I didn’t translate, because I don’t know the terminology very well, and Apple hasn’t yet released the Russian version of the document. An English version is available here: support.apple.com/kb/HT6208

Also, according to unverified information, iPhone4 began to work even a little more quickly. But it seems to me that this is the suspiciousness of the owners. I did not feel any gain.

UPD. My subjective opinion after the first days of using the iPhone 4 with iOS 7.1.1 on board: the virtual keyboard has become noticeably faster to work, and in general the device has become a bit more fun. Increased battery consumption is not noticed.
