Former Intel engineer reveals why Apple is switching from Intel to Apple Silicon

One of the biggest news to emerge from this year’s WWDC was Apple’s switch from Intel processors to its own ARM chips or Apple Silicon for its future Mac computers. Apple has been using Intel processors for the past 15 years. Although Apple claimed the move was because of its plans to consolidate its platforms, there was definitely an underlying reason for its decision.

A former Intel engineer François Piednoël told PC Gamer that Apple has not been satisfied with Intel’s processors for years. The proverbial straw that finally broke the camel’s back was the quality control issues with Intel’s 2015 Skylake chips.

Here’s what Piednoël had to say:

“The quality assurance of Skylake was more than a problem, it was abnormally bad. We were getting way too much citing for little things inside Skylake. Basically, our buddies at Apple became the number one filer of problems in the architecture. And that went really, really bad.”

“When your customer starts finding almost as much bugs as you found yourself, you’re not leading into the right place.”

“For me this is the inflection point,” said Piednoël. “This is where the Apple guys who were always contemplating to switch, they went and looked at it and said: ‘Well, we’ve probably got to do it.’ Basically the bad quality assurance of Skylake is responsible for them to actually go away from the platform.”

Apple first used Skylake processors with the 2015 iMac and subsequently used the same chips in its 2016 MacBook and MacBook Pro models. Apple’s problems with Intel were not limited to the Skylake incident, Apple’s Mac pipeline has been affected by Intel on several occasions.

It is not a secret that Apple has always valued integrating hardware and software in its devices, controlling every aspect of the production of its products. The company has already been building its own system on chips (SoCs) for both the iPhone and iPad since 2010.

Apple has outlined a two-year transition timeline away from Intel. During that time it will still produce Intel-powered Macs. The company expects to ship the first Mac with Apple Silicon by the end of the year.

Following Apple’s explosive announcement, Intel said it would continue to support the Mac through this transition period, but it insisted that its processors were still the best option for developers.
