According to japanese blog Blue Ringer Men Samsung have developed a quad-core big.LITTLE-based Exynos CPU named 5210. It features one set of two Cortex-A15 and one set of two Cortex-A7 cores working in independence. It is possible that the upcoming Galaxy S4 Mini will utilise the new SoC. Its dual-SIM version will use a dual-core CPU while the HSPA+ version will get the new beast.
The S4 Mini’s existence was discovered last week. The phone will have a 4.3-inch SAMOLED qHD display, Android 4.2.2 and will ship in the summer or early fall.Source: SamMobile
