ARM at Computex

Intel used the geometric mean of the benchmark scores, which is not only the correct mean in the case if rates comparisons, it is also considerably more conservative...Silvermont may actually still have an upside surprise in store on some benchmarks.

ARM presented to my knowledge very little information about how they were measuring performance in that chart. That community often resorts to DMIPS as a measure to make their chips look as good as possible against x86, so that wouldn't surprise here. Dhrystone, though, is not particularly meaningful in this use case, especially compared to the battery of tests Intel says they subjected Silvermont to.
