Intel's rivalry with ARM looks set to heat up with reports suggesting Apple will switch to ARM processors in its laptops from 2013.
According to the SemiAccurate website, Apple is planning to move to ARM chips as soon as possible. Sources have told the website that this is a "done deal." The reported deal could also see ARM chips make their way into Apple's desktop range as well.
Sixty-four-bit variations of processors built on ARM's architecture are due to arrive at the end of 2012 or early 2013, which fits in with the timescales suggested in the report.
The report suggests that Intel isn't yet aware of the plans. Intel did suggest that it would be interested in manufacturing A4 and A5 processors -- currently used in the iPhone and iPad ranges -- earlier this week, as Apple Insider reported. Early speculation about the iPhone suggested Apple would turn to ARM at that time.
Though the A5 chip was designed by Apple it is manufactured by Samsung, and the SemiAccurate report suggests that Apple would be looking to companies such as Samsung to manufacture the ARM-based chips for its laptop lines too.
Intel processors first appeared in Macs back in early 2006.
