Lukasz' current rule gives a big advantage to i7 (low core count, 2 threads per core, high clock rate, all the opposite for Opteron systems). In my experience performance per thread per GHz for a fully loaded system is quite similar for a wide range of processor types (I tested this for Opteron, i7 and an older core2).
