Did you know that your Exynos 5433 powered Note 4 is actually 64-bit?

Samsung's Exynos 5433 SoC, found in some versions of the Galaxy Note 4, has been identified as a 64-bit big.LITTLE chipset with Cortex A57 and A53 processors, Mali T760 GPU on Samsung's new 20nm process. A 64-bit SoC, so why is Note 4 only 32-bit?

We already know that Samsung‘s latest round of Exynos 5 Octa series chipsets bring a lot to the table. The Exynos 5433 is perhaps the most popular of the group, seeing that it will ship inside the brand spanking new Samsung Galaxy Note 4, at least for some markets across the globe. Although the Note 4 is a 32-bit machine, did you know that the Exynos 5433 is actually a 64-bit SoC?

That’s right, according to a great bit of detective work from the folks over on Anandtech, the Exynos 5433 is a 64-bit SoC running a big.LITTLE configuration of Cortex A57 and A53 processors. If you recall, the A57/A53 combination is a 64-bit architecture capable of running the ARMv8 instruction set.

We still do not know why Samsung decided to launch the Exynos 5433 version of the Note 4 running only in AArch32 32-bit mode. Good thing Samsung’s new 20nm process capitalizes on some of the other advantages of the A57/A53, which, if nothing else, should see better power consumption than previous A15/A7 and similar configurations. Here is a look at the Exynos 5433, and a few other Samsung Exynos 5 Octa series chips as well.

Beyond the processors, the Exynos 5433 is also rocking the new Mali T760 GPU running at 700MHz.

All in all, the Note 4 with Exynos 5433 SoC is chalking up to be a mighty powerful little unit. So, what’s next for Samsung? That would be the Samsung Exynos 7 series, of which the Exynos 7420 is rumored to be bringing us full 64-bit capabilities through the same Cortex A57/A53 and Mali T760 configuration, but with a brand new chipset build and a few other upgrades. Though we’ll have to wait for Android L and probably 2015 to get here before we see the Exynos 7 series on the streets.

This leaves us with the obvious question, given the choice, would you rather purchase the Samsung Galaxy Note 4 with the Exynos 5433 or the Snapdragon 805?
