Samsung explains how big.LITTLE works on chips like Exynos 5 Octa

big.LITTLE is ARM’s architecture where high-performance Cortex A15 cores (big) are paired with energy efficient Cortex A7 (LITTLE) cores…

The jury is still out there on exactly how efficient this technology really is over regular smartphone usage (and with the SIV likely kicking off with an S4 Pro, the Octa still needs work to do), this is very exciting time for power saving technologies. Thx for the vid!

Even if the SIV doesn't have the Octa, it will definitely not feature a Snapdragon chip. The only reason the SIII in the U.S. had one last year was because Samsung had not yet integrated LTE with the quad-core Exynos chip. It had the quad-core Exynos everywhere else. Rest assured that whether or not it's the Octa, the SIV will have a Exynos chip in it worldwide.

I'd love to take your word for it, but at this point my speculation is as good as yours, and if the Exynos 5450 is not ready (let it be quad or octa variant), there's so much Samsung can do. The Nexus 10 dual core is power hungry and not quite revolutionary in benchmarks, so that leaves Sammy with the S4 Pro if they want record breaking performance.

Samsung has already stated that only Exynos processors will be used in their flagship phones henceforth, so it's not just speculation. The only question is what make. Although, based on what the Samsung engineer had to say about it a few weeks ago, my bet would be on the Octa in the SIV, & then an overclocked version in the Note 3.

Indeed, the benchmarks appeared in january
..I hope they make a die shrink to 20nm for the Note 3, which would take away all the power consumption worries and allow for some serious over clocking..in other words, turning the Note 3 into a true pocket PC.

The exynos 5s will not be ready for phones any time soon. If they use an exynos it will be an exynos 4 and significantly slower than an s4 pro.
@Darac, a phone will never replace my PC, it might if all you do is look at youtube videos and social media. For anyone thats active on their pc playing games, multitasking, editing, modeling and such a phone will never replace the real deal.

So it won't be ready because you say so?
What about those benchmarks?
You think Samsung will blow it like that now that they have the ball?
And use S4 chip for this ginormous yield, instead of their own? Lol dude.
And I was referring to processing power.. with, say, 2.5 Ghz Exynos octa and Mali 658, you have a pc-grade speed.

Qualcomm will probably use something like this in the future, too, and so will others.

I believe Exynos will power the sammy's most powerful and legendary smartphone. S4pro is not flagman processor, Sammy needs its own cpu.

Im geussing their chip will be on the galaxy note III in OCT

Too early for that when gs iv bout too launch this spring / summer

it might but it will be A7 quad core and A15 dual core. not quad core and quad core. i honestly rather have more power Conservative processor because i dont play games.
i would like to see how snapdragon 800 is like.
IF i buy new phone this year i would wait till all the phone are reviewed and benchmarked. i suggest same to u. dont rush.

Cannot wait to see real power efficiency figures, with a GPU and different tasks undertaken and see if this baby becomes a more tablet-oriented chip..... But bloody hell, the mere thought of four A15 cores working together opens up a whole new world of possibilities!

Dear PA, please understand the video properly. This video title has Exynos Octa in title, but it doesn't have anything related to Exynos Octa specifically. It's actually a video done by ARM and posted in it's ARMflix channel back in Oct 2012 --http://www.youtube.com/watch?v
The engineer in the video clearly says that he works for ARM Dietmar Eggemann (firstname.lastname@example.org)
This is just a sample test chip which doesn't even have a GPU. It uses 2x A15 and 3x A7 cores. It's noway related to Exynos Octa. It's just a technical demo, nothing more than that.
Samsung semiconductor channel simply added the ARM video in their own channel, that's all happened. It's in reality a 4 month old video from ARM.

What I really wanna know is if it can play nicely with LTE so we will get this processor in the US.
