The new chips are expected to be under the bonnet of the new iPhones and iPads which are expected this Autumn.
The A8 chip is being made by a joint venture of Samsung and TSMC and word on the street is that the new A8 chip is capable of clock speeds of up to 2.0 GHz or more because its chip is fabricated using 20nm technology.
The 20nm technology means the chip consumes less power in comparison to the current generation A7-powered that are clocked at 1.7 GHz and adopt 28nm chip tech.
This entire change means that the A8’s 20nm chip gives power savings and goes like the clappers. Otherwise, the A8 follows the 64-bit dual-core processor architecture of the A7 chip.
Apple’s design seems to be based on packing more transistors into its 64-bit dual-core architecture instead of just increasing the number of cores. This is against the philosophy of other designers who want smoother multitasking. It appears that Apple wants more marketable clock speeds.
