The new chipset is definitely not out of the blue because if we consider a logical sequence iPhone 5 is ready to receive an upgrade and rumors have already started circulating the web regarding this. Some even speculate that chances of Apple launched a completely new iPhone 6, but analysts are of the opinion that iPhone 6 will launch sometime in 2014 and 2013 will witness the launch of iPhone 5S.
The new Apple A7 chipset, according to isodoc, will have double the number of CPU cores and RAM – meaning that the next-gen iPhone will feature a quad-core 1.2 GHz A7 CPU and at least 2 GB of RAM. A new GPU is also expected to tag along in the new iPhone – a quad core Power VR SGX554M4.
Another interesting question is if Apple will continue to use the Cortex A9 CPU cores or they will opt for something more sophisticated, like the A15 Tegra or, let’s say, Exynos 5 Octa? Time will tell.
