Samsung today announced the industry’s first 14nm 3D FinFET mobile application processor – Exynos 7 Octa. Samsung is claiming that the new Exynos 7 Octa chipset provides an improvement of 20% in terms of performance over 20nm based Exynos processors and between 30 to 35% improvement when it comes to power consumption figures.
The Exynos 7 Octa comprises of four Cortex-A57 cores clocked at 2.1GHz and four Cortex-A53 cores clocked at a lower speed for energy efficiency. It also supports LPDDR4 memory interface and comes with the Mali T760 GPU. We still do not have very specific details though on the number of cores that the Mali T760 GPU on the Exynos 7 Octa includes. It should be noted that the Exynos 7 Octa is similar to the Exynos 5433 chip in many ways. Both come with eight processing cores (four Cortex-A57 cores + four Cortex-A53 cores) and include the same Mali T760 GPU. We believe that the Mali T760 GPU on the Exynos 7 Octa may feature a higher number of cores than the variant used on the Exynos 5433. However, without any details revealed from Samsung, we cannot be sure just yet.
As far as performance goes, we already have a pretty good idea of what to expect as the Exynos 7 Octa benchmarks have been nothing short of impressive so far. The difference between the Exynos 5433 and Exynos 7 Octa does seem to be quite significant despite the fact that both share a similar architecture. We should find out more when the Galaxy S6 goes official next month, expected to be the first smartphone to pack the new Exynos 7 Octa chip.
