Mobile Processor

Exynos 7 Octa (7870)
Unrivaled speed and efficiency
in the mid-range
Exynos 7 Octa (7870) is designed to offer diverse features with enhanced performance and power efficiency for the next-generation mid-range mobile devices. The 64-bit octa-core processor built on an advanced 14nm FinFET process also integrates LTE Category 6 2CA (Carrier Aggregation) modem to support most popular features required for rich mobile experiences.

14nm FinFET Process

More power, less recharging
With 14nm FinFET process technology, Exynos 7870 consumes up to 30% less power than its predecessor built on 28nm HKMG process at the same performance level. With 14nm FinFET process, octa-core 64-bit CPUs offer a perfect balance between performance and power efficiency.

Samsung’s 14nm process uses FinFET structure, unlike the previous process’ planar structure. In a planar structure, gate is attached to the transistor on only one surface, whereas in a FinFET structure, gate is attached on three sides of the channel allowing more effective control of the current leakage than planar. Also, in planar structure, electrons can only move from source to drain through one surface under the gate, whereas in FinFET structure, electrons can move across three surfaces of the fin-shaped 3D structure. Furthermore, with 14nm process’ shorter gate length, which means shorter distance between the source and the drain, electrons need to move shorter distance enabling transistors to switch on and off quickly. Simply put, if the channel is a road, there are more number of lanes that are shorter in length. With more paths that are shorter in length, more electrons can move faster through the channel resulting in enhanced performance.

LTE Modem

Seamless and reliable
connectivity
Exynos 7870 is equipped with LTE modem that supports Category 6 with 2CA offering 300Mbps downlink and 50Mbps uplink speed. And it also supports FDD-TDD joint CA for better network flexibility.

Advanced GPU, MFC and ISP

Richer multimedia experience
On a Full HD or WUXGA display, 3D games and Full HD video playback at 60fps will run seamlessly and vibrantly thanks to Mali-T830 GPU and advanced MFC (multi-format codec). Its image signal processor (ISP) supports high resolution images up to 16Mp for both real and front cameras with 8Mp dual camera mode.
