It's funny how you say "no winner declared" yet the bars clearly show that the i7 out perfroms the M. The only real benefit of the M is lower power consumption and lower heat so that laptops can go fanless etc.
Matthew (11:43 PM, March 15, 2015)
Not sure that the Power consumption comparison is presented accurately? The graph implies that the Core M gets a higher score for "How much power does the processor require?" - meaning (I assume) it requires less power (as borne out in the detail comparison (3.3 times less power). What the graph confusing indicates is that the Core M gets a higher score for *using* more power. Perhaps the category needs a explanation (A higher score means less power consumption) or the like to make it clearer. Thanks!
