Very interesting and I look forward to a more detailed analysis of the new cpu in the iP5.<p>I'd be interested in how they handle memory managment/interface and suspect they have done alot of work on that front which would benifit graphics as well as general processing. Might of added a large cache onchip and that in itself will make alot of benchmarks whcih dont have much else running go alot faster than you would expect. This may be the case, we just don't know.<p>Either way you look at it this has to be unique as far as apple phone releases go with lots of people expecting lots and then still falling in love with what is released and with this new one the general press are starting to lose the glaze in there eye's and in parts poo pooing the new iPhone, which is funny as this does actualy appear to be a good product release with perhaps alot of understated features which do more than back up the claim of 2x faster. This in a world were people are expecting any claim of x amount faster to be backed up with small print outlining the conditions that claim is true. but from what it appears as a whole this 2x claim is a very solid claim in many area's of there new phone.<p>I'm not so sure apple have as some are indicating redesigned a whole ARM core, but they certainly could of very easily replaced parts of it and expanded other area's and in that adding cache is one area were mobile phone chips will happily accept and get a good return. Also when you write the OS and have a chip like ARM which you haeve more control to add and change things then optimizing for your operating system by adding a few extra instructions of tweaking the area's your profiling tools have identified as bottle necks and you start to get something realy nice.<p>I'm more a Android chap and never owned a Apple product but this does not stop me appreceiting there finer works of art and for me the iPhone5 has that gut feeling of being a good solid design. OK so it has no NFC but Apple don't do there own credit card, do they, currently - watch this space.<p>I noticied a few comments saying the A6 is dual and this intel is single core, well there be quad cores and they still aint betean it, be looking forward to some more hands on tests with details - especialy the memory interface and amount of cache memory on that chip.

Brand new chip outperforms slow chip from 10 months ago!<p>The Z2460 was launched back in January [1], though phones with it have been very slow to appear.<p>1 - <a href="http://www.theverge.com/2012/1/10/2697790/intel-details-new-medfield-atom-processor-announces-added-android-app" rel="nofollow">http://www.theverge.com/2012/1/10/2697790/intel-details-new-...</a>

This is also JSC vs V8 (and V8's x86 backend is very mature and well optimized; JSC's ARMv7 backend is pretty good, but nobody's ARM backend has had the same time and effort poured into it as their x86 backends).

The title is misleading because the Intel Atom is Medfield, which is a chip (hurriedly) designed for mobile use from a laptop chip by Intel and hence low power. Anyone know how it would do with a real laptop Atom processor?

The article fails to mention that there are at least two contributing factors in the technology stack, raw CPU speed and efficiency of the JS engine.
