Samsung's ARM Processor : Exynos 5 Octa Enters Production Line.

Around 20 hours ago, Samsung unleashed its most anticipated Android Smartphone : Galaxy S4 which is shipped with 1.6 GHz Octa-Core Exynos processor. On the same day, Samsung unveiled their new ARM Processor Exynos 5 Octa (28nm architecture), which is not really eight core processor - confirms Samsung Engineers.

Then why named it "Octa" ?

The Hardware Technical Specifications & new technology that are implemented in Exynos 5 Octa is not announced, keeping the critics wondering what's new in this new Exynos !

During CES '13 Samsung shared a very special feature of Exynos 5 Octa processor called "Automatic-Switching".Samsung's Exynos 5 Octa uses 4-cores of Cortex A-15 & 4-cores of Cortex A-7 (thus making them 8-core -> Mathematically, but performance wise it will be less as 4-cores are fast while other 4 cores are slow).

Exynos 5 Octa is capable of switching to core as per need of performance, this can be very useful for power saving of about 70%.

The Exynos 5 Octa's graphics performance has also been improved much than Exynos 4 because it's now powered by "PowerVR SGX 544 MP3" & not "Mali".

We will get into detailed specifications once Samsung officially releases it.

    Anand TamariyaLess than what?

    Less than 8 core processor which doesn't use two ARMs like in Exynos.

    Let me make it simpler :
    In Exynos Cortex A15 & Cortex A7 is used.One is slower than other.

    Now consider an ARM with 2xCortex A15 which means both are running at same speed.

    So,ARM with 8 cores using same architecture in it will run faster than 8 core Exynos which is running with two 4-core Cortex one slow & other fast.

    Hope I succeeded in clearing out the query.

    Hmm.. my point was - why make such comparison when Exynos is the first octa-core mobile CPU in the market! After all, Samsung is NOT hiding the fact that not all the cores run at the same speed. And in mobile market, efficiency is as important as speed (reason why intel is finding it hard to gain traction).

    Exynos is not Octa-core,Samsung itself says so !
    I don't think intel is interested in mobile processor market like Nvidia Tegra series, Qualcomm & Exynos are.
