Exactly the case, and it really undermines the whole article. The general floating point performance (non GPU) is entirely irrelevant for the general uses of this device. Other subsystems might be faulty, or it could be a faulty device, but it certainly isn't floating point performance.
One line in the article that gave me a chuckle was We can say that Android Wear looks much better on a round screen. The OS was clearly designed with circular displays in mind—every button is round, producing a cool circle-within-a-circle look on the 360. Contrast this with the Verge who said that Android Wear was designed and looks better on a square screen, and is forced onto a round screen.
