The Z80 (designed by Federico Faggin and Masatoshi Shima - two of the 8080 designers) was designed to be binary compatible with the 8080 but more capable - so the architectures would have atleast started out very close.
> The Z80 CPU can execute 158 different instruction types including all 78 of the 8080A CPU
