Part of that was the greater clock speeds on the 601 and 603, though. Those started at 60MHz. Clock for clock 68K apps were generally poorer on PowerPC until PPC clock speeds made them competitive, and then the dynamic recompiling emulator knocked it out of the park.
Similarly, Rosetta was clock-for-clock worse than Power Macs at running Power Mac applications. The last generation G5s would routinely surpass Mac Pros of similar or even slightly greater clocks. On native apps, though, it was no contest, and by the next generation the sheer processor oomph put the problem completely away.
Rosetta 2 is notable in that it is so far Apple's only processor transition where the new architecture was unambiguously faster than the old one on the old one's own turf.
