In iPhone 5S Apple has implemented a graphics chip PowerVR G6430 multi-core which is compatible with the technology Open GL ES 3.0, being one of the few graphic chips that benefit from it. To iPhone 5, Apple Lossless Audio CODEC (ALAC), claims that we should see a doubling of graphics processing capacity, and the benchmarks you can see in this article demonstrate this as clearly as possible. Practically the new graphic face of iPhone 5S benefits from the Rogue architecture designed by PowerVR, and for technical details I direct you to those from Anandtech.
Returning to the realm of numbers, you can notice that although iPhone 5S has very high graphics processing power, the benchmarks demonstrate the fact that users could find much better performance in competing smartphones. Of course, we are talking about different graphics chips and different technologies, but it seems that Apple does not succeed in obtaining supremacy in terms of graphic performance, although in the case of the process we are talking about the best performance on the market. There is a possibility that the software used will give other results after an update and implementation of compatibility for the iPhone 5S, but the chances are small.
In total, iPhone 5S brings that 2x increase in performance compared to iPhone 5, is 2 times faster than iPhone 5C, but in many cases it is not faster than competing smartphones, but everything depends on the benchmark and the type of test.
