I am not a hardware engineer, but my guess is that making a high performing single digit Watt processor may Take different skills than doing the same thing than a 15-28-45-90-135-160W (or more) sustained TDP CPU. My only point is that assuming Apple makes the best low power CPUs should not necessarily imply they can make good high power CPUs. They may have to build up the competency over time just as they did in the initial iterations of the A series.
