The additional issue that is not addressed in the article is the fact that Intel has a mix of performance and economy cores.
And the hidden secret is that on some workloads, the wrong core is selected, meaning that you get subpar and rubbish performance (even when the performance cores are snoozing around, doing nothing).
So, yes, Intel does have on those two specific CPUs some multi-thread advantage, but only if the correct cores are selected (which doesn't happen 100% of the time).
Also in terms of performance, you also need to measure latency. What is the point of having a fast memory interface, if the cache chokes and needs to constantly being updated from the slower memory? At that point, having a slightly faster memory does help, but again, depends on the workloads (and the comparison is using also productivity multi-threading, so not 100% game oriented this comparison).
Also I would like to see the comparison per watt used, and not just a raw performance.
