I don't have enough hardware knowledge to dispute that, but I have a feeling that's not that easy to gain massive performance boost. If I recall correctly, the biggest Apple's ARM CPU advantage has to do with fixed instruction length whereas x86 is variable. Fixed one gives you an prediction advantage because you exactly know how many instructions are in cache and where are they located - something along this. But let's hope for the better.
