Apple is testing an iPhone with A5X processor
According to reports on 9to5Mac, Apple is testing a prototype of a new iPhone. This prototype is mounted with a variant of A5X processor, which is already present in the new iPad and suppose that will have less power consumption to extend the autonomy of the device as possible. It makes little sense to put the A5X on an iPhone when that processor is born only to move the new iPad Retinal Display with ease.
Lastly, it’s possible that the iPhone 6 will use an upgraded version of the A5X and not the quad-core A6 chip many were expecting. Since Nvidia released it’s quad-core Tegra 3, there’s been a lot of back and forth between mobile processor makers about which is better–a quad-core chip based on older ARM Cortex-A9 processors or a dual-core chip based on the newer ARM Cortex-A15 processors. We’ll have to wait until the next generation iPhone comes out to see what Apple thinks.
As with the new iPhone, this iPhone prototype has 1GB of RAM versus the 512 MB iPhone 4/4S. This is a test model labeled under the name of N96 that has been created to see how it behaves this processor on an iPhone so it does not mean the end mass produced. In regard to the iPod Touch, it seems that Apple is also working on the fifth generation model (iPod 5.1)as shown by a build of iOS 5.1. We do not know if this new iPod Touch will inherit the current A5 or if Apple will wait to introduce this variant of A5X.
