ARM details Cortex-A12: tomorrow's midrangers to decode 4K video at 120fps

Between the wonders of its big.LITTLE architecture, as found in Samsung's Exynos 5 Octa processor, and the powerful Cortex-A57 monsters done with 16nm, ARM has left room for something budget-minded as well...

"Not bad for phones that will be introduced as midrange in a year, when Cortex-A15 will enter devices"
Cortex-A15 has already entered THIS YEAR'S DEVICE, Daniel :P

Is the exynos 5 Octa having the A15 processors capable of playing 4k videos and recording 1080p videos at 60fps as well? coz these features were not mentioned when the Exynos Octa was introduced..

That's the first question I asked myself on reading this post ! If anything, Exynos Octa should atleast support 4k @ 120 fps !
Anyone there to help, us noobs ? :(

since battery life is already out of question for my exynos GS4, perhaps if these features are equipped in the processor then i'll have something to cheer about..

Whats wrong with your battery life ?! I know its not absoluetly brilliant but it managed to score 65 hrs as against 69 hrs on Snapdragon version.
I am still struggling between Snapdragon and Exynos. So please help !

I have the octa version and my battery life its pretty good, im getting over 4hrs of screen time and 36hrs of use.

it's not the standby time that i'm worried about, but time where the A15 processors kick in during heavy media centric apps like Games etc.., during the time which it drains like hell. It's been a big concern in xda as well go check it out.

Im on the xda forum daily dont worry, right now I have the phone downclocked to 1.4Ghz and battery life its even better plus im still getting over 28k in antutu. Also I got CPU Spy and my phone spends most of the time in 600mhz when in use which is the 4 A7s running at 1.2Ghz, it barely turns on the A15s.

i suggest that If you're in a fix between the two models, you could wait a little more and buy the exynos version right now coz it's not been configured properly just yet.But once it is properly handled it has the potential to be a really good one!!!

Yes the drivers to the Octa are not very good, they wrote on XDA, if Samsung fixes this, it should be better than S600 in power usage. But still, it is very irresponsible from Samsung.

Tegra 4 for instance have support for 4K playback and 1080p/60fps recording. Even Snapdragon S600 can record 1080p/60fps. Samsung Octa can record 1080p/60fps and playback 4K video.
I am not sertain about 4K 120fps. This new Mali-V500 should handle it with enough cores. I have no idea about if these new A15 processors have support for 4K/120 fps playback.
What more conserns me is that A15 is 40-60% faster than A9 and A12 is 40% faster than A9, so A15 will no longer be needed because it is practically unusable in mobile devices because of its high power usage. Sure A15 has longer pipeline than A12. And A12 is 40-bit. But this A12 is too late in the game, 2014 is way too late, this A12 will be similar in performance as Swift or Krait 300 and these are old chips, when new chips will come in 2014 this A12 will be screwed. Actually Qualcomm could take A12 and make an extremely low power core with a good performance and NVIDIA could take this and use it as its fifth core in their Tegra chips.
And this new Mali t-622 should be pretty good, if Mali T-604 takes about 3,8W in usage, this new Mali should take 1,9W. And Mali T-604 is very capable GPU, at 500Mhz and MP4 it produces about 70 GFLOPS which is as good as SGX554MP4 used in Ipad 4 and everybody knows that Ipad 4 has an excellent performance. And if this t-622 will be used in mid-range phones with 720p displays it will be awesome.
So GPU will be excellent, but I am not so sure with the CPU. But maybe I will be proven wrong.

How will intel haswel chips compete about this one?
