Chinese Economic News Service (via MacRumors) is citing Citigroup Global Markets analyst J.T. Hsu today as claiming Apple will make the switch to TSMC’s 20nm process for quad-core processors over the next couple of years. The rumor is something we have heard several times in the past:

According to Hsu, Apple will utilize the processors in iPad, “iTV” (Apple TV?), and MacBooks, while iPhone’s will remain with duo-core chips:

In August, Bloomberg reported both Apple and Qualcomm failed to obtain exclusive chip production rights from TSMC after putting up over $1 billion in bids. Samsung also recently made big investments in its new Austin, Texas plant manufacturing chips for iPhone, iPad, and other Apple products, indicating multi-year contracts are likely in place.
