Update: iOSDoc, which first published these photos has now come out and said they found out they are fake. More from them here.
Every so often, we see sources indicating that they have leaked images of Apple's new devices, and the iPhone 5S (or iPhone 6, or whatever you want to call it at this point) is no different. Obviously, they're not always legit, so a grain of salt is always required.
Recently, some assembly line photos showed an alleged look at the device, but were later reported to be "likely an iPhone 5 clone".
Now, iOSDoc claims to have received some new photos from a "very reliable source," showing an A7 quad-core CPU and GPU, and 2GB of RAM.
The iPhone 5S will come with a new quad-core Apple A7 processor, clocked at 1.2Ghz and iOS 7. The phone’s design will probably be very much similar to the iPhone 5, getting only hardware and software improvements. iOS 7 will also come with a highly improved Siri, able to “do a lot of new cool stuff.” Unfortunately our source didn’t want to speak very much about this aspect.
The new A7 SoC was to be expected, but we didn’t anything until now about the amount of cores or clock rate. It should be much faster than Apple’s dual-core A6, which is clocked at 1.3Ghz. A7 will also feature the PowerVR quad-core SGX554MP4 graphics processor, also featured in the 4th generation iPad. This amount of power will definitely be able to widen the possibilities of gaming, but should get us worried about battery life.
Obviously we can can't confirm the legitimacy of the image, so take it as you will.
