A4 Processor

A4 Processor, designed by Apple Inc. on 27th January 2010 is billed as 'the most advanced chip' from all the chips apple has worked on yet. It is a type processor known as system-on-a-chip, which is the first in-house designed system-on-a-chip that includes the combination of CPU and GPU onto a single processing chip. It is the combination of the general processing power of the ARM Cortex-A9 CPU and the graphical processing power of PowerVR GPU.

The processor for Apple was manufactured by Samsung. Now the question arises, why it has been considered as the most advanced chip? The answer is due to its speed. Not only the speed is fast but also it's prudent with power. According to Apple's iPad Web Page, "The A4 chip is so power-efficient that it helps iPad get up to 10 hours of battery life." Followed by the iPhone 4 smartphone, iPod Touch that came in 4th generation and the Apple TV that came in 2nd generation, the chip has been released of Apple's iPad tablet.

The Apple A4 processor has outdated the Apple A5 processor that was used in iPad 2 released previously which was again replaced by the Apple A5X processor on the iPad came in 3rd generation. The software updates of all those devices using this chip are stopped in 2014 after the iOS 8 got released.

A4 Processor has been used in the original iPad, iPhone4 and the iPod Touch of the 4th generation. The speed of A4 was increased to 1GHz at the time of release, which provides excellent speed and power for every mobile device at that time.
