    Another opinion:

    "Except for Freescale, most Power licensees base their devices on CPU core designs from IBM. AppliedMicro is the exception. It developed a new CPU of its own (Titan), then halted that effort and started afresh on a new design that may arrive shortly."

    So maybe Titan wasn't based on any PPC4xx core at all? The more information I read, the more confusing it gets ;-)
