The transition to 20-nanometer processes will yield transistor cost savings of 7.5% to 8.5% compared with 28-nanometer chips, rather than the usual 30% savings seen under Moore's Law, said Subi Kengeri of GlobalFoundries. "Even without [extreme-ultraviolet lithography] we will get back to the traditional Moore's Law cost reduction curve at 10nm because of process optimizations," Kengeri added. Separately, a GlobalFoundries spokesman confirmed that Executive Vice President Mike Noonen has left the company and that Chuck Fox, senior vice president of worldwide sales, will assume some of Noonen's former duties on an interim basis.
