The technical details as well as the processing capability of the new SoC, a member of the Exynos 5 series, are yet to be confirmed. However, Sammobile notes that the Exynos 5210 may feature ARM's big.LITTLE technology which integrates a quad-core structure and is equipped with Dual Cortex-A15 and Dual Cortex-A7 cores.

The speculation is that the Exynos 5210 could also be a dual-core Cortex-A15 chip.

Samsung is reportedly likely to use the Exynos 5210 chip in its upcoming Galaxy S4 Mini. Since the Galaxy S4 runs with ARM's big.LITTLE technology in an Octa-Core processor, its smaller version is expected to feature ARM's big.LITTLE technology in a quad-core structure.
