Power is Mainframe (the cores are power) too, with a OS/370 Microcode layer on top of it, with a layer of z/VM Microcode Code on top that (for LPARS etc), and then the installed z/OS or Z/VM and inside Z/VM a Z/OS, Z/VSE OR yes really another Z/VM. https://www.youtube.com/watch?v=5jOlO1vSBzE https://www.youtube.com/watch?v=5jOlO1vSBzE >we run MVS 3.8 on top of VM/370, on top of zLinux, on top of z/VM, on top of an LPAR, on a real iron IBM mainframe.

Mainframe CPUs (https://en.wikipedia.org/wiki/IBM_Telum_(microprocessor) https://en.wikipedia.org/wiki/IBM_Telum_(microprocessor) for instance) are physically different processors than Power. (Although it is likely that IBM shares the many internal design parts among both of these.)

  Yes they are NOT PowerCPU's but the core's are based on the power architecture with ++ and secret sauce.

    There's really not that much shared between Power and z cores.
