User-sided overclocking aside (there're AmigaOnes with 1.25 GHz 7455A/B overclocked to 1.4 GHz and Pegasos II G4 with 1.0 GHz 7447 overclocked to 1.267 GHz), some AmigaOne owners have machines with genuine 1.267 GHz 7457:

And there are even AmigaOne owners with 1.267 GHz 7457 overclocked to 1.533 GHz:
