Nikkei Asian Review, first on Apple rolling their own modem chip:

Two other chip industry executives also echoed Li’s view that Apple will develop its own modem chips or at least boost its related capabilities – a view bolstered by Apple’s poaching top Qualcomm modem chip engineer Esin Terzioglu earlier this year.

But Li added it is was unlikely that Apple could quickly roll out such components within two years. Modem chips have a very high threshold to develop and need to fulfill requirements of different operators worldwide.

A veteran chip industry executive estimates that it would require more than a minimum one thousand engineers to work on such a project.

As far as Macs go:

Core processor chips for the MacBook range is another area Apple is trying to venture into.

Two industry sources say that Apple is trying to cut its dependence on Intel when it comes to notebook chips and instead build those using ARM architecture, referring to the SoftBank-controlled British chip designer.

“Notebooks are becoming thinner, while consumers are demanding better mobility and longer battery life. That gives ARM’s architecture, which is known for its power efficiency, a very good opportunity,” a chip industry executive said.

And:

Apple also aims to design its own chips that could integrate touch, fingerprint and display driver functions, sources say.

“Apple has hired engineers from Taiwan’s No. 1 display-driver chip designers Novatek and panel makers of AU Optronics as it wants to control next-generation display technology and some related key components,” said a Taiwanese chip industry manager.

Apple switching Macs to ARM chips has long been a topic of speculation. And there are significant technical hurdles to overcome. Interesting, but take with a grain of salt.
