Samsung wants some more clout behind its high power system-on-a-chip, so it's giving it a new name.
While the name for Exynos 7 Octa is new, the chip itself is already on the market in the form of the Exynos 5 Octa 5433, which powers the Korean version of the Galaxy Note 4.
The model of the Note 4 we reviewed is powered by the Qualcomm Snapdragon 805, which is certainly no slouch. In many markets, this is the only version of the Note 4 available.
The Exynos 5...sorry...Exynos 7 Octa sports four Cortex-A57 cores for handling heavy-duty processing and four lower-power Cortex-A53 cores for increased energy efficiency when tackling light loads.
The story behind the story: The Exynos 7 Octa is a beast of a chip, as Samsung says it showcases a 57 percent performance boost over the previous generation. While it has 64-bit ARM cores, the Note 4 it ships with is still running Android 4.4 KitKat, and therefore only supports 32-bit applications. It is unclear if this version of the Note 4 will get the 64-bit version of Android Lollipop or stick to the 32-bit version, to remain consistent with the Snapdragon-based model available in other countries. 64-bit processors are not the end-all be-all of mobile chips, as we explain in this article.
