Developping for PowerPC vs x86 vs ARM as very little impact. 99% of the code is agnostic to the architecture. Some optimizations are more effective on one or the other, but they have most of the time a positive impacts on all of them.
In any case the biggest bottleneck is memory bandwidth and cache usage, and that has nothing to do with the cpu family, but the whole system.
