Apple introduces the A7 chip for the iPhone 5S


Apple just announced the new A7, 64 bit chip set for the new iPhone 5S.  It is noticeably faster than its predecessor, the A6 found in the iPhone 5.  The CPU performance is 40 times faster than the original iPhone!  With the A7 everything you use your iPhone 5S for will be noticeably faster–up to twice as fast!

With the A7 graphics performance the graphics chip is 56 times faster than the original iPhone.  This will give a big boost to graphic-intensive apps and games, and a much faster frame rates as well.  Better efficiency means better battery life for all the things you use your iPhone to do (eg. browsing the web, video playback, cell connection, etc)

The A7 is a modern instruction set, with 2x general purpose registers, 2x floating point registers, over 1 billion transistors and 100 square mm die size.  It contains twice as many transistors but is still roughly the same size as the A6.

    Saying things like “The CPU performance is 40 times faster than the original iPhone!” and “With the A7 graphics performance the graphics chip is 56 times faster than the original iPhone.” Is like saying “The new Intel xxxx chip is 1000 times faster than the original 286!” I mean seriously, so is everything else. LOL It’s called Moore’s law man. It applies to cell phone electronics no differently. Not hating, but that kind of marketing simply insulting if you have half a brain!

      Yea they weren’t very transparent, even with the camera, they mentioned ultra pixels but how many ?

    Also 64 bit. Cool, but when these devices aren’t even pushing 3GB (Newest Android) of RAM yet does it MATTER? No. Especially when this phone is citing 1GB for it’s spec. There’s really no other advantage other than being able to address more memory AFAIK. Camera improvements are cool, but staying low on pixel count though better low light pictures. None of this a surprise, but it looks like until the iPhone6 Apple will remain the fanboi’s choice IMO.

      actually, a 64 bit cpu can also MOVE data around faster than a 32 bit cpu – and if the ALU is 64 bit too (i haven’t checked the specs and am not confident apple would even disclose this) it could also crunch data more efficiently. algorithms that operate on larger-than-64-bit data (say RSA for example) grow less efficient at a non-linear rate (greater than 1) for CPU/ALU architectures less than the data width required (key size, for RSA).

      all of that being said, i’m still not impressed with the new apple devices. i’m biased against them, though, so perhaps impressing me is a bad litmus test for a ‘good product’.

        Actually you’re 100% right (I was thinking in a Windows mindset). If the OS takes advantage it can move 32 bit data two chunks at a time.
