The reviews are there, and there are more and more coming, but PC World has tried to make the same comparison that Microsoft talked about in the launch event.
Of course comparing one machine to another is a little bit unfair, but every comparison is that. The MacBook Pro (13 inch, Core i5-5752U) is slightly faster than the Surface Book (Intel Core i5 -6300U ) on CPU-related tests, but 1) that’s a comparison between a 28W and 14W TDP chips and 2) these are chips from different generations.
And then there’s the comparison between an integrated GPU (Intel HD 6100 on the MacBook) and a discrete GPU (supposedly, a special version of a GTX 940M on the Surface Book). And the result is pretty clear. Which confirms again that the comparison is unfair. In any case:
The Surface Book’s premium price is what a premium is about. You can’t get discrete graphics in any MacBook Pro, but you can on the Surface Book. And the payoff is clear.
True.
Update (10/23/2015): another comparison, not that realistic either. I can’t understand how a tech reviewer can’t understand the difference between processors. Comparing machines by their price can really give us some surprises. Processors on both machines are absolutely different, (dual core Core i7-6600U with a 15W TDP on the SB vs a quad-core Core i7-4870HQ with a 47W TDP). Of course the MacBook crushes the Surface Book. C’mon.
