Considered a “big-little” architecture, the “little” portion, the ARM Cortex-A7 cores supposedly do the yeomen’s work. At some point, this architecture powers down the A7 cores and switches the workload over to the ARM Cortex-A15 cores. It’s unknown at this time if there is any circumstance where both these sets of cores run in parallel with each other. The main processor die has an area of about 122 square millimeters. In comparison to the Exynos Quad, which featured a die area of 78.26 square millimeters, the Exynos 5410 Octa is 36 percent larger in die area than its predecessor.
