For years now, Apple nerds have pined away at the idea of Intel building ARM chips for Apple. Intel has always been at the front end of technology in terms of die shrinks and chip manufacturing. Unfortunately Intel has also always insisted on only building its own designs. That makes sense. I suspect being a chip designer/manufacturer is much more lucrative than being just a chip manufacturer.
Yesterday we received news that Intel has changed its mind and is now planning on building chips based on the ARM design. This seems like good news for Apple. It allows Apple to distance itself from Samsung (that same company that Apple sued for design theft) currently produces a lot of the chips found in iPhones and iPads. I'd also speculate that an Intel manufactured Apple ARM chip is smaller and more power efficient.
Without any inside knowledge, I’m guessing that Intel did not want to get into the chip-manufacturing-for-others business. Nonetheless, here we are. Let’s hope the iPhone and iPad can benefit.
