苹果的处理器是由三星制造的。 现在出现了一个问题，为什么它被认为是最先进的芯片？ 答案是由于它的速度。 不仅速度快，而且省力。 根据Apple的iPad Web Page的说法， “ A4芯片非常节能，可以帮助iPad长达10个小时的电池寿命。” 紧随其后的是iPhone 4智能手机，第四代iPod Touch和第二代Apple TV，该芯片已经发布了苹果iPad平板电脑。
The Apple A4 processor has outdated the Apple A5 processor that was used in iPad 2 released previously which was again replaced by the Apple A5X processor on the iPad came in 3rd generation.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.
Apple A4处理器已经过时了先前发布的iPad 2中使用的Apple A5处理器，该产品再次被第三代iPad上的Apple A5X处理器所取代。 iOS 8发布后，使用该芯片的所有这些设备的软件更新将于2014年停止。
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.
最初的iPad，iPhone4和第四代iPod Touch使用了A4处理器 。 A4的速度在发布时已提高到1GHz，为当时的每个移动设备提供了出色的速度和功率。
