Qualcomm currently supplies the wireless LTE chips found in Apple's product lineup, including the flagship iPhone 5s. That partnership is not expected to change with this year's iPhone models, but analyst Timothy Acuri of Cowen and Company has heard that talks are heating up between Intel and Apple for the 2015 iPhone.
In a note to investors on Monday, a copy of which was provided to AppleInsider, Acuri said that Apple has apparently "re-embraced" Intel, and the two parties are having talks about components for next-generation iPhone models.
Acuri believes that Apple's talks may simply be a way for the company to get better prices from current supplier Qualcomm. Though the talks have apparently been ongoing, Acuri believes that Apple is unlikely to ultimately choose Intel, though he said the discussions do add an air of "credibility" to Intel's LTE baseband efforts.
The analyst made no mention of an April rumor out of the Far East that suggested Apple could bring its baseband chip design in-house.
One area where Acuri does believe Apple could make a switch is the Wi-Fi/Bluetooth combo chip found in the iPhone, which is currently supplied by Broadcom. Acuri said on Monday that he's seen evidence that Qualcomm has made "significant strides in his roadmap," which he believes could put it in a position to displace Broadcom in the next two years.
As for Intel, it purchased Infineon's wireless solutions business for $1.4 billion in 2010, which temporarily made the company a chipmaker for Apple's iPhone. Apple famously builds its own custom ARM-based central processors for the iPhone and iPad, and eschewed Intel in designing the first iPhone.
The last Apple handset to feature an Intel Infineon baseband chip was the GSM iPhone 4, which launched in June of 2010. The CDMA iPhone 4 which debuted in early 2011 used a Qualcomm baseband chip, and Qualcomm completely replaced Intel starting with Apple's iPhone 4S in October of 2011.
