In the exhibition hall of MWC ARM this year, ARM showed a tablet with Samsung Exynos 5 Octa processor, and demonstrated the advantages of ARM large and small core architecture in the tablet. Under different loads, it will switch between A15 and A7 processors.

Exynos 5 Octa uses ARM's big LITTLE scheme, that is, 4 Cortex-A15 processors+4 Cortex-A7 processors. This is a low-power, high-performance mobile processor architecture. Different processors will be selected under different load conditions. When under high load conditions, A15 architecture chips will be enabled, while under low load conditions, only A7 chips will be enabled.

In the following video, we can see that Exynos 5 Octa uses a Cortex-A7 architecture processor when the tablet is in a low load situation such as browsing web pages, map navigation, and watching videos. When the tablet is in media creation or games, it will use an A15 processor.

In addition, the right side of the screen also shows the power consumption under different conditions. We can see that the power consumption on the right side is 25% when using the A7 architecture, while it will reach 100% when using the A15 under high load.
