Slashgear has a number of iPhone 4 and iPhone 4S to compare their performance in everyday, like opening applications, loading speed and the browser. Obviously the advantage was on the side of a iPhone 4S because the two cores processor and faster memory. And then there was something much more interesting.

Next to iPhone 4S put Samsung Galaxy S II with exactly the same tests. Findings can be interpreted differently.

From the perspective of fans Android, half year old smartphone from Samsung still wins with a tiny margin. For users of Apple technology, this difference is quite noticeable, and they will not miss a chance to tease over owners of "super cool" handsets from Korean manufacturer. And the arguments for this will provide dry statistics.

Galaxy S II has a dual-core frequency of 1200 GHz and a gigabyte of RAM. iPhone 4S dual-core processor operates at a frequency of 800 MHz and has on board a total of 512 megabytes of RAM [9to5mac]
