There are some pairings that just make sense. Fish and white wine. Chocolate chips and cookies. Intel and Apple.

Since 2005 Intel has been supplying Apple with processors for its Mac computers but, according to a report by Bloomberg, that may change soon.

An initiative known as Kalamata will see Apple turn to its own foundries to produce CPUs for Mac computers by 2020 if unnamed sources familiar with the matter are to be believed.

On the back of this news Intel share prices fell 9.2 percent, the largest intraday drop in two years according to Bloomberg.

Apple has said it doesn’t comment on speculation which doesn’t tell us too much.

The Cupertino firm dropping Intel might not be as surprising as it sounds. Chips in the iPad, iPhone, Apple Watch and even Airpods are designed by Apple with help from Arm Holdings.

Ditching Intel would allow Apple to develop its own chips for its PC brand without relying on Intel’s roadmap. That might be very valuable for Apple which is very much at the behest of Intel when it comes to updating its Macbook line.

The other reason Apple might be considering the move to its in-house hardware is homogeneity between its products. Reports suggest Apple is working on software known has Marzipan that would allow Macs to run iOS applications. A shift to similar architecture might make it easier for users to access everything from one space.

With 2020 just around the corner this will be an interesting story to watch but it’s worth keeping in mind that this is very much a matter of speculation at the moment with nothing bring confirmed by either Intel or Apple.
