Mobile World Congress is approaching, and chip companies have already started making small announcements ahead of the show. Today, Samsung took the wraps off of the eight-core Exynos Octa 7870, a new SoC intended for midrange smartphones.
The chip itself looks solid but unexciting—it has eight 1.6GHz ARM Cortex A53 CPU cores, a 300Mbps Category 6 LTE modem, and an undisclosed GPU that supports up to 1920×1200 screens. More interesting is the fact that the chip will be made with Samsung's 14nm FinFET manufacturing process, which made the Exynos 7420 shine in Samsung's Galaxy flagships last year. Better manufacturing processes reduce the amount of heat produced and the amount of power used by these processors, which gives chipmakers the room to make the chips run faster, consume less power, or do a little of both.
The 14nm process is showing up in more and more places, which suggests that it's growing more mature—it will make an appearance in the new Exynos 8 Octa 8890 that's likely to ship in the Galaxy S7 and its variants. Qualcomm is using the same process for its upcoming Snapdragon 820 and 625 SoCs and the Snapdragon X16 modem.
