Samsung is rumored to put a quad Cortex-A15 CPU inside the Galaxy S IV with the Exynos 5450 chipset, but EETimes is reporting that the Korean company has a more interesting chipset in the works - the first one to use ARM's big.LITTLE technology.
This tech pairs a number of powerful Cortex-A15 cores with the same number of low-power Cortex-A7 cores (similar to NVIDIA's fifth core in Tegra 3). The chipset seamlessly switches between the high and low power cores depending on the load (but it can't run all at the same time).
The chipset in particular will pack four A15s clocked at 1.8GHz and four A7s clocked at 1.2GHz. The A7s will reportedly match a quad-core Cortex-A8 CPU (not that such exist), while the four A15s should offer a big increase over the already powerful A15 duo that powers the Nexus 10. The chip will be built on a 28nm process and pack 2MB of cache.
We're sure that there will be plenty of rumors that this will be the chipset in the Galaxy S IV, but it's more likely to see it in a tablet first.
