for the compiler suite, the 32-bit powerpcs are compatible
(ignoring the original 601 and not including Altivec)

kernels see bigger differences, where there are three or
more possibilities for memory management, and two different
schemes for trap handling, and even different instructions
for processor control, but generally the differences are
fairly small.   the surrounding IO structure is usually completely
different.

64-bit operation is a fairly small extension to the
32-bit set, as for several other RISCS, compared (say) to x86
