iPhone 5 rumour rollup for the week - Macworld Australia

AnandTech’s Anand Lal Shimpi seems to have been the only one to notice that after the new iPad was announced this year, Apple has already quietly introduced a 32-nm dual-core chip. Some of these repriced iPad 2 tablets now being sold (and the third-generation Apple TV) are using a 32-nm Samsung version of the A5 chip instead of the customary 45-nm, with the same transistor technology Samsung is using in the Exynos 4.

That change, Lal Shimpi says, gives Apple several benefits: Apple reduces its system-on-chip costs and maintains its margins; dramatically reduces the overall surface size of the package; increases transistor density; and tests out a new process technology on a relatively low-volume existing product.
