Hot on the heels of NVIDIA's Tegra 4 and Qualcomm's Snapdragon 800/600 announcements come Samsung's own next-gen Exynos 5 Octa unveiling. The mobile processor will be the first to implement the ARM big.LITTLE processing technology based on the Cortex-A15 CPU. Dr. Stephen Woo, President of System LSI Business, Device Solutions Division, Samsung Electronics described it as a pumped up combination of existing Exynos 5 Dual and Exynos 4 Quad chips - of which the former is found in Nexus 10 and the later, in Samsung GALAXY S III and Note II.
The key message here is about energy saving despite the enhanced power. Like the Tegra 3 chip, the Exynos 5 Octa activates necessary cores depending on the level of your workloads - there's a total of four powerful Cortex-A15 processors to handle processing-intense tasks along with four additional Cortex-A7 cores for lighter workloads. Samsung promises that the processor will be up to 70 percent higher energy efficiency compared to its previous quad-core chips.
