Just to recap, the Exynos 5 Octa will fall back on ARM’s big.LITTLE design, sporting a couple of groups of four processor cores, with the larger group consisting of a quartet of speedy Cortex-A15 CPUs, with the LITTLE group carrying also four power-efficient Cortex-A7 cores. A little bit of math shows that we end up with a grand total of eight-cores, leading us to the name ‘Octa’. As one of either group can be active at any one time, the other will go to sleep, in a somewhat similar way as that of NVIDIA’s Tegra 3 chipset. Samsung touts a 3.3x reduction in power usage, and also a cheaper manufacturing price which hopefully, the savings will be reflected in pricing details of devices that use the Exynos 5 Octa chipset.
