I agree, the language is ambiguous as to what defines a "chip", but I assume given the context of the sentence and the technology that it is meant to be read as: the only manual layout of an ARM core to hit the market in several years. Even then "several years" is unspecific, and could mean practically anything from the iPhone classic release era (which is basically ancient history by smartphone technology years at this point) to the (not that old) iPhone 4 release era.
