Samsung’s Exynos 7 Octa 7870 uses eight ARM Cortex A53 CPUs clocked at 1.60GHz and Category 6 2CA LTE modem with download speeds up to 300Mbps. The modem also features FDD-TDD joint carrier aggregation for better network flexibility – hence the “2CA” in the modem name.
The midrange 7870 SoC features dual image signal processors (ISPs), 16-megapixels for a front camera and 16-megapixels for a rear camera, or 8-megapixels each in dual-camera mode. It also integrates Global Navigation Satellite System (GNSS) with fast time-to-first-fix (TTFF) to enable accurate and rapid location-based services.
“With increased performance and power efficiency, we anticipate widespread adoption of our new Exynos 7 Octa 7870 into mid-tier mobile devices,” said Ben K. Hur, Vice President of System LSI marketing, Samsung Electronics. “Consumers will experience enhanced performance as this is the first time a mobile application processor built on advanced 14nm process is available for these types of smart mobile devices.”
According to some early benchmarks released February 1st, Samsung’s Exynos 7 Octa 7870 will be featured in the second-generation Samsung Galaxy J7 (2016) midrange smartphone with clock speeds up to 1.70GHz, according to the two tests. In GeekBench 3.3.2 running on Android 6.0.1 Marshmallow, single-core performance is 793 while multi-core performance is 4,368. The device is also shown to be running an ARM Mali-T830 GPU.

Samsung claims that its new Exynos 7 Octa 7870 consumes over 30 percent less power than mobile chips built on 28nm High-K Metal Gate (HKMG) process technology at the same performance level.
Qualcomm’s similar chip, the 14-nanometer Snapdragon 625 eight-core SoC, has an X9 modem featuring Category 7 LTE with download speeds up to 300Mbps and upload speeds up to 150Mbps. Both Samsung’s Exynos 7 Octa 7870 and Qualcomm’s Snapdragon 625 have display resolution limitations of up to 1900x1200p at 60fps or 1920x1080p at 30fps, but Qualcomm’s chip can record and playback 4K 3840x2160p while Samsung’s can only do 1920x1080p at 60fps.
Samsung’s Exynos 7 Octa 7870 will begin mass production in the first quarter of 2016, and we expect the first devices to be announced next week at Mobile World Congress 2016 in Barcelona.
