make any sense. As others have already stated the Jaguar is redundant since the Zen cores already support the X86 instruction set.
