  PS2 has a custom MIPS-based RISC CPU

  PS3 is PowerPC

  PS4/PS5 are x86_64

    PS3 is not really PowerPC. The cell processor has a PowerPC core, but its a different enough custom processor that it needs its own custom coding and tooling to use it to its fullest.

        I think it was mostly because IBM would contract make chips for them using their own designs.
