We have heard that Apple has been testing prototypes of their MacBooks powered by ARM processors, but it seemed that it’s not as simple as we think. According to the ever-present “source with knowledge of the matter,” Taiwanese chipmaker, TSMC is gearing up to supply Apple with its next generation mobile processors.

Wait what? But we thought it’s supposed to be ARM? This round of speculation also comes just one year after TSMC began construction on its new $9.3 billion foundry, and teamed up with ARM — the brains behind Apple’s A5 processor.

Well, according to the apparently credible anonymous source, TSMC has already begun trial manufacturing on the chips and “has got all the authorization and details ready.” As you may already know, Apple’s current supplier of its A5 CPU is Samsung, and relations between the two have been rocky (at least in court). Of course all parties have declined to comment, which lands this report squarely in the grapevine for now.
