Did I forget to mention the R800 is a RISC processor?  |

No, the R800 is a CISC processor.
RISC involves two things: implementation and, more important, architecture. The Z80 (and thus the R800) architecture has nothing to do with RISC...
There.
This could become an 'I'm last!'-thread |

I guess I forgot to mention the R800 is a RISC processor... Stupid me! |

Naah, it's not. Every smart person knows that R800 is CISC. |

I hope this will quiet things down.  At least for a short time.

I guess that probably leaves you out then?
Come on guys, please stop this fight whether or not the R800 is a RISC or CISC processor. I know no other processor doing things 8 times as fast with just 2 times the operation frequency. |

Well, then just leave it like this: the R800 is a good processor. No-one will decline that |

Z80A is better, it's the real deal!

The real deal of what? It all started with the 8080 anyway! |

Little brother in what name? In name?
There is no connection whatsoever between the MIPS architecture (of which R8000 is one implementation) and the R800 (Z80 descendant).
If the R800 is code-compatible with the Z80, how in the world could it be the little brother of ten years younger RISC architecture, or of a processor which was released several years later? That would imply that the R8000 designers would all of a sudden have taken inspiration from a several years older Z80 clone, instead of the R8000's predecessors (R3000, R4000, etc) or from contemporary RISC designs.
Don't make me laugh. |

Actually, most modern RISC processors can swap endians. |
