iPhone 5 to be less powerful than its competitors?

As reported earlier today by PCR, a video has surfaced that reveals a whole bunch of components that are reportedly taken from the latest iPhone.
One of the items in particular is a logic board, which was exposed to show off more of the device's components.
The importance of this would be the presence of an A5X chip, which is commonly found within Apple's latest iPad.
Whilst this may sound impressive off the bat, the chip itself is only a dual-core offering - something that would trail behind the power of chips within the device's closest competitors such as the HTC One X, Samsung Galaxy S3 and LG Optimus 4X.
