The usual Intel-ARM potshots continued at CES this year with ARM’s CEO, Warren East, responding to Intel’s new Medfield chip running on smartphones. East conceded that Intel would get a few design wins but added, “Are they ever going to be the leaders in power efficiency? No, of course not.” In many ways, East was less concerned with Intel and much more focused on Microsoft. Microsoft will release its Windows 8 with ARM support soon, and East is eager to get ARM chips onto tablets and laptops running the Windows operating system. He’s also guarding against any possible Microsoft turnaround in mobile meaning Intel might have an opening in smartphones. More broadly, as more code moves to ARM architecture, the difficulty of putting ARM chips in data centers gets chipped away.
