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

Yeah but the PS3 launch model also had PS2 hardware inside, 2 GPS and 2 CPUS and it was possible

It was also the most expensive console of all time if I remember correctly.

You completely misunderstood what Mark Cerny is saying. He choose the Jaguar cpu for Ps4 pro because it will make all ps4 games run flawless and bugfree.

Actually I haven't.

Zen is fully backwards compatible with Jaguar from an ISA standpoint.

Actually, even the early PS2 had PSX hardware inside, and only later in it's life the extra hardware was dropped. But, this was at a time when the PSX hardware cost next to nothing, as it was still mass-produced. This situation would be different from adding Cell for BC, as it is not manufactured anywhere, making it a very expensive processor.

But the problems with PS2 BC on PS3 had nothing to do with the CPU (that could be emulated rather easilly), but actually with the GPU memory bandwidth (all BC PS3's have at least the PS2 GPU inside), that was much higher than that of PS3's. PS4 should not have problems emulating PS2, because the GPU memory bandwidth is higher than that of PS2's.

The PSX hardware was always being used though, even for PS2 games as it handled the I/O of the entire system, so the costs for it's inclusion could be justified.
That wouldn't be the case for Cell in a hypothetical future console.

I think i gonna read your post and reply to you next year, cheers

Do some research whilst you are at it.

I recall the PS2 chip cost Sony $27 to put in PS3 at the time so easy to see why they cut it.
