GloFlo was responsible for the delays to AMD's last round of make-or-break product launches and it appears that AMD just does not want to take the risk with Zen.

A rumour states that Globalfoundries has reportedly suffered a setback recently as a result of its owner, the government of Abu Dhabi, deciding to cut back on expenses after oil prices crashed. To save cash GloFo is apparently attempting to retool its 28nm equipment for 14nm production., but this is taking too long and the yields have been stuffed up..

TSMC has undoubtedly faced its fair share of setbacks but it has successfully managed to iron out most of the kinks and its 16FF+ high performance process is set for volume production this quarter.

Nvidia is taking its Pascal GPUs to TSMC next year. AMD's next generation Arctic Islands will also be produced at TSMC.

AMD has announced that Zen will be available starting next year. The new CPU core will be fabricated using FinFET technology, however the company has not yet specified whether it will be Globalfoundries' 14nm Finfet process or TSMC's 16nm FinFET process.
