The involvement of GlobalFoundries
in production of Apple's A-series chips likely has the company serving as "flex capacity" for Samsung, new sources affirm. Under that arrangement, Samsung is expected
to pay for use of GlobalFoundries' Malta plant to boost A-series production when the Samsung facility in Austin, Texas is under strain. Although the Austin factory is dedicated mostly to Apple chips, it also helps produce chips for Samsung's own devices; there are, therefore, times when a second plant might be needed to satisfy dual demands.
There has been some speculation that GlobalFoundries could serve as a second source of A-series chips, independent of Samsung. As a rule Apple has been trying to distance itself from Samsung, with which it's entangled in a number of patent lawsuits. Several reports have hinted that TSMC could take over some or all of Samsung's A-series production, but to date a rumored transition has yet to even begin.
