Apple’s fondness for anorexic handhelds knows no bounds, and if this alleged deal with the Asian foundry holds water, expect to see its waistband tighten further. Rumoured back before the iPad 2 launch, the house-that-Steve-built’s reportedly been eyeing Taiwanese Semiconductor Manufacturing Corp to produce an ‘A6′ for its upcoming iPhone refresh. While it’s easy to dismiss this purported move as a direct diss to Samsung, what’s more likely is that Cupertino’s engaging in a competitive bit of size does matter — specifically, the A5′s 45nm process. A transition to newer, lower power 28nm ARM chips would give Jonathan Ives’ employer a distinct market advantage, dwarfing even TSMC’s current 40nm in the process. While it’s all still just speculation for now, only time and an iPhone 5tear-down will tell for sure.
