The Apple iPhone 6 might be Apple's first 2GHz iOS device

Apple has been known for producing anaesthetically pleasing smartphones which have an easy and intuitive user interface.....but, they disappoint the geeky people like me. Lets take the iPhone 5s. It uses a dual core cpu in a day of quad and even octa core cpus. The screen is a mere 4" diagonal when all flagships have a 5" screen. And taking about screens, the screens of those smartphones have a resolution that is twice or even four times the screen resolution of the iPhone. There are many more like the camera being just a 8MP shotter and more but with this latest leak about the iPhone 6 & more specifically the Apple A8 SoC, we think Apple has finally heard our prayers.

Leaks say that the chipset (Apple a8) is said to be made using a 20nm process, and it will still be 64-bit, as is the A7 in the iPhone 5S. The new SoC will stick with a dual-core CPU like its predecessors, though we will apparently see Apple breaking the 2 GHz barrier. This would be a first for the company's phones.

However, it's still unclear just how much the A8's CPU will go past that threshold, if at all. So it could get 2 GHz as its maximum frequency, or more than that.
This should obviously result in a performance boost for the new handset, since the iPhone 5S has a CPU clocked at 1.3 GHz.

TSMC may be involved in the production of the A8 chipset, probably alongside Samsung (Apple's traditional supplier).
