All of that is totally unverifiable. There is significant doubt that it is reality and not just extremely narrow case for marketing.
With Xeons we know, there are tests. With Opterons we know because of tests. With ARM we know only some samples from Caldexa (no longer exists) and from NAS. Not really good showing as the only really advantage of ARM is cheap, but performance is missing.
Evidence is still mostly missing.
