I've always liked to think of the SM83 as an 8080 clone that happens to use z80 assembly syntax (and includes a few z80 instructions) But it's not really accurate to call it a clone of anything. It seems to be more of a unique CPU design that happened to steal opcode and semantics from both the 8080 and z80.
