    The next-generation A7 processor in the iPhone 5S will be roughly 31 percent faster than the current A6, according to a tweet by Fox News' Clayton Morris. His sources have also mentioned a "separate chip devoted to motion tracking".

    It's unclear how Apple would use motion tracking abilities, but it could be developing a new control scheme that uses motion gestures like Samsung has built into its Galaxy S series of smartphones. A profile of Jony Ive by Bloomberg earlier this year may support this hypothesis:

    Main A-series chip from prototype iPhone 5S
    Separately, 9to5Mac's Mark Gurman writes that Apple has been testing 64-bit prototypes of the A7 chip, potentially for use in the iPhone 5S.
    Last September, semiconductor analyst Linley Gwennap claimed that Apple was working on a 64-bit ARMv8 solution for launch in 2014, and Apple may simply be testing future processor architectures in iPhone 5S prototype units. That report claimed the logical upgrade for the A7 would be a quad-core architecture and continued increases in graphics capabilities.

    Previous leaks have shown an A7 chip -- pictured above -- with an Apple model number of APL0698, while the original A6 had a model number of APL0598. The A6X found in the fourth-generation iPad carries an APL5598 model number, demonstrating how Apple varies the first digit for members of a given A-series family and increments the second digit when transitioning to a new family.

    The iPhone 5S is expected to be unveiled at a media event on September 10.

    Nice road map for the CPU. Every CPU had nice boost to it.

    64-bit seems unlikely since it would require a complete re-write of the iOS kernel, and existing 32-bit applications would need to be run in emulation. Wouldn't we have seen some signs in the developer toolkit if it were 64-bit?

    If so, that means the iPhone 5S will be a screamer!

    I wait until the A10

    Shouldn't the title say 5S to support motion tracking?

    EDIT - Never mind it's been corrected!

    I've always wanted to wave at my telephone to do stuff.

    Good news. I guess all those "ios7 is laggy" remarks should not be an issue anymore when the 5S is released.

    I can see it now... waving my hands around like an orangutan in front of a transparent screen like in Minority Report.

    Yes. Very robust design. The future looks exciting. :apple:

    Lol probably the best visual yet.

    I think that this whole motion tracking gimmick on phones has yet to see much of any use that lasts for more than a day.

    The best use for this would be for iOS in the car, and gaming.

    The most of people jump on 64bit because They can have more than 4GB of RAM. Other reasons are not so important!

    Given that reviews of iOS 7 beta mention animation speed as a critical problem, this would be amazing.

    Also, remember that Apple did not invent the MP3 player, but greatly improved existing designs. Transfer that to motion tracking and it might be a feature "done the right way".

    If this can be used with bluetooth and you can simply put the phone on your desk or living room table to activate stuff on the Apple TV or iTunes, this would be awesome.

    Motion sensors don't have to mean you wave at your phone. You are just recognized by the phone. Maybe infrared tracking or similar.

    I would suspect that Apple would put the new chip in the next iPad first. Then the iPhone the following year.

    64bit doubles the memory bandwidth and therefore the transfer from and to the GPU. That's a major improvement. It's not about address space, but bandwidth.

    So how would being 64-bit help a phone OS?

    Because iOS is based off of Mac OS X, there would be no need for Windows-type 32-bit emulation. Instead an existing 32-bit application would work seamlessly with the OS and kernel, as 32-bit apps work in the 64-bit only Lion+.

    More power is always welcome .. The 5 is no slouch
    .heck my 4s was no slouch ... Im not sure about the motion tracking thing though .. Look how well Samsung did it :/ ..let's wait it out

    64-bit unlikely in A7. It's like toy bricks. Apple will add only one brick in one generation to keep you buying their products all the time. If they boost the configuration too much in one generation, there would be less excitement in the next one. Diminishing returns.

    Even if the new iPhone has only 1GB of ram, there would be massive improvements to iOS' already great memory handling. In a 32-bit UNIX OS, every process needs to share the same 4GB virtual memory address space that is owned by the kernel. In a 64-bit OS, each 64-bit process gets its own 16TB virtual memory address space. While 32-bit processes still have to share the kernel's 4GB virtual address. This leads to much faster processing as 64-bit processes don't need to go through the kernel to process as much information.

    How about lower power consumption for better battery life?

    Only 31% faster? I don't know how they determine "2x faster" but this doesn't seem like much of an improvement.

    So A8 will be a Quad ? So makes sense to wait for next year ?

    They should've just done 64bit on iOS from day 1. Obviously this day would come eventually. Intel and AMD had 64 bit processors in 2003-4.
