I think the comparison is still quite dangerous: possibly unfair, probably telling little about current hardware.<p>The power efficiency and core count has increased tremendously on Intel CPUs with Sandy Bridge first and late with Haswell. For the same TDP you easily get 8-12 HSW cores these days.<p>ARM CPUs have likely improved to a similar extent, but given that CPUs are getting &quot;wider&quot; and more sophisticated in terms of caches, power efficiency, etc. it is very hard to extrapolate from assessments made based on hardware that uses &gt;5y old technology.
