More proof that Apple is building an ARM SoC for Macs

"Patrick Moorhead, a former AMD executive who now leads the research firm Moor Insights & Strategy, said Mergard brings deep expertise in both PC technology as well as in products known as SoCs–systems on a chip–that combine various kinds of special-function circuitry on a single piece of silicon.

Besides the current breed of Apple smartphones and tablets, Moorhead says Mergard’s talents could potentially be applied to Apple’s PC efforts, where its Macs use Intel chips but not SoCs. “He would be very capable of pulling together internal and external resources to do a PC processor for Apple,” Moorhead says."
