Amazon and Apple powering a shift away from Intel chips

For close to a decade, supporters of the chip technology that powers mobile phones vowed to shake up the market for computers. For the most part, they made little headway.

Now that finally seems to be changing, in a potential power shift over the direction of the computer industry.

The change is being driven by Apple and Amazon, two tech behemoths that are cutting their dependence on the Intel chip technology that has long controlled most personal computers and larger server systems. Instead, the companies are increasingly leaning on their own homegrown chips that were designed using technology that Arm, the British company, licenses for smartphones and other consumer products.
