Samsung Exynos 5Samsung’s 8-core Exynos 5 Octa could eventually be used to power the Galaxy S4. Based on ARM’s big.LITTLE platform, the 8-core chip is consisted of two clusters, four energy-efficient Cortex A7 cores paired with four high-performance Cortex A15 cores that take over when tasks with high requirements are at play. While quad-core Cortex A15 cluster is an excellent performer, it requires too much power for average usages.

The South Korean company has published a video explaining how the processor works, which is available for viewing in YouTube. The video shows how the MP scheduler properly assigns tasks to the right core type depending on requirements. This allows the Exynos 5 Octa to have about 70 percent lower energy utilization than a typical Cortex A15 quad-core processor. Consequently, the big.LITTLE platform won’t be much faster than the standard Cortex A15 quad-core package.
