Indeed, other big.LITTLE like designs are out there besides the A11. But the article isn't strictly focused on "Apple is a superior innovator."

...and then he proceeds to devise a test. This is ultimately how you might verify the functionality of the hardware and the Darwin scheduler. If it were naive, the test might not have behaved this way.
BTW if anyone wants to do similar experimentation with a MUCH cheaper target, you can use the ODROID Xu4 (Exynos 5422, < 100 USD).
