Looks like Apple is ready to jump ship from AMD. They should hire me as a consultant. http://techreport.com/discussions.x/22044
SemiAccurate says this change of heart has to do with Apple's purported decision to cancel a MacBook Air model featuring AMD's A-series APU. Reportedly, that system was "really close to production" this spring, but Apple balked because of the supply problems plaguing AMD's 32-nm products. The current, Intel-powered MacBook Air was Apple's "plan B," SemiAccurate claims.
The link between those two rumors might seem tenuous, but Apple does have a reputation for being tough with suppliers. Nvidia GPUs were unceremoniously phased out from the Mac family after Nvidia's solder bump problems, which caused chip failures in many pre-built machines, came to light.
