[citation][nom]redeemer[/nom]The 600 series processor is fast enough the Exynos Octo is just a gimmick, correct me if I am wrong its is still essential a quad core so it cannot use all 8 cores at the same time.[/citation]
big.LITTLE can use all eight cores at once, but it's really two quad core CPUs on one die where the second quad core altogether is maybe as powerful as one of the cores in the better quad core CPU. However, IIRC, Samsung will only use the second, weaker and lower power quad core kinda like how Nvidia uses their fifth low power core in Tegra 3. It'll probably be something like that each core of the weaker CPU will be used as a very low power state of the more powerful CPU. Basically, yes, it's essentially a quad core, but it can be slightly more complicated than that.
