Are you referring to the i7-6700HQ that was released in 2015? The CPU that's present in the 15" Retina MacBook Pro? Or is there a different CPU that nobody else is privy to?
There isn't a mobile class edition of the Kalby Lake processor with four cores available. The 15" Pro has been quad core as long as I can remember. It was also only announced a few months ago.
Skylake processors were announced last year and the new laptop uses them. In fact, I believe the 15" BTO edition uses the fastest Skylake processor Intel makes.
