At the moment the iPad tablet, iPhone 4 and iPod Touch 4G run on an A4 chip which is a combination of the ARM Cortex-A8 processor plus a GPU chip. Apple took over the ARM Cortex-A8 processor, rebranded it and implemented it in its iDevices, giving it the name Apple A4. it assume that for the iPhone 5 terminal, Apple could use a chipset based on a baseband chip manufactured by Quallcom and a processor produced on the basis of some chips manufactured by Kinsus IC. On the other hand, Apple could combine two A4 processors, the final result being a dual-core A8 processor with twice the processing power of the current version.
The iPad tablet benefits from the full potential of the Apple A4 chipset, but the iPhone 4 and iPod Touch 4G do not, because Apple has not specified the processor frequency for these devices and it is assumed that it would be somewhere around 800Mhz.
Many of the future smartphones will have dual-core processors and Apple must implement these technologies in iDevices to keep them at a competitive level. It is true that software optimizations matter a lot, but things must also be seen from the perspective of buyers who would prefer to buy a dual-core smartphone over a single-core one. However, let's not forget that Apple has one of the best PR departments in the world that would succeed in convincing customers to buy almost any product.
