yes indeed but arent the S3's and iP4 the same? or did they created a holy grail of performance with little wattage?

Different architect runs different. ARM chips are small and they do make some heat but not as much They have been making smaller/faster chips for years, AMD/intel had some catching up to do. Now the newest offering of the intel ivy bridge are on par with some of the ARM chips, The main difference between them is ARM is not so good with multi tasking, were the intel/amd are better. Think of ARM as designed for purpose chips were intel/amd is designed for everything chips, What ARM chips do they do it well. If you keep up with the market you will actually see both intel/amd are trying for ARM/x86 coexist in the server market same as x86/GPU with passing specific set of instructions off to the ARM chip.

i dont think that "do specific things better chip" is simply the reason of ARM when it comes to decoding, that is unless they have the decoders programmed to the best use of ARM's instructions.
but in estimations it shouldn't be possible with it, performance/watt would've been breached more than two fold of atom or zacate's if ARM were to manage that.
i'd really like a comparison with them, i mean specially when ARM supports ubuntu, getting an all-in-1 beagle board with a dualcore ARM would be a sweet torrent box and hopefully a HTPC as well dont you agree?

Video codecs on ARM are specific to CPU's.

Curiously what laguage is used for making video codecs? I'm not realy sure if you can still use an interpreted language like Java to make high performance, CPU specific code.

Video decoding is a specific set of instructions think why a gpu handles it better then your average cpu, take your average standalone media player. they used to run a 300mhz cpu with a mips powered hardware decoder only designed for video thats why it could get by using 5watt and decoding 1080p, ARM supports ubuntu now, You can pick up the A10 all winner stuff, it has both ubuntu and android 4.0 images, if you want something cheap and small to play with http://www.aliexpress.com/product-fm/563764893-Freeshipping-Rikomagic-MK802-Mini-PC-Mini-Android4-0-dongle-android-IPTV-google-tv-smart-android-box-wholesalers.html or the http://www.aliexpress.com/product-fm/546571245-Mele-A2000-TV-box-Allwinner-A10-hackable-device-wholesalers.html That will play all your media needs minus the 1080p 10bit stuff, Im still playing with mine to see if I can get a working match for 1080p 10bit, And xbmc has also got hardware decoding working on the Allwinner stuff but not released it yet.
If you want a good benchmark read check out http://www.phoronix.com/scan.php?page=article&item=pandaboard_es&num=1 its comparing the pandaboard. Wich if any of you remember the xbox1 days with bunnie haung he is one of the lead devs on that project

I thought software mode meant it was using the CPU instead of dedicated video circuitry.
