Apple delivered a performance breakthrough Wednesday with its new A5X processor for the iPad,but it's possible that this chip won't make its way into the next iPhone, analysts said.
The chips used in the first two iPads, the A4 and A5, both made their way into a new iPhone soon after. But the A5X, with its heavy focus on graphics, may not be ideal for smartphone use, and Apple may wait for a more power-efficient chip built with a new manufacturing process.
