iPhone 5s bests all previous iPhones in running iOS 7
A new comparison video that hit the Internet last week shows off the degree to which the iPhone 5s is faster than its predecessors. TheUnlockr took each of the iPhones that is capable of running iOS 7 and put them against each other in a speed test. Apple's newest smartphone, the most powerful to date with a 64-bit processor of course bested all of the previous models. The video, though, demonstrates the progress Apple has made with its handhelds, as the difference in speed between the older devices and the newer models is more than apparent.
The tests begin with a boot-up run, which the iPhone 5s wins handily, followed by the iPhone 5 and then its older siblings in descending order. As seen in the video, the iPhone 5s has been sitting on the lock screen for some time by the time the iPhone 4 - with just an 800MHz A4 processor and 500MB of RAM - catches up. The 5c regularly appears to be just slightly ahead of the iPhone 5, though this may be due to impreciseness in the timing of the tests.
Throughout the rest of the tests - video gaming, web surfing, and so forth - the iPhone 5s outperforms the other iPhones. With its 64-bit A7 processor and a full gigabyte of RAM, Apple's device has consistently outperformed not only its predecessors, but also other high-end phones.
