The second references Matt Mariska's misleading tweet: "Geekbench has the iPhone 7 beating the $6,500 12-core Mac Pro in single-thread." - Never mind that it's a $6,500 12-core Mac from over four years ago. This one gets regurgitated over and over.

The third still illustrates performance edging close to the Core M series of processors.

(I can't back that up, except to note that Apple fans are usually fairly scrupulous about referring to their MacBook Pro, iPad Air, iPhone 6S etc specifically rather than lumping them together).

In any case the current MacBook is quite similar to the MacBook Air and the rest of your comment probably stands.

I could be wrong, but I imagine he still knows a thing or two about CPU architecture and performance.
