Exynos processors have been used by various Samsung mobile phones and the the Korean giants has presented a brand new model, Exynos 5 Octa at CES 2013. Octa? Octas, as in eight? Yep, that's a processor with eight cores and the rumor is that we can expect to see it powering the Galaxy S4. Samsung claims that this new processor will offer the levels of processioning power that has never before been seen in the mobile industry. Now, I do agree that this is extremely impressive, however, I still have some concerns with all of this.

My first concern is whether or not Samsung will be putting the Exynos 5 Octa into work this year. All the major press say things such as "this processor will enable brilliant user experience, speed and performance". What troubles me is the time tense, if this is something that is certainly finished, why use the future tense? Is this a technology that Samsung has fully mastered and is ready to massively produce or is it a work in progress just like their flexible display technology?
My second concern is how much battery consumption this processor will cause. The Galaxy S3 can proudly say that it has a very reliable battery and you can easily get a few portable batteries to switch between if you are going on a trip and don't have time to charge your phone. I can expect that Samsung would come up with some major improvements to the battery if they actually chose to stick the eight-core processor into their Galaxy S4 flagship.
PC Mag did a nice job of explaining how this processor actually works. Apparently it uses something know as ARM's Big.Little technology, which pairs the small, energy-efficient ARM Cortex-A7 chip with a larger, more powerful Cortex A-15 multicore chip. This technology also addresses the problem of power consumption as benchmarks show that it actually lowers battery drain by half which is really something! This apparently works because "the little guy" handles the easy stuff while the big processor chip is offline to reduce battery consumption. So that means that the A-15 multicore chip activates when we do something that really requires some muscle - such as graphic-intensive gaming or HD video streaming.
