It's worth bearing in mind the phenomenal level of expertise that Apple have in ARM SoC design. The A12x is in many respects competitive with u-series i7 processors, despite a significantly lower TDP. The A12 Bionic has a vast performance advantage over any other mobile SoC. We don't know what they could do with a much bigger die and a much bigger power budget, but my expectations are high.
It's pure speculation on my part, but I wouldn't be hugely surprised if the first ARM-based MacBook could match the performance of the previous Intel-based machines when running emulated x86 code and substantially outperform them when running native code.

To me, this would be highly surprising - in particular if we are talking about x86 code that uses AVX instructions. If you want evidence, just consider the performance difficulties that x86(-64) emulators for game consoles that do not use x86 processors such as PS3 or XBox 360 have.
