Apple is upgrading it’s iphone processor from an A6 chip to an A7 chip in the iPhone 5S according to images published by MacRumors,  iPhone 5S will carry a dual LED which will flash different colored hues depending on the surrounding lighting.

“Additional markings on this new iPhone 5S chip indicate that it carries Elpida DRAM, apparently in the same 1 GB amount seen on the A6”. says the report about the device memory, while many latest phones are moving to using 2 GB of RAM this could lead to performance issues.

MacRumors user mozmuder also notes that the image of the new dual-LED flash for the camera seems to have a tungsten filter, which could result in much better looking pictures taken at night with flash.
