Earlier this week, when Samsung Galaxy S4 Mini was leaked online, benchmarks confirmed that it will be actually using an Exynos 5-series dual-core chip.

Since ARM's big.LITTLE architecture can be scaled from single-core up to 16 core designs, it is possible that Samsung Galaxy S4 Mini with Exynos 5210 might be using such a design where it pairs up two low-performance Cortex A7 cores with two high-performance Cortex A15 ones. Of course, as explained earlier, the smartphone will be able to use either Cortex A7 or Cortex A15 ones, not both at the same time.

Naturally, such design should provide better battery life, at least on paper since we the Exynos-base Galaxy S4 is still to show up in reviews. According to early benchmarks, the Exynos 5210 in Galaxy S4 Mini is clocked at 1.6GHz and scores around 14000 points in Antutu benchmar making it quite slower than the Snapdragon 600 and somewhere in line with the A6 processor in the iPhone 5.

On the other hand, Galaxy S4 Mini will not be in the same league as those smartphones and with its 4.3-inch Super AMOLED screen it should provide decent performance and pretty good battery life, at least if early predicitions around the big.LITTLE architecture are correct.
