Samsung announced its latest chip, the Exynos 7 Octa. However, this is not really the all-new offering; rather, the Korean company decided to rebrand its new Exynos 5433 SoC, which happens to power some Galaxy Note 4 variants.
We can understand the thinking behind this move. For one thing, the Exynos 5433 / Exynos 7 Octa is a 64-bit chip and should have an easier to grasp name. In comparison, the Exynos 5430 is a 32-bit SoC, most famous for providing processing power to the fancy Galaxy Alpha smartphone.
The Exynos 7 Octa uses ARM’s big.LITTLE architecture to integrate for powerful Cortex-A57 with four battery-friendly Cortex-A53 cores, all made using Samsung’s 20nm manufacturing process. This, according to the company, should result in a 57% performance boost over the previous generation of Exynos 5 Octa chips. Moreover, the new manufacturing process should also require less power.
Meanwhile, MediaTek has already released its high-end 64-bit chip, while Qualcomm is preparing to start selling the Snapdragon 810 at some point in the first half of 2015.
