Apple (AAPL) is reportedly hard at work finding ways to finally dump Samsung once and for all as the companies’ rivalry continues to escalate. According to a new report from the Far East, it looks like the first in a series of moves away from Samsung (005930) components is now being made. Digitimes on Thursday reported that TSMC is expected to “tape out” Apple’s upcoming A7 chipset this month using a 20nm process. Risk production will reportedly follow in May or June, and the chipset is expected to appear in commercial products starting next year.
