Exactly right. ARMs lure isn't really the current performance for supercomputing, it's rather the expectation that they will hit the next big performance wall much later than x86 because of its simple architecture that's suitable for the maximum amount of cores per die space. Give it 2-3 years and we might have the big step in supercomputing architecture at hand.
