Samsung officially announced the Exynos 7 Octa today, the second mobile SoC from the manufacturer to use a 20nm process. The South Korean vendor is touting significant performance enhancements to the tune of 57 percent over the Exynos 5 Octa, which is achieved by using 64-bit CPU cores.
The Exynos 7 Octa features four ARMv8 Cortex A57 cores and four Cortex A53 cores in a big.LITTLE configuration, which means that any assortment of cores can be active based on the use case. The SoC comes with a Mali T760 GPU, which is claimed to offer an increase in performance of 76 percent over the T628MP6 GPU used in the Galaxy Alpha. Other features include support for 2560 x 1600 and 2560 x 1440 displays, ability to shoot high-definition content from both front and back cameras simultaneously and output 4K resolution to TVs.
While Samsung hasn't offered up the CPU clocks for the SoC, from the look of things it looks like the Exynos 7 Octa is a rebadged Exynos 5433, which is featured in the international version of the Galaxy Note 4. Samsung may be looking to differentiate its 64-bit offering, which explains why the manufacturer decided to rebrand the Exynos 5433.
The Exynos 7 Octa is the first product in the new 64-bit series, and we should see more offerings based on ARMv8 architecture next year.
